Great information but due to the shear amount it would be immensely effective to have some form of narration being done. Any kind of sound, the info is great and becomes daunting without catering to other senses other than sight.
i stopped at 2 minutes...the video ends 8 minutes..thought i was going to learn something here, but wait..all is not lost those 2d pics are something to ponder over..best part
Best one for making a knife would be martensitic stainless steel, because of its hardened martensitic crystal structure. Its very hard, not ductile, so tour knife will stay sharp for longer.
You are asking for competing qualities lol. If it holds an edge longer, that makes it harder to sharpen. If you want it to hold an edge longer, it won't be able to be sharpened as sharp. If you want it to be corrosion resistant, you will have to reduce the ability to get any of the above qualities. For somewhat of an actual answer, Leatherman uses 420, 440, and sometimes 154cm in their blades, and I have never had any complaints.
I’m curious.. where does 7Cr17mov fall on this? I know its Chinese based but I wonder what it’s comparative to and if it’s good Steel for kitchen knives and pocket knives
D2 is not technically a stainless, though it may (if my memory serves me), have small amounts of chromium. Recall that a stainless steel constitutes at least 10.5% chromium by weight. D2 is a tool steel.
I have machined all these steels. duplex f51 is difficult to chip. all soft compared to the inconel range... now we're talking. 718.....625... mega steels.
We need Spring Wire Size: Φ 1.00±0.01 mm Properties of Material : a) Mechanical: Ultimate Tensile Strength (UTS): 180~200 Kg/mm2 Twisting No.: 20~30 Time b) Chemical: Carbon= 0.08%~0.10%, Silicon: 0.44%~0.50%, Manganese: 1.20%~1.25%, Chromium: 15% (Min), Nickel: 9% (Min), Phosphorous: 0.025% (Max), Sulfur: 0.003% (Max)
Such a great animation! Expensive. Narration really required for a topic like this. From a Training development POV, what are the end products made? What is a Henkle knife vs a turbo jet fan blade? Explain like the audience is a third grader. Basic language, simple analogies and the like. If it was my gig, I would make five shorter videos.
Which is most durable and superior in strength and non degradable in other words look the same thousands of years from now and not affected from any elements? Let’s add some diamonds!
I suppose you are not intending to cover all grades but not including 310 / H7 is a bit of a mystery. It is the highest alloyed grade with around 25% Cr and 20% Ni.
200 grades are less strong and corrosion resistant than 300 grades. What are you trying to do with it? That's the important thing. There's a perfect steel that matches what you're trying to do. It's not always as cut and dry as "What's the best quality?" Depends on what you're trying to do with it!
Please add narration, I did not watch because it is so much easier to learn this stuff when you can listen to someone, hear how they say it, and there are many other videos, which I will now go find, sorry.
I started hoping for sound but quickly realised it was not necessary! wicked!
good work on clear laying out of the different SS grades with loadful of important informations even students can understand...very helpful.
One of the best videos on RUclips.
Maybe one of the best stuff on the internet.
Thanks for posting this video. Im filling out permits and was trying to figure out the difference between the 316Ti and Type 430!
wooo! What a difference between those two! my lord. If only 316Ti could cost the same as 430, the world would be a vastly different place.
Would love to have a wall poster of this. Fantastic for my workshop and conversation starter.
Great information but due to the shear amount it would be immensely effective to have some form of narration being done. Any kind of sound, the info is great and becomes daunting without catering to other senses other than sight.
I just played some techno music in the back haha
i stopped at 2 minutes...the video ends 8 minutes..thought i was going to learn something here, but wait..all is not lost those 2d pics are something to ponder over..best part
I know, right! let's get some music up in here!
I would love to be able to hear this, reading it on my phone is almost impossible and my eyes aren't that good anymore
Great information. Thank you for sharing 👌👏👏🙂.
Brilliant, just what i needed. Thanks
Great video!
Nice video, I only know (and work with) 304, it's good to know there are some other types of stainless
We have been become well-informed.
This is the very clear idia to metallurgical students,
Thanking You,

Very nice overview!
this is a good video,now i know more about ss 👍,thanks for your teaching
amazing video. thank you.
Fantastic overview of the confusing (to the newbie) array of stainless steels that are available.
thanks! great vid
Amazing job, thanx
Really, very helpful video. I wish if I could get this in PDF format for the ease of searching
Superb
How we can identify it can u plz give one video on spark testing of stainless steel
What's the best stainless for electrolysis? And how can I tell on random screws, bolts laying around my home?
very nice video explanation on stainless steel
So great!
Very informative... Thanks for sharing these...
Better Explained, very good.
Is the 420 steel a good metal for a knife?
Highly informative .
Which grade steel is used in loudspeaker magnet structures? Can we use galvanised low carbon mild steel or ferritic stainless steel?
so whats the best one to make knives out of? the one that will keep a sharp edge longest and easy to sharpen
It's the one that knives are made out of.
You are asking for competing qualities lol.
If it holds an edge longer, that makes it harder to sharpen.
If you want it to hold an edge longer, it won't be able to be sharpened as sharp.

A downloadable PDF of the whole chart would be nice.
I’m curious.. where does 7Cr17mov fall on this? I know its Chinese based but I wonder what it’s comparative to and if it’s good Steel for kitchen knives and pocket knives
How to know to if an alloy is "food grade" and/or fire resistant? Thanks
Excelent video
this is very good video.
u are the captain sir
Excellent video
Thank you 🙏
extremely informative
430-grade stainless steel: for brackets in a BBQ will it be ok
Which grade will be used for Tesla's Cybertruck?
Make video on titanium grades pls
I guess the best stainless-steel would be the duplex but probably very expenive
Good graphics, would be useful in printed form for trainee engineers.
Where does Inconel place at?
wonderful
What the specifications for 1.4116 stainless steel?
What's this sound track called?
OMG! I thought there were two types, 304 and 316. Talk about Dunning-Kruger....
THANK U SIR
I love steel
Thank you Sir
thanks
Where does D2 come in here? I have a K-Bar of D2 and am looking how to best sharpen it and maintain it, etc.
D2 is not technically a stainless, though it may (if my memory serves me), have small amounts of chromium. Recall that a stainless steel constitutes at least 10.5% chromium by weight. D2 is a tool steel.
D2 is not stainless.
got it !!!
I have machined all these steels. duplex f51 is difficult to chip. all soft compared to the inconel range... now we're talking. 718.....625... mega steels.
We need Spring Wire
Size: Φ 1.00±0.01 mm
Properties of Material :
a) Mechanical: Ultimate Tensile Strength (UTS): 180~200 Kg/mm2
Twisting No.: 20~30 Time
b) Chemical: Carbon= 0.08%~0.10%, Silicon: 0.44%~0.50%,
Manganese: 1.20%~1.25%, Chromium: 15% (Min), Nickel: 9% (Min),
Phosphorous: 0.025% (Max), Sulfur: 0.003% (Max)
So Molybdenum also slightly increases corrosion resistance?
Very much increases. It's sea resistant so boats should be made of this stuff.
useful information

I'm interested in 15-5 PH SS. Relevant time points:

So, I think I want all appliances, my kitchen sink, my grill, my grill utensils, and my cutlery made out of 904L?
Good
Should have shown this(7:55) at the beginning of video.
301...... the *BEST*
There will be a quiz at the end of the presentation
This is just class and brilliant!!!
great, relative ideas for scholar to decrease the effective work to decrease the carbon content.
Which is most durable and superior in strength and non degradable in other words look the same thousands of years from now and not affected from any elements? Let’s add some diamonds!
Being there is no sound, a poster is all the video is good for.
A slight nightmare of choice. I just want max anti-corrosion crossed with tank strength. Simples.
what about 13-8?
commonly used SS304
304L is for Starship!
still no audio !!!
I suppose you are not intending to cover all grades but not including 310 / H7 is a bit of a mystery. It is the highest alloyed grade with around 25% Cr and 20% Ni.
A240?
Rich with info but a video is not the best media for such details
Add music will be better
Sir I watch video steel grades but plz explain me ' iron grades' minz low aron..-En. - En 8 - En 31....wsp...explain perfect chart low to high...
what about 204?
200 grades are less strong and corrosion resistant than 300 grades. What are you trying to do with it? That's the important thing. There's a perfect steel that matches what you're trying to do. It's not always as cut and dry as "What's the best quality?" Depends on what you're trying to do with it!
Where is Inconel?
Ken Knerr inconel isn’t stainless steel
Where is 202
hi
Good information. Shit production quality.
No sound??
Please add narration, I did not watch because it is so much easier to learn this stuff when you can listen to someone, hear how they say it, and there are many other videos, which I will now go find, sorry.
Why no narrator? Seriously WTF?
No audio knuckleheads... I can't chew bubblegum and learn at the same time.
No voice…. Not good
Lack of audio sucks!
Yes, yes… autistic stainless steel. My favourite kind
so whats the best one to make knives out of? the one that will keep a sharp edge longest and easy to sharpen
316L is harder than 904L
@@toocoolforu I thought 904 was harder?
