I'll also add a little info. about the letter designation for tool steels. W = Water Hardening Steels. O = Oil Hardening Steels. A = Air Hardening Steels. D = Die steels. L = Low alloy steels.
I know I left a few out such as S-7 but I will be adding more info. as I find it and time allows. The above chemistry levels are just a base to allow comparison. Actual percentages will vary from manufacturer to manufacturer. It will probably even vary slightly from batch/smelt to batch/smelt from the same manufacturer.
