October 9, 20169 yr got some A401 SiCr spring steel in a hardened state and would like to know about treating it EN47 is the nearest grade I have been told dont know yet what I will use it for, it is in various diameters from 8mm - 5/16" to 16mm - 5/8"
October 11, 20169 yr If this is the consignment I think it is, I shall be most interested in all replies.....as I recon I have half a chance of scoring some from the same source.....
October 11, 20169 yr I am not familiar with the numbers for the spring steel you will get. Here in the U.S.A., Spring steel is use a lot for hand tool like punches or chisels. Some people normalize them and then heat treat them but others just shape them and use them. I usually get my spring steel from truck springs. Good luck.
October 11, 20169 yr Hi ID, I found these: http://optimumspring.com/technical_resources/materials/steel_alloys/chrome_silicon_401_spring_wire.aspx http://www.steelss.com/Carbon-steel/astm-a401.html Based on chemical composition I'd say it's not much for hot tools. Maybe drifts. As it quenches in water and C is 0,51-0,59 it can be hard enough for cold used chisels or punches. - Me think Bests: Gergely
