The difference between 304 and 316 stainless steels

[@keystonekreative2174]

Thank you for explaining this!!!

[@edhuber3557]

AA: Thanks for an alternative-view from the practical & salvage side. On design/fab side we use some of same field ID methods....and in past 1/2year I've twice has very seasoned Craft mis-report-by-site on highly weathered (& hard to access old in-cell plate) ....once SST-misID-as-Al, and once the reverse. Only when we started job to cut on it that we saw the error. Some thoughts: "mole-ib-den-um" or sometimes slang as 'moly'.

Thank you

Work hardening will make at least 304 magnetic. Even without work hardening, a tiny neodymium magnet will often stick to 304 without falling off. Take a pressed or bent 304 product, put a magnet where it's bent, it will stick. Heat it cherry red, let it cool, it will again be almost completely non magnetic.

Perfect comment, now I know what prop-shaft material I should buy, SS316 was a nightmare, once I put bearings on that shaft the only way to remove or replace them was to cut them with angle grinder. SS304 seems like a better choice, so thanks man.

[@zefrum3]

@@Eden_M dude 316 is way better than 304 for machine parts, especially those going in the drink. Cant say i know why u had that experience but 316, actual 316, is the way to go.

[@Eden_M]

@@zefrum3 Sliding bearings on the 316 shaft would easily scratch the surface compared to the 304, and not even press fit, you could insert them by hand and they would get stuck (on the 316). So you might be right, probably wasn't true 316.

Thank you so much sir very informative video. Could u please tell me the name of the metal which u showed at the end of the video

[@ArtisanArmoury]

Hafnium is a chemical element with the symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals. And it is outrageously expensive!

@@ArtisanArmoury thank you so much sir

[@AyushJrKrusade216Holders]

Molybe-de-nium, Nice

[@ArtisanArmoury]

My whole metal recycling career I always called it Moly so it's a little foreign for me to refer to it by its whole name... as you can tell.

[@AyushJrKrusade216Holders]

@@ArtisanArmoury great content btw, was really knowledgeable and yes I will call it Moly from now on. Thanks !

[@zefrum3]

LOL!

[@tictoc7794]

Stelitte is it ss304?

[@daneyums1195]

Can I place mouthwash in hip flask with 304 steel?

[@basketofdeplorables4253]

Nothing like keeping your mouth clean while appearing to be an alcoholic.

[@ArtisanArmoury]

Sorry I did not see this till now. Yes 304 would/can hold up.

@@ArtisanArmoury thanks! Appreciate it❤️

[@sergiiiaroshenko5012]

304 stainless good for honey i need extractor ? Or after 2years rusted?

[@ArtisanArmoury]

It should not rust unless exposed to fire or salt and even in most of those cases the rust is only topical. When my 304 rusted it was after I used it in the smelter at over 2000 degrees F. So you should be good to go.

[@unkono]

@@ArtisanArmoury I have a solo stove.a gassifing wood stove made of 304 stainless steel. It started to rust after first use. And I did wipe it with a damp paper towel. Cleaned the rust right up with vinegar. It gets over 2000 degrees

[@savedfaves]

304 rusts in my garden exposed to rain. We are seven miles from the sea.

Molybdenum: muh - LIB - dih - num

[@ArtisanArmoury]

Thanks but I figured it out.

[@paducahandlouisvillerailro1694]

I have a rare 316 stainless steel Illinois Central railroad spike

[@ArtisanArmoury]

Cool. Is it marked 316?

[@joslinnick]

Muh-lib-den-um

[@ArtisanArmoury]

I think I'll just stick with Moly

[@hgfcxz721]

Which one is the marine grade?

[@ArtisanArmoury]

316 would be closer to marine grade but they usually use alloys for the ocean such as Alloy 20. Titanium is the metal of choice for use in the ocean, as it is for all intents and purposes it is corrosion-free.

[@zefrum3]

Marine grade steel is indeed generally considered 316. A lot of aluminum alloys are also marine grade even without passivization (anodization). Titanium is not going to be used in marine applications except for extremely expensive condensers, submarines, drill rigs, etc. Alloy 20 isnt used much for marine, its main purpose is for petrochemical production and synthetic fiber production.

Pronounced MO-lib-den-um...

“…Zinc coated iron…” really? Dont listen to this guy; he is very far away from a metallurgist or simply informed

[@ArtisanArmoury]

Are you a metallurgist? Or are you just one of those people that think you know everything? Do you know how to use google? B/c zinc coating is very common. Here is a quote from 1 of the 100s of websites "The duller galvanised finish or shinier zinc plated finish... Both methods add a protective layer of zinc to the steel." Or is it b/c I said iron instead of mild steel? I so look forward to the day people answer for their unfiltered mouth! (Matt 12:36)

[@zefrum3]

@@ArtisanArmoury i am an engineer. You said, again, “zinc coated iron” which is incorrect an should be embarrassing for you given you are making instructional videos. Jesus said ‘turn the other cheek;’ Never go full retard.

[@ArtisanArmoury]

​@@zefrum3I would be embarrassed if I when around acting like you. I was thinking with scrap metal on my mind and that bolt would be referred to as ''short iron''.. You miss the more important topic though when you act the way that you do and you WILL answer for your pride if you don't repent.(Isaiah 2 12) I suggest you turn your life over to Jesus.
