内容提要:本研究以大生产条件为依据,通过两次正交试验,找出了影响1Cr_(18)Ni_9Ti冷拨(轧)无缝钢管晶间腐蚀的主要因素为圆溶温度,并按具体情况分别选出能满足钢管综合性能要求的最优工艺条件(其中成品道次和成品前一道次固溶温度分别为1040℃和1100℃)。该工艺条件经生产运用效果良好。最后从金相分析的角度映证了试
Abstract: In this study, based on large production conditions, two orthogonal experiments were conducted to find out the main factors affecting the intergranular corrosion of 1Cr_ (18) Ni_9Ti cold-drawn seamless steel tubes were round melting temperature, Conditions were selected to meet the comprehensive performance requirements of the steel pipe the best process conditions (including the finished pass and the finished product before a solution temperature of 1040 ℃ and 1100 ℃, respectively). The process conditions produced by the use of good results. Finally from the perspective of metallographic analysis of the test
