发明的详细说明本发明系耐腐蚀低合金钢的一个新方案,它在含硫化氢气体环境中的耐腐蚀性及焊接接头耐应力腐蚀破裂性能,均比试验所用的对比碳素钢和低合金钢有了改善。应力腐蚀破裂发生在含有硫化氢气体环境中,尤其在石油工业领域。即在含有硫化氢气体的油田、油罐等方面,历来使用的并管、阀门、螺栓、螺母等部件,易产生应力
DETAILED DESCRIPTION OF THE INVENTION The present invention is a new solution of corrosion-resistant low alloy steel, its corrosion resistance in the environment containing hydrogen sulfide gas and stress corrosion cracking resistance of welded joints, compared with the test used in contrast to carbon steel and low alloy Steel has improved. Stress corrosion cracking occurs in the environment containing hydrogen sulfide gas, especially in the oil industry. That is, hydrogen sulfide gas containing oil fields, oil tanks, etc., has always been used in the tube, valves, bolts, nuts and other components, prone to stress
