在某公司运盐敞车的设计制造中,为防止氯化物对车体的腐蚀,车体与盐接触部分采用了双相不锈钢2205。2205双相不锈钢由于其良好的抗点蚀及应力腐蚀性能,以及较好的力学性能及焊接性能,目前在石油天然气开发、油气储运、炼油化工和海洋工程等领域应用较多。为此,文中对2205双相不锈钢的焊接工艺进
In the design and manufacture of a company’s salt gondola, in order to prevent chloride corrosion on the body, the contact part of the body and the salt adopts duplex stainless steel 2205.2205 duplex stainless steel due to its good resistance to pitting and stress corrosion, As well as better mechanical properties and welding performance, at present in the oil and gas development, oil and gas storage and transportation, refining and chemical and marine engineering and other fields more applications. To this end, the text of 2205 duplex stainless steel welding process into
