摘要:
针对奥氏体不锈钢无缝钢管通过硫酸-硫酸铜法进行晶间腐蚀试验时,ASTM A262、NB/T 20004和GB/T 4334三个标准中对实验要求的差异进行探讨,主要从试样制备、敏化热处理制度、腐蚀试验和评定试验4个方面进行了分析对比,结果显示这三个标准之间存在着明显的差异,表明三个标准下硫酸-硫酸铜法晶间腐蚀试验之间没有必然的替代性,因此在一定程度上说明:不同材料体系中的奥氏体不锈钢无缝钢管,在进行晶间腐蚀试验时应按照相应的标准规定进行。
Abstract:
In this paper, the differences of intergranular corrosion test requirements using copper sulfatesulfuric acid test method in ASTM A262, NB/T 20004 and GB/T 4334 three standards were analyzed, and the conclusions were got through comparing from four aspects including specimen preparation, sensitization heat treatment, corrosion test and evaluation, it was concluded that the three standards are different, and there are no substitution among these standards. So to a certain extent, for austenitic seamless stainless steel pipe in different material systems, the intergranular corrosion test should be performed in accordance with the corresponding standard stipulated in the relative material procurement specifications.
