Abstract

In a process for the production of steel alloys, one or more elements capable of producing precipitation hardening such as titanium, copper, tungsten, molybdenum or boron are added to a carbon steel containing 0.1-0.4 per cent of carbon and 0-5 of silicon, cobalt or vanadium or both in an amount of 1-25 per cent being also added to the alloy. The hardening is produced by cooling the alloys quickly or slowly from 700-1300 DEG C. and then reheating to 250-700 DEG C. or by heating the alloys to 700-1300 DEG C. and then cooling very slowly. The titanium content of the alloy may be up to 10 per cent, copper up to 5, tungsten up to 30, molybdenum up to 30 and boron up to 4 and the iron content must be at least 25 per cent. In an example, an alloy containing 0.22 per cent of carbon, 0.27 of silicon, 0.58 of manganese, 17.7 of tungsten, 24 of cobalt, 1.7 of vanadium and 1.4 of titanium was cooled from 1250 DEG C. and reheated to 600 DEG C.
