'''铁素体不锈钢'''（400系）含铬量在15%~30%，具有体心立方晶体结构。这类钢一般不含镍，有时还含有少量的Mo、Ti、Nb等元素，这类钢具有导热系数大，膨胀系数小、抗氧化性好、抗应力腐蚀优良等特点，多用于制造耐大气、水蒸气、水及氧化性酸腐蚀的零部件。铁素体不锈钢价格不仅相对低且稳定，并且具有许多独特的特点和优势，业已证明，在许多原先认为只能采用奥氏体不锈钢（300系）的应用领域，铁素体不锈钢是一种极为优异的替代材料，铁素体不锈钢不含镍，主要元素为铬（>10%）和铁，铬是不锈钢特别耐腐蚀的元素，其价格相对稳定。<ref>[https://www.163.com/dy/article/G5HBKJIC0538B08Z.html 铁素体不锈钢特殊的“王牌”]网易订阅</ref>
