Abstract

1315203 Chromium steels SOC ANON FONDERIES MAGOTTEAUX 23 April 1970 [30 April 1969] 19549/70 Addition to 1218981 Heading C7A A cast alloy steel contains Cr and C within the area covered by zones 0, 1, 2, 3 and 4 in the drawing, the balance being Fe, impurities and, optionally one or more incidental ingredients which are used in the production of cast alloy steels. The steel is subjected to a heat treatment comprising hardening from a temperature in the range 950‹C. to 1200‹C. followed by tempering at a temperature in the range 440‹C. to 570‹C., the heat treatment being such that the resulting alloy steel has a metallographic structure constituted by a martensitic solid solution free from pearlite, and containing eutectic and pro-eutectoid carbide and less than 5% residual austenite. The impurities may include Mn, Si, S and P and the incidental ingredients Mo, V and W. Particular heat treatments are specified for alloys within each of the zones shown in the drawing. The alloys are suitable for uses requiring abrasion and impact shock resistance such as balls and lining plate for crushers and grinders.
