Abstract

PURPOSE: To provide tough, wear resistant steel excellent in wear resistance and toughness, and useful for making construction machine etc., by heating at a specific rate a steel contg. specific amounts of C, Si, Mn, and Cr to harden it, then by tempering it.
CONSTITUTION: A steel comprising 0.5W1.2% C, 0.7W1.7% Si, 0.3W1.0% Mn, 0.3W2.0% Cr, the balance being Fe, is heated at a rate of 10W200°C/min. to a temp. 750W950°C, and is kept at the temp. for max. 30 min. to harden the steel, then it is tempered to produce tough, wear resistant steel having martensite and carbide in its structure.
