Abstract

A method of producing a high speed steel alloy containing, in percent by weight (wt.%): C 1.00-1.10, N 0.005-0.025, Cr 3.80-4.40, Mo 3.90-4.50, W 0-1.0, Co 0-0.99, V 1.8-2. 2, Nb 0-0.30, Mn 0.20-0.40, Si 1.40-1.55, Ni 0-0.50, and Cu 0-0.50, the balance being Fe and normally occurring impurities, and wherein said method comprises the following steps: providing a melt of said alloy, casting said melt followed by solidification thereof, hot forming the alloy into a predetermined body, soft annealing the solidified alloy, and hardening said body of the alloy at a hardening temperature T in the range of 1100°C-1200°C for a predetermined time t which is in the range of t1-t2, wherein t1 is a time which is sufficient for carbide-forming elements of the alloy to be dissolved in an austenitic structure presented by the alloy. Maximum hardening time t2 is below a time at which a medium austenite grain size of the alloy, as measured with the Snyder-Graff method, is such that the Snyder-Graff intercept grain size number (SG) is at least 13.
