Abstract

PURPOSE: To improve the machinability of a low alloy steel, the emboss workability and the sectional uniformity of hardness due to heat treatment by adding a restricted amt. of C, Si, Mn, Cr, Mo, V, S, etc. to the steel.
CONSTITUTION: A low alloy steel contg. C 0.2W0.5%, Si≤2.0%, Mn≤2.0%, Cr 0.5W4.0%, Mo 0.03W2.0%, V 0.01W2.0% and S 0.036W0.15% or further contg. one or more out of Ni≤1.20%, Cu≤2.0%, Al≤0.50%, Zr≤0.50% and Ti≤0.50% and one or more out of Ca 0.0005W0.0100%, Pb 0.03W0.20%, Se 0.03W0.20%, Te 0.01W0.15% and Bi 0.01W0.20%. By this steel compsn. enhanced sectional uniformity of hardness due to heat treatment, machinability and emboss workability are provided, and the hardness level of the steel is maintained even in high temp. tempering. Accordingly, this steel is suitable for use as a material for a large-size metal mold.
