Abstract

A high strength steel, which is especially suitable for chromizing, comprises:- C 0À05-0À2% Al 0À1-0À3% Cr 0À5-2% Mn 1-1À5% Mo 0À4-2% Si 0À2-1% Ti 0À15-0À5% V 0À2-1% with optional Ni and/or Co 0À1-1À5% in total additions of Cu 0À05-0À75%, the balance being iron. The steel may be quenched in oil from 1000 C. and tempered at 100-600 C. and may be cold worked even after chromizing which is carried out by heating the steel in contact with a chromium halide for 2-20 hours at 900-1100 C.
