SoCal Dave Posted October 11, 2016 Share Posted October 11, 2016 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. Quote Link to comment Share on other sites More sharing options...
Gergely Posted October 11, 2016 Share Posted October 11, 2016 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 Quote Link to comment Share on other sites More sharing options...
