Ipleyiti yentsimbi engagqwaliyo engama-904Lluhlobo lwentsimbi engagqwaliyo e-austenitic enomxholo ophantsi kakhulu wekhabhoni kunye ne-alloying ephezulu eyenzelwe iindawo ezineemeko ezinzima zokubola. Inokumelana nokubola okungcono kune316Lkwaye317L, ngelixa kuthathelwa ingqalelo ixabiso, ukusebenza, kunye nokusebenza kakuhle kweendleko. iphezulu. Ngenxa yokongezwa kwe-1.5% yobhedu, inokumelana okuhle kokubola ngokuchasene nokunciphisa ii-asidi ezifana ne-sulfuric acid kunye ne-phosphoric acid. Ikwanakho ukumelana okuhle kokubola ngokuchasene noxinzelelo lwe-corrosion pitting kunye ne-crevice corrosion ebangelwa yi-ions ze-chloride, kwaye inokumelana okuhle nokubola phakathi kwe-granular. Kwi-asidi ye-sulfuric ecocekileyo kuluhlu loxinzelelo lwe-0-98%, ubushushu benkonzo yepleyiti yentsimbi ye-904L bunokuba phezulu ukuya kuma-40 degrees Celsius. Kwi-asidi ye-phosphoric ecocekileyo kuluhlu loxinzelelo lwe-0-85%, ukumelana kwayo nokubola kulungile kakhulu. Kwi-asidi ye-phosphoric yemizi-mveliso eveliswa ziinkqubo ezimanzi, ukungcola kunempembelelo enamandla ekumelaneni nokubola. Phakathi kwazo zonke iintlobo ze-asidi ye-phosphoric, i-904L super austenitic stainless steel inokumelana okungcono kokubola kunentsimbi eqhelekileyo engagqwali. Kwii-asidi ze-oxidizing ezinamandla, i-904L stainless steel inokumelana okuphantsi kokubola kuneentlobo ezahlukeneyo zentsimbi exutyiweyo kakhulu. ngaphakathi kolu luhlu loxinzelelo. Ukumelana nokubola kwentsimbi ye-904L kungcono kunokwentsimbi eqhelekileyo engagqwali. Intsimbi engagqwaliyo ye-904L inokumelana okuphezulu nokugqwala kwemingxuma. Imelana nokugqwala kwemingxuma kwizisombululo ze-chloride. Amandla ayo alungile kakhulu. Umxholo ophezulu we-nickel weIpleyiti yentsimbi ye-904Linciphisa izinga lokugqwala kwimingxuma nakwii-seams. Ngenxa yomxholo wayo ophezulu we-nickel, i-904L inokumelana okuphezulu nokuqhekeka kokugqwala okuxineneyo kwizisombululo ze-nitride, izisombululo ze-hydroxide ezixineneyo kunye neendawo ezityebileyo ze-hydrogen sulfide.
