铁素体不锈钢作为具有良好装饰性的耐腐蚀材料和具有良好高温性能的耐热材料,广泛用于建筑、厨房和汽车等方面。此外,钢中不含稀有元素Ni,不易产生应力腐蚀裂纹(SCC)的这一特点,也受到人们的关注,使其应用范围不断扩大。另一方面,由于传统的铁素体不锈钢与奥氏体不锈钢相比延伸率 Ferritic stainless steels are widely used in construction, kitchens and automobiles as well as corrosion-resistant materials with good decorative properties and heat-resistant materials with good high-temperature properties. In addition, the steel does not contain rare elements Ni, not easy to produce stress corrosion cracking (SCC) this feature has also been the concern that its scope of application continues to expand. On the other hand, due to the elongation of traditional ferritic stainless steels compared to austenitic stainless steels
