Abstract
PURPOSE: To enhance free-cutting property and rolling fatique strength of the titled steel obtained by limiting a Te/S ratio in steel with a specific composition containing C, Si, Mn, S, Cr, Te, O.
CONSTITUTION: This high carbon steel for a free cutting bearing has a composition containing 0.80W1.20% c, 0.05W1.0% Si, 0.20W1.50% Mn, 0.020W0.040% S, 0.8W2.0% Cr, 0.002W0.020% Te below 0.0012% O, further, according to necessity, 0.05W0.50% Mo and comprising the remainder of Fe and inevitable impurities and a Te/S ratio thereof is limited to 0.1W1.0. That is, said steel is one wherein MnS is made spherical by adjusting S-Te-O and rolling life and free-cutting property are enhanced.
