I did manage to find two data points for A2 in "Tool Steels", Roberts, Hamaker, Johnson. They give ultimate tensile strength (UTS) of 269,500 psi and 54HRC if tempered at 1000 F. And for tempering at 1100 F they give: 47HRC; UTS is 232,600 psi; yield strength is 184,000 psi; elongation is 5% and reduction of area is 13.9%.

Hi Ren,

Thank you very much for these data. I believe these are static data. I need dynamic yield strength (Yield strength measured at high strain rate).

Kind regards,
