BUXIUGANGZHISHI


不锈钢(Stainless Steel)指耐空气、蒸汽、水等弱腐蚀介质和酸、碱、盐等化学浸蚀性介质腐蚀的钢,又称不锈耐酸钢。实际应用中,常将耐弱腐蚀介质腐蚀的钢称为不锈钢,而将耐化学介质腐蚀的钢称为耐酸钢。由于两者在化学成分上的差异,前者不一定耐化学介质腐蚀,而后者则一般均具有不锈性。不锈钢的耐蚀性取决于钢中所含的合金元素。宁波430不锈钢

马氏体不锈钢的常用牌号有1Cr13、3Cr13等,因含碳较高,故具有较高的强度、硬度和耐磨性,但耐蚀性稍差,用于力学性能要求较高、耐蚀性能要求一般的一些零件上,如弹簧、汽轮机叶片、水压机阀等。这类钢是在淬火、回火处理后使用的。宁波430不锈钢
