超级奥氏体不锈钢UNS08367的焊接性能

摘要

The super austenitic stainless steel is widely used due to its excellent resistance to chlorine ion corrosion in recent years. Through all weld metal tensile test of the USN08367 and impact test of welding seam and heat affected zone, the influence of welding on the mechanic performance of USN08367 is analyzed; Through the welding seam of the UNS08367 and heat affected zone welding state and solid fusion processing state resistance to pitting and crevice corrosion test, the welding effect on the corrosion resistance performance of UNS08367 is analyzed.%近年来,超级奥氏体不锈钢凭借其优异的耐CL-腐蚀性能被广泛应用.文章通过对UNS08367全焊缝金属的拉伸试验以及对焊缝及热影响区的冲击试验,分析焊接对UNS08367力学性能的影响;通过对UNS08367焊缝及热影响区焊态以及固熔处理态耐点蚀和耐缝隙腐蚀试验,分析焊接对UNS08367耐腐蚀性能的影响.
