铁素体不锈钢在使用状态下以铁素体组织为主的不锈钢。含铬量在11％~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等到元素，这类钢具导热系数大，膨胀系数小、抗yang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。这类钢存在塑性差、焊后塑性和耐蚀性明显降低等缺点，因而限制了它的应用。炉外精炼技术（AOD或VOD）的应用可使碳、氮等间隙元素大大降低，因此使这类钢获得广泛应用。

  奥氏体——铁素体双相不锈钢是奥氏体和铁素体组织各约占一半的不锈钢。在含C较低的情况下，Cr含量在18％~28％，Ni含量在3％~10％。有些钢还含有Mo、Cu、Si、Nb、Ti，N等合金元素。该类钢兼有奥氏体和铁素体不锈钢的特点，与铁素体相比，塑性、韧性更高，无室温脆性，耐晶间腐蚀性能和焊接性能均显著提高，同时还保持有铁素体不锈钢的475℃脆性以及导热系数高，具有超塑性等特点。与奥氏体不锈钢相比，强度高且耐晶间腐蚀和耐氯化物应力腐蚀有明显提高。双相不锈钢具有优良的耐孔蚀性能，也是一种节镍不锈钢。

  马氏体不锈钢通过热处理可以调整其力学性能的不锈钢，通俗地说，是一类可硬化的不锈钢。典型牌号为Cr13型，如2Cr13,3Cr13,4Cr13等。粹火后硬度较高，不同回火温度具有不同强韧性组合，主要用于蒸汽轮机叶片、餐具、外科手术器械。根据化学成分的差异，马氏体不锈钢可分为马氏体铬钢和马氏体铬镍钢两类。根据组织和强化机理的不同，还可分为马氏体不锈钢、马氏体和半奥氏体（或半马氏体）沉淀硬化不锈钢以及马氏体时效不锈钢等。

 对于产品的检验，知道产品的来源和组织性能是无损检测 的手段，也是NDT从业者的创新。

成分组成在18-8型不锈钢的成分基础上演变，主要有以下几方面的重要发展：

1) 加Mo改善点蚀和耐缝隙腐蚀

2) 降C或加Ti、Nb，减少晶间腐蚀倾向

3) 加Ni和Cr改善高温抗yang化性和强度

4) 加Ni改善抗应力腐蚀性能.

5) 加S、Se改善切削性和构件表面精度.
