通过弯梁裂纹应力腐蚀试验（CBB试验）和A262E晶间腐蚀试验，研究了钼对敏化不锈钢在高温充氧水中应力腐蚀敏感性的影响。钼的加入改善了敏化不锈钢在含氧高温水中的SCC敏感性，不仅通过延迟在较低温度下的敏化作用，而且通过在给定的敏化程度下增加材料对SCC的耐受性。实验室试验结果表明，钼的加入对改善不锈钢管道焊接接头在沸水堆环境中的应力腐蚀开裂敏感性是十分有益的。
The effect of molybdenum addition on the SCC susceptibility of sensitized stainless steel in oxygenated high temperature water has been studied through the creviced bent beam SCC test (CBB test) and A262E intergranular corrosion test. The molybdenum addition improved the SCC susceptibility of sensitized stainless steels in oxygenated high temperature water not only by delaying the sensitization at lower temperatures but also by increasing the material resistance to the SCC under a given degree of sensitization. These laboratory test results reveal that the molybdenum addition is quite beneficial for improving the SCC susceptibility of stainless steel pipe weld joints in boiling water reactor environment.
