“ＰＵ－１”低合金高强度抗Ｈ２Ｓ应力腐蚀钻材钢具有良好的综合力学性能和抗Ｈ２Ｓ应力腐蚀性能。对“ＰＵ－１”钢和焊缝合金断裂行为的研究结果表明，“ＰＵ－１”钻材钢抗Ｈ２Ｓ应力腐蚀性能和焊接性能较好，应用于结构钢构件具有显著的经济和社会效益。
“PU-1” low-alloy high-strength H2S stress corrosion resistant drilling steel has good mechanical properties and resistance to H2S stress corrosion. The results of research on fracture behavior of “PU-1” steel and weld alloy show that “PU-1” steel has better resistance to H2S stress corrosion and welding performance, and has obvious economic and social benefits for structural steel components.
