摘要
回顾了我国输气管线用控制轧制微合金钢的发展。通过研制新钢种的实验室数据和显微组织照片 ,全面地介绍了我国在 2 1世纪开始应用的现代化输气管线用针状铁素体钢 。
s:The development of controlled rolling micro-alloy steel for China gas pipeline is reviewed. Through the researched new kind steel laboratory data and its microstructure picture, the article describes the application of spinal ferrite steel on modern gas pipeline at the beginning of 21 century, also the related ductility fracture anti-crack toughness of the gas pipe steel application is discussed.
