Abstract
High-carbon martensitic stainless steel containing less than 1.4% of carbon and less than carbon and chromium is first heated to a temperature 50 DEG to 150 DEG C. above the lowest temperature to which the steel must be heated to produce the maximum as-quenched hardness, the former temperature being not less than 1125 DEG C. The steel is then cooled to room temperature or below, and finally reheated to a temperature between 400 DEG and 700 DEG C. Sub-zero cooling may be to a temperature between -50 DEG and -80 DEG C. The method is particularly applied to a steel containing 0.8 to 1.1% carbon, 12.5 to 14.5% of chromium, and one or more of sulphur, phosphorus, manganese, silicon, vanadium, molybdenum, tungsten, antimony, nitrogen, cobalt, nickel, aluminium or titanium in a total amount less than 2.5%.
