hotrodiesel Posted December 21, 2008 Share Posted December 21, 2008 I know I've read somewhere but can't remember. Can someone tell me what the letter and number in steel stands for? like H-13, S-7, etc. What do these mean? Thanks! Quote Link to comment Share on other sites More sharing options...

Woody Posted December 21, 2008 Share Posted December 21, 2008 ASI Code Type of Steel A Air hardening D Die Steel F Carbon/Tungsten H Hot work alloys L Low alloy M Molybdenum O Oil hardening P Casting Steel S Shock resistant T Tungsten W Water hardening The number then refers to the specific composition of the alloy.
