Abstract
1,207,643. Carburized steel. FAGERSTA BRUKS A.B. June 2, 1969 [June 14, 1968], No.27763/69. Heading C7A. A steel consisting, by weight, of C 0À01 - 0À04% Mn 2À2 - 6% Si 0À5 - 2% Al (acid sol.) up to 0À2% Nb, Ta and/or V 0À01 - 0À5% N up to 0À03% Zr up to 0À2% Fe and impurities - balance, is carburized. The carburized layer has a C content of 0À5 - 1À5%. After carburizing, the product may be hardened and tempered. Uses. Rods, bars, tubes, gear wheels and rock drill bits.
