Abstract

PURPOSE: To obtain the titled low alloy steel capable of being carburized in a short time by adding a relatively large amount of Mn and an adequate amount of Cr and/or Mo to a low C low alloy steel.
CONSTITUTION: The Si content of a low alloy steel contg. <0.1wt% C is lowered to ≤0.4%, and to the steel are added 0.15W1.2wt% Mn and ≤1wt% Cr and/or ≤0.4wt% Mo while adjusting the components so that the following condition is satisfied: 1/3Mn(%)+1/3Cr(%)+Mo(%)≥0.25%. ≤0.1wt% Al and/or ≤0.01wt% B may be added to enhance the cold workability, core hardenability, etc.
