S31683 00Cr18Ni14Mo2Cu2 不銹鋼主要(yao)特(te)性和用途

  此鋼(gang)(gang)(gang)相(xiang)當于降低了(le)0Cr18Ni12Mo2Cu2不(bu)銹(xiu)鋼(gang)(gang)(gang)中(zhong)(zhong)(zhong)的碳量(liang)以(yi)提高其焊后耐(nai)晶間腐(fu)蝕(shi)(shi)(shi)性(xing)能(neng)(neng)，提高了(le)0Cr18Ni12Mo2Cu2不(bu)銹(xiu)鋼(gang)(gang)(gang)中(zhong)(zhong)(zhong)的鎳(nie)量(liang)以(yi)獲(huo)得鋼(gang)(gang)(gang)的單一奧氏(shi)體(ti)組織。此鋼(gang)(gang)(gang)在(zai)硫(liu)酸(suan)、磷酸(suan)及(ji)有(you)機酸(suan)等介(jie)質中(zhong)(zhong)(zhong)具(ju)有(you)良好的耐(nai)蝕(shi)(shi)(shi)性(xing)和耐(nai)晶間腐(fu)蝕(shi)(shi)(shi)性(xing)能(neng)(neng)，尤其在(zai)稀、中(zhong)(zhong)(zhong)等濃度的硫(liu)酸(suan)介(jie)質中(zhong)(zhong)(zhong)具(ju)有(you)較(jiao)高的耐(nai)腐(fu)蝕(shi)(shi)(shi)性(xing)能(neng)(neng)。

  用于制造化工(gong)、化肥和(he)化纖等工(gong)業設備，如結(jie)構件(jian)、容(rong)器(qi)和(he)管道、零(ling)部件(jian)等。
