摘要
为防止TP347材料焊缝晶界贫铬现象发生,要求对焊接接头进行稳定化热处理。在相同焊接工艺条件下,对TP347不锈钢管材焊接接头采用不同的稳定化热处理工艺,并取样进行力学性能试验和晶间腐蚀性能试验。对比分析实验结果,探讨不同工艺条件下各项试验指标的优劣,对适用于TP347不锈钢焊后稳定化热处理工艺提出指导性建议。
In order to avoid the phenomenon of grain boundary chromium depletion in weld metal of stainless steel TP347 ,often give a stabilization heat treatment to those welded joints. In this article,under the condition of the same welding process,adopt different stabilization heat treatment process to these welded joints of stainless steel TP347,and take coupons from these welded joints for mechanical properties test and intergranular corrosion test. Analyze the results of comparative tests under the different stabilization beat treatment processes,then give advice for stabilization heat treatment which suitable for stainless steel TP347.
