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.      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1977/V13/Iz1/23 No related articles found!
