铁素体不锈钢作为耐腐蚀性材料、耐热材料,广泛应用在建材、厨房、汽车等领域。尤其让人关注的是,它具有不含稀有元素Ni但也很少发生应力腐蚀裂纹(SCC)的优点,因此它的适用范围也更加广泛。但原有的铁素体不锈钢与奥氏体不锈钢相 Ferritic stainless steel as corrosion-resistant materials, heat-resistant materials, widely used in building materials, kitchen, automotive and other fields. Of particular concern is the fact that it has the advantage of being free of rare elemental Ni but rarely SCC, so its applicability is also wider. However, the original ferritic stainless steel and austenitic stainless steel phase
