Basically the economy S/S , grade 430 , has NO nickel and it's magnetic . The higher grades , grade 304 and 316 are non magnetic . The 304 is used in better grades of commercial kitchen equipment . The 430 is in the economy equipment . Some equipment is mixed with a 304 top and 430 under shelf and legs . Or a sink with 304 bowls and the rest 430 . A 316 grade would have more nickel and be used in a commercial kettle lining to resist food acids . There are several other grades . Again , if magnetic , it's economy and you will only get a lower price as " steel " as scrap . The magnet doesn't lie . But people " think " it doesn't rust . But if abused , it definitely WILL . Salts , acids and chlorides will corrode it .
Good general basic but the magnetism part was not accurate. Magnetism has nothing to do with the quality and cost of stainless steel. There is another family of Stainless steel which has better performance against corrosion and strength. Its the duplex family. It's also magnetic. The popular grade will be the 2205. 22%Chromium 5%Nickel 3% Molybdenum. Same material used in building the Singapore Marina Sand's Helix bridge due to its superior corrosion resistance and strength (able to use smaller members to increase the aesthetic).
After reading the comments I will say this - this is a good overview of the process. It will give anyone a good base to search out more in depth discussions on the process of creating SS and the different grades/types.
As a one time fabricator, i HATE stainless steel with a fiery passion. Great for the finished product. But my god is it a royal pain in the ass to work with.
Sorry for asking the obvious or triggering everyone, but is it really THAT hard to work stainless steel on? Like, "the harder it is the harder one has to work it with" kind of thing?
In 1936 Ford Motor Company built six 1936 Ford automobile complete bodies in stainless steel, then in 1960 they built two 1960 Ford Thunderbird's with stainless steel bodies and lastly they built a 1966 Lincoln Continental four door convertible in stainless steel. GM got into the act in 1957 by adding stainless steel roofs on their Cadillac Eldorado four door cars.
Started watching this one and wondered what the hell i was thinking. Have a mixed history with stainless steel plate as I worked at the Port Kembla steelworks here in Australia in the mid ‘80s to mid ‘90s processing both magnetic and non magnetic stainless steel which tends to see you developing a hatred for it specially moving the stuff as was my job both as a crane driver and as a chaser. Anyway great video thanks for the share.
The chrome makes it hard to drill holes etc There’s magnetic and non magnetic .kitchen bench tops are non magnetic And fridges are magnetic , as scrap steel the the more chrome added the more it’s worth Also stainless has grain direction (like wood ) so it has to be be folded a certain way . It’s possible to weld stainless and mild steel together ,that is a little involved
@@stevenmonson5149yep not involved at all really. I'm a weekend warrior basement TIG guy and got mild to stainless easy. 309 is great stuff when you aren't exactly sure of the alloy you're working on.
One of the forms I get to see stainless steel is in molds that might weigh 8k pounds, some more and some less, for injection molding plastic products. Thanks for the video.
I endeavored to make small passive solar tanks - for hw, using two ss deep dish rectangular pans (bought retail) welded together. I was in Thailand at the time. A regular welder couldn't do it, so I found a specialist. He welded it, but it was costly. I had planned to make them to sell, but the welding cost compelled me to abandon the project. A search online reveals nothing as simple as a black ss tank for passive solar pre-heat of water. I'm 72, but if I was younger, I might re-devote my energies toward reviving that project.
"Stainless" is a misnomer as owners of DeLorean cars soon discovered. Stainless steel may be corrosion resistant but it is not "finger-print proof." The original "18Cr-8Ni" stainless steel composition was discovered accidently in Sheffield, UK, by a man named Brierly. He'd been doing some work with steel samples of different compositions that he'd left exposed to the UK's miserable climate. Some months later he found that all except one displayed surface corrosion. Quick analysis of the uncorroded sample and------- the first stainless steel.
I think Krupp in Germany may have had a big impact on stainless development, they were developing armor plate, and found nickel alloys had the toughness necessary for this service. This was around the turn of the last century.
@@whaleh8er991 There are sword blades in the Tokyo National Museum from the 12th century without a speck of rust on them. Evidently there are iron ores that contain chromium and nickel, naturally.
In South Africa, we use ss its the easiest thing to weld but it warps and pulls, way more than carbon steels. To get a great finish you pickle and then passivate it and it comes out beautifully. TIG and SMAW are most common with Fluxcore for longer welds. Xray results are impressive. We've developed a high carbon stainless called 3Cr12. Now, there's an amazing steel. it's like carbon steel that doesn't rust
What I kind of missed is any talk about the amount of carbon in the alloy, in so far as I know, carbon is an important element in this mixture with the alloy to become steel.
No actually steel does not have to contain carbon. In fact in many steel grades like stainless 304L, 316L and the interstitial steels carbon is kept down in the parts per million range.

Not to be nitpicky but your video made it sound like Pig Iron was pure Iron, but it's actually an alloy of iron and carbon. By definition steel can't be steel without carbon so I was a bit confused the first time I watched the video.
Great documentary. It is said that components are added to increase the steel's strength and hardness. Then how come that INOX screws are so much softer than normal screws? They are likely to snap when you don't drill a hole in advance. Just wondering.
It’s not just material components, it how the material is treated as well, such as heat treating and tempering or even chemical treatment , this is why in the US you can not use screws for timber framing construction, screws snap and shear, but nails bend without breaking, this I’d do to how nails are made by drawing metal wire through progressively smaller dies, there is no cost effective way to manufacture screws in this manner to impart the same properties that die screws does
Stainless steel is a miricale steel, but used with a disimler metals acts of electrolisis take place.Such as stainless steel moldings on outside trim and fastened to steel? I t will rust right on through the steel. Even faster on a salt invirement?
I was a metal fabricator in the pharmaceutical industry for 36 years working with stainless steel exclusively. It's not too much of a challenge after you come to understand it's properties.

It's not a challenge if you do it right, welding is awesome especially Tig, as for drilling make sure you have the right bits and slow it down and make sure you use cutting oil or coolant, and cutting it's not much different than other steel just go a bit slower and watch the cutting edge.
I never clean my frying pan with soap, and only rinse it with a light use of a sponge, once every 2 or 3 uses. That way, it forever has a clean black 'seasoned' coating. In my dish drying tray, there are 2 hard plastic bowls and 2 metal spoons. That's all.. Simple is better.
Here's one for you: how is it certain ancient civilizations such as the Egyptians achieved construction wonders that have last through the ages to the point some give the credit to aliens, but only on rock but never got to discover steel? Or the Japanese, who were known for their craftsmanship with metals couldn't come up with something as "simple" as stainless steel for building?
Thanks for the information. Can stainless steel be cut with an acetylene torch? I found a weird plate of metal in the road once. It won't get red hot even from an acetylene torch and thus can't be cut that way. It's only 1/8 inch thick. I felt like I found a piece of an alien space craft.
When Boeing was building the Minuteman intercontinental ballistic missiles I’m pretty sure that’s the project. They were having problems with the storage tanks for the fuel having corrosion problems and there was this little steel male not so little but not as big as some in a little place called Butler Pennsylvania. It was arco steel they figured out the mix they needed to make tanks that wouldn’t corrode.
So, comment at 3:48 the ingredients are “thoroughly mixed “ I’d really like to see how all these ingredients are evenly mixed. It sounds almost an impossible task to achieve a consistent product ??
I don’t get why certain people believe everything should be dumbed down. Surely adding a few details they might not understand wouldn’t ruin the whole thing for them, while for others it’s those details that add 80% of the value over what they already know. Have people forgotten the art of smiling and nodding?
@@solvated_photonIt's the American way! Probably because of the advertisement requirement brainwashing and the 'don't want to scare off the customer culture' from their advertisers? Stupid I know.
How do they know when the correct amounts of added ingredients are achieved. That is, when adding nickel, even though they may drop in X pounds into a vat of liquid steel (Y pounds), how do they verify the exact correct ratio? Remember, the steel is 1900 degrees C. How is an analysis done at that hot temperature?
Same way as with any other steel: they take a sample (yes, this is possible. They use a small ladle with a very long handle.), poor it into a small mold, send it to the on-site lab, do a quick scan, and report back to the shop floor.
I once had to make 2400 ft.of 24 ga. Stainless gutter in the family run business many years ago. It was for a giant warehouse on the Port of Houston . Very brutal on the shear, and hard to bend in the brake. Gorgeous looking gutter though.
@@robertjackson2663 When drilling it use bees wax. Drill a little to warm the bit and the hold the beeswax block to the bit to melt a little wax on the bit and repeat often. Works great!
Yeah but you're not mentioning the temperatures. Like chromium, that has a higher melting point; molybdenum even higher (2623°C). So, how do they not burn the lower melting point elements and there has to fluxes used, or catalysts? This is the how do they do it?
@@bobdevries4028 a scrap metal dealer told me that since there are so many grades, with different alloys, which lowers the value. What he wants are large quantities of the same grade, for example mill scrap.
Their is a grade of stainless commercially coded 600. It is fairly inexpensive and used in applications where it is painted, street furniture being a good example. Unlike normal steel. it still has a fairly high resistance to corrosion when the paint is chipped. It can also be used in street lighting applications. Not having the corrosion problems of normal steel, where rusting increases it's volume by 13, it can be used in reinforcement for concrete fence posts, window sills and prefabricated concrete garages. Normal steel in these application needs a minimum concrete cover of 2 inches. These 600 grades an be made from scrap. They were considered for car manufacture, but they were too brittle to pass the crash tests. When induction hobs were introduced, a normal steel plate had to be buried in the base of the pan. Unfortunately it's size and positioning can vary efficiently wildly. The early pans cost a fortune. During testing, Bosch tested a grade 600 enamelled Asda (Walmart in the US) pan that cost a fraction of the price. Having magnetic properties throughout it outperformed all the others and did not have the problem of hot spots. Unfortunately, the properties included the handles, which were reaching more than 300 degrees. So that was that. LOL

Same way as with any other steel: they take a sample (yes, this is possible. They use a small ladle with a very long handle.), poor it into a small mold, send it to the on-site lab, do a quick scan, and report back to the shop floor.
@@wtflmaa7842 When you say "do a quick scan" what is the machine that does it?
@@terry_willis State of the art is mass spectrometry.
Where is Carbon in this steel? I thought Carbon was a part of Steel- alloy.
Why is it sometimes not magnetic?
austenite
It’s rustless steel ,not stainless steel . It will stain .
Just turn 180 and sum over there then.
SS is nice, EXCEPT for galling. Not fun.
Cleetus when it didn't want to start it was in nitrous lock and the you made even worse with ether locked it up even worse.
Much harder to work with. You use it only when you really need it.
I once had to make 2400 ft.of 24 ga. Stainless gutter in the family run business many years ago. It was for a giant warehouse on the Port of Houston . Very brutal on the shear, and hard to bend in the brake. Gorgeous looking gutter though.
Drilling it is slow and hard to do, go fast and the bit goes to shit right away, but thr end result is great.
@@robertjackson2663 When drilling it use bees wax. Drill a little to warm the bit and the hold the beeswax block to the bit to melt a little wax on the bit and repeat often. Works great!
Yeah but you're not mentioning the temperatures. Like chromium, that has a higher melting point; molybdenum even higher (2623°C). So, how do they not burn the lower melting point elements and there has to fluxes used, or catalysts? This is the how do they do it?
Carbon is not an impurity!
How stainless is steel made? (sorry, I couldn´t resit to ask)
Something above 97% of stainless steel production is remelt of scrap….usually in an arc furnace.
One drawback to stainless steel is recycling; since the exact alloy composition varies, scrap stainless is not desireable...
I still get good money when I take it to the scrapyard.
@@bobdevries4028 a scrap metal dealer told me that since there are so many grades, with different alloys, which lowers the value. What he wants are large quantities of the same grade, for example mill scrap.
Their is a grade of stainless commercially coded 600. It is fairly inexpensive and used in applications where it is painted, street furniture being a good example. Unlike normal steel. it still has a fairly high resistance to corrosion when the paint is chipped. It can also be used in street lighting applications.
Not having the corrosion problems of normal steel, where rusting increases it's volume by 13, it can be used in reinforcement for concrete fence posts, window sills and prefabricated concrete garages. Normal steel in these application needs a minimum concrete cover of 2 inches.
These 600 grades an be made from scrap. They were considered for car manufacture, but they were too brittle to pass the crash tests.
When induction hobs were introduced, a normal steel plate had to be buried in the base of the pan. Unfortunately it's size and positioning can vary efficiently wildly. The early pans cost a fortune. During testing, Bosch tested a grade 600 enamelled Asda (Walmart in the US) pan that cost a fraction of the price. Having magnetic properties throughout it outperformed all the others and did not have the problem of hot spots. Unfortunately, the properties included the handles, which were reaching more than 300 degrees. So that was that. LOL
I thought this was (how it's made) nope. It's not.😮
I already knew..thanks dwarf fortress 😂
I wonder if they could make me some stainless underpants.
Why can't you use "degrees F?"
How come when carbon steel touches stainless steel, it contiminates it and causes rust and decay immediately?
Can only bend it in one direction once and hard to work with. But, does last like nothing else. 😊
