ABSTRACT:
A hot work tool steel has high hardness capability and improved toughness when air cooled in section sizes of 6 inches (15.24 cm) or larger. The alloy steel which is deep air hardenable, has good dimensional stability and exceptional wear resistance, in its broad scope consists essentially of about 0.35-0.6 w/o carbon, 1.0 w/o max. manganese, 2.0 w/o max. silicon, 5.7-7.0 w/o chromium, 1.65-2.2 w/o molybdenum, 0.6-1.1 w/o vanadium, and the balance is iron except for the usual impurities found in commercial grades of such alloy steels.
