Abstract

A steel melt containing 0.001-0.03% B and 0.001-0.03% N is formed into an article which is then carburized and heat treated to give a casehardened article. In examples the steel is carburized at 930 DEG C. in an atmosphere of 50% N2 20% H2CO the remainder CH4 and CO2, oil quenched and annealed at 180 DEG C.
