Development of High-strength Fatigue Resistant and Atmospheric Corrosion Resistant Steel for Heavy-duty Railway Wagons
The chemical composition and hot rolling process of high-strength fatigue resistant and atmospheric corrosion resistant steel were introduced in this paper.The results of large-scale production show that the chemical composition and hot rolling process design of the developed high strength anti-fatigue and anti-atmospheric corrosion steel are reasonable,with high purity,high strength,high toughness,good atmospheric corrosion resistance,excellent forming,welding properties and fatigue resistance,which can better ensure the safe service of heavy-duty railway wagons.
