<p>A 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 aluminium, 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.</p> |
