錳和氮可以代替鉻鎳不銹鋼中鎳，鉻鎳奧氏體鋼的優(yōu)點(diǎn)雖然很多，但近幾十年來由于鎳基耐熱合金與含鎳20％以下的熱強(qiáng)鋼的大量發(fā)展與應(yīng)用，以及化學(xué)工業(yè)日益發(fā)展對(duì)不銹鋼的需要量越來越大，而鎳的礦藏量較少且又集中分布在少數(shù)地區(qū)，因此在世界范圍內(nèi)出現(xiàn)了鎳在供和需方面的矛盾。所以在不銹鋼與許多其他合金領(lǐng)域（如大型鑄鍛件用鋼、工具鋼、熱強(qiáng)鋼等）中，特別是鎳的資源比較缺乏的國家，普遍地開展了節(jié)鎳和以其他元素代鎳的科學(xué)研究與生產(chǎn)實(shí)踐，在這方面研究和應(yīng)用比較多的是以錳和氮來代替不銹鋼與耐熱鋼中的鎳。
