A401 spring steel

Featured Replies

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"

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.....:D

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.  

Hi ID,

I found these:

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 :)
