摘要

PCT No. PCT/GB96/00034 Sec. 371 Date Sep. 29, 1997 Sec. 102(e) Date Sep. 29, 1997 PCT Filed Jan. 11, 1996 PCT Pub. No. WO96/22396 PCT Pub. Date Jul. 25, 1996A method of producing a wear and rolling contact fatigue resistant bainitic steel product whose microstructure is essentially carbide-free. The method comprises the steps of hot rolling a steel whose composition by weight includes from 0.05 to 0.50% carbon, from 1.00 to 3.00% silicon and/or aluminum, from 0.50 to 2.50% manganese, and from 0.25 to 2.50% chromium, balance iron and incidental impurities, and continuously cooling the steel from its rolling temperature naturally in air or by accelerated cooling.
