沉淀硬化不銹鋼，在各類不銹鋼中通過單獨或復合加入硬化元素，而獲得高強度、高韌性、高耐蝕性的一類不銹鋼

分類

根據鋼中主要合金元素的含量和所加的硬化元素而分為四大類，即：

(1)馬氏體沉淀硬化不銹鋼，含碳一般低0.1%。通過加入硬化元素(銅，鋁，鈦和鋁等)進行強化，以彌補強度不足。鉻含量一般高于17%，并加入適量鎳以改善耐蝕性；

(2)馬氏體時效不銹鋼，含碳不高于0.03%以保證馬氏體基體的韌性、耐蝕性、焊接性和加工性，含鉻不少12%以確保耐蝕性。另外還加入合金元素鉆，進一步改善鋼的熱處理；

(3)半奧氏體型，即過渡型沉淀硬化不銹鋼，含鉻不少于12%。含碳低，并且以鋁作為其主要沉淀硬化元素這類型鋼比馬氏體沉淀硬化不銹鋼有更好的綜合性能；

(4)奧氏體沉淀硬化不銹鋼，是在淬火狀態和時效狀態都為穩定奧氏體組織的不銹鋼，含鎳(高于25%)和錳都高，含鉻高于13%，以確保良好的耐蝕性和性通常添加鈦、鋁、釩或磷作為沉淀硬化元素，同時加人微量硼、釩、氮等元素，以獲得優良的綜合性能

特點

沉淀硬化不銹鋼具有高強度、高韌性、高耐蝕性、高性和優良的成型性、焊接性等綜合性能。
