[Bryn-gwlad] spring stainless (410)...interesting factoid!

[Jason Bressie]

The past two months I have been working with 410 in making my scales for my shirt. I bought five sheets of .032 410 stainless and had them cut them into bands for scale making. After grinding and shaping 827 scales as well as doing some heat treating experiments in Sir Gaston's kiln, I have come to some facts about it. 410 is more difficult to work with than mild, but easier to work with than 304 Stainless. 410 has a high heat retention which it makes it more difficult to heat treat. 410 needs to be treated very carefully while being hardened, heat treated or you will burn the metal and it will become brittle or lose its rust resistance. When you do heat treat the metal, the .032 had a 45 degree angle bend without losing its form and was comparable to 14 gauge in toughness. I also place these pieces in a concentrated salt solution for a little over two days with no signs of rust at all. I do however would advise to lighlty oil this metal and keep it dry while storing it. As for the look, the steel has a nice blue tinge to it instead of the bright white look that 304 has. My scales are awaiting to be heat treated at Round Rock Heat Treating. Due to the large amount of scaling, I had them heated professionall in a vaccum kiln to reduce the clean up. Frankly I just could not see myself cleaning up 827 scales. I am hoping to get them today and begin putting the scale shirt together pretty quick.
