Abstract With a view to utilizing certain iron ores contaminating with copper, a cop-per-containing low alloy rail steel (WP2) has been developed by Wuhan Ironand Steel Company. Such a rail steel containing 1% Si has been adopted forour own design of rails of grade 45 kg/m. It possesses high strength (σ_b≥92kg/mm~2) and hardness (on rail top≥280HB) with satisfactory toughness andplasticity as well as good resistance to wear and to atmospheric corrosion. Thiskind of rail may be used without quenching. Long-time railway running testsshowed that such a rail (WP2) performs well against wear and impact, exhibi-ting little corrosion at rail waist and bottom. It has been used not only inChinese railwavs but also in the Tanzania-Zambia railway in Africa.
