METHOD FOR PRODUCING HIGH CARBON CHROMIUM BEARING STEEL

PROBLEM TO BE SOLVED: To provide a technique capable of highly suppressing huge carbides in spite of short time soaking. SOLUTION: In the method, a slab for high carbon chromium bearing steel is at least subjected to soaking and hot rolling, thus high carbon chromium bearing steel is produced. Also,...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a technique capable of highly suppressing huge carbides in spite of short time soaking. SOLUTION: In the method, a slab for high carbon chromium bearing steel is at least subjected to soaking and hot rolling, thus high carbon chromium bearing steel is produced. Also, in the method where the soaking temperature of 1,150 to 1,260°C is adopted, as the slab for high carbon chromium bearing steel, the one having a P concentration of 0.002 to 0.009 mass% is used, and the holding time of the soaking temperature is controlled to
