Abstract

1425738 Heat-treating alloy steel SUMITOMO METAL INDUSTRIES Ltd 25 May 1973 [26 May 1972] 25303/73 Heading C7A Steel containing in percentage by wt. is austenitized and then quenched into a bath maintained at M 5 Œ 100‹C, the time and temperature of quenching being such that a bainite structure is obtained. The steel may then be tempered below the Ac 1 temperature. Optionally the steel also contains one or more of Quenching may be carried out in molten metal or salt. The steel may be used for high strength bolts or for concrete reinforcing rods.
