摘要
综合阐述了管线钢的强度、韧性、应力腐蚀开裂、氢致裂纹、焊接性能的发展提高过程。指出合金成份设计、冶金技术和控扎控冷工艺三者之间的最佳结合是决定管线钢综合性能的根本，同时提出了我国管线钢发展应该努力的方向。
The article summarizes the development upgrade process of strength, toughness, stress corrosion cracks, hydrogen induced cracks and welding properties of pipe line steel. And point out the best combination among alloy composition design, metallurgical technology and control rolling and control cooling process is the basis to decide the comprehensive properties of pipe line steel. Meanwhile, the author puts forward China pipe line steel's development direction which shall try to get.
