Abstract

PURPOSE: To prevent the local deformation of a steel for a wheel of a car at HAZ due to working after welding the steel by providing a specified relation between the tensile strength and the carbon equiv. of the steel.
CONSTITUTION: A high strength steel for a wheel of a car contg. 0.02W0.15% C, ≤2.0% Si and 0.1W2.0% Mn is regulated so as to satisfy the relation of TS≤25+ 100- carbon equiv. between the carbon equiv. represented by carbon equiv. =C+ Si/24+Mn/6 and the tensile strenght TS (kg/mm2). To the steel may be added 0.05W0.05% Nb. At this time, the steel is regulated so as to satisfy the relation of TS≤25+100- carbon equiv. +250-Nb between the carbon equiv. and the TS. Thus, a high strength steel causing no local deformation at HAZ during working after welding, and preventing deterioration in the fatigue resistance due to the softening of HAZ is obtd.
