Abstract

1,161,844. Alloy steels. ENGLISH STEEL CORP. Ltd. June 14, 1968 [June 29, 1967], No.30166/67. Heading C7A. A heat resistant alloy steel consists, by weight, of C 0À2-0À3% Si < 0À3% Mn 0À4-1 % Ni 0À4-1% Cr 0À7-1À4% Mo 0À5-1À5% V 0À25-0À4% Nb 0À03-0À15% B 0À002-0À1% Fe Balance (except for impurities and incidental constituents). Preferably P and S should each not exceed 0À04%. The steel may be austenitized at 950‹ -980‹ C., cooled in air, steam, water-mist or oil, and then tempered at 650‹ -720‹ C. It is suitable for the manufacture of large forgings for steam turbine rotors.
