Abstract
A low-alloy high-speed steel containing, in percent by weight, 0.90-1.05 % C, 0.10-1.00 % Si, 2.0-4.5 % Cr, 4.0-6.0 % Mo, 1.0- 2.0 % W, 1.0-2.0 % V, 1.0-6.0 % Co, 0.02-0.08 % N, and up to 0.060 % S. The remainder comprising iron and minor additions and contents of impurities normally occurring in steel. The addition of Co to the alloy permits rapid decomposition of the austenite phase and thereby allows an increase in the C/V ratio which, in term, gives improved performance in tool applications.
