摘要
本文采用预裂纹试样研究了38CrNi3MoVA钢在3.5%(质量浓度)NaCl水溶液腐蚀介质中的应力腐蚀性能,并由此计算出材料的临界裂纹尺寸,由试验结果可知,该材料具有较好的抗3.5%(质量浓度)NaCl水溶液腐蚀性能和很高的使用可靠性。
The stress corrosion of 38CrNi3MoVA steel was studied with pre-cracking specimens in 3.5% NaCl solution,and the critical crack size of the material was thus figured out.The results show that 38CrNi3MoVA steel is resistant to stress corrosion in 3.5% NaCl solution and reliable in use.
