Abstract

PURPOSE: To provide high strength to a low alloy steel contg. a specified amt. of C, Si, Mn, Cr, Mo and V without losing the dimensional accuracy by cold working the steel in a soln.-heat-treated state followed by age hardening at a specified temp.
CONSTITUTION: A low alloy steel consisting of, by wt., C 0.05W0.25%, Si≤0.5%, Mn≤2.0%, Cr 0.30W2.0%, Mo 0.50W2.0%, V 0.10W0.50% and the balance Fe essentially is soln.-heat-treated, cold worked by 20% or more, and age-hardened at a temp. below 400°C at which the cold work hardening is not eliminated. Thus, the cols work hardening and the age hardening are superposed without losing the dimensional accuracy. This steel is suitable for use in manufacture of high strength machine parts.
