"That liner's FUCKED though"
idk why but that made me laugh out loud
Lol yeah while I was editing this I noticed I said that. Sometimes I think out loud and don't mean to haha.
One thing, the liners were used by MPs up until the mid 80's when the MARTE 1 was adopted. By the 90's the Spanish army had already widely adopted the MARTE. My father and a work colleague dud their military service during those times.
This was a fun video to watch...agree that's a pretty well made helmet considering the punishment you put it through. Your video left me imagining what a .454 Casull round would do to it 😁
Love these vids
given the steel's behavior (much tougher than mild, yet more ductile than martensite, and sometimes some unexpected brittleness) i think it is hadfield (aka austenite with 12~13% manganese) wich is a type of steel very commonly used in western helmets (may it be british brody, american M1, french M51, etc...) as it is significantly better than simple mild steel, while ductile enough to be cold-drawn (and the manganese cause some work-hardening, wich can be why some weird brittleness happen in some areas, as the work-hardening induced by the cold-forming of the sheet of steel)
Hey I see a M715 there you should do a video on that.
What if I already did?
It looks more like high strength carbon steel then stainless
Could be. I know it was very thin and performed quite well. I'm no metallurgist.
How can you tell?
@@MikeB128 I did look up on some of the thickness on the steel helmets from World War I and II and apparently a lot of them are very thin, they're actually thinner than most medieval helmets from what I understand.
I think the Swiss steel helmets are about 1.2 mm thick, while the American M1 helmet is only 1.15 mm thick! The French World War I and II steel helmets were made out of 1 mm thick mild steel if I am not mistaken! 😬 I would rather have a medieval/Renaissance helmet then the modern steel Frech one if that's the case.
To do a comparison to Medieval/Renaissance and modern steel helmets:
From what I understand medieval helmets are usually about 1.5 mm and 2 mm thick, some are 1.2 to 1.3mm thick and quite a few are 2.5 mm thick. However most medieval armors were made from mild steel (mail & plate) and it was somewhat common for these mild steel armors to be case-hardened too. Does also cold forging techniques done for mild steels sheets that were thinner instead of a giant block that needed to be heated up and pound it up into a sheet. Either way it will be very strong.
I have a cold forged mild steel Crusader helmet of 1.5 mm thick and that thing feels very, very solid, it just feels more solid than the original M1 steel Helmet, or even the modern steel Swiss helmets I have which I personally find strange.
There's also quite a bit of European armors made out of higher carbon heat-treated steel that can flex very well! Those were probably heat forged.
Crazy enough the Chinese armour during the same time period however from the evidence I could gather it seems that their metal armors are made out of just raw iron! Yikes!😬
Now saying that it seems that the Japanese experimented with case hardening with some surviving examples. As for the Chinese armor made out of iron, I have no idea why only the surviving examples I could find info of are only made a raw iron.
As for the modern steel helmets, most of them seem to be thinner but had way more advanced alloys and different alloys; the American British use the I believe it was 8% manganese Steel, why the Germans use some kind of chromium steel nickel alloy. As for the other alloys on other helmets, I'm not sure. It seems like many nations were experimenting with different alloys until Kevlar and other strong composites came along. (I also have a few Kevlar helmets from different countries)
What is the best steel helmet in your opinion?
For what application?
@@MikeB128 general military use for a soldier
Pretty cool to see that liner being just enough to stop the round. I picked up one of these from you a fair time ago (one of my favorite examples with graffiti/trench art might I add), and it's nice to know these seem fairly stout!
