Ipleyiti yentsimbi engama-904luhlobo lwe-austenitic stainless steel kunye nomxholo wekhabhoni ophantsi kakhulu kunye ne-alloying ephezulu eyenzelwe iindawo ezineemeko ezinzima zokubola. Inokumelana ne-corrosion engcono kune-316L kunye ne-317L, ngelixa ithathela ingqalelo zombini ixabiso kunye nokusebenza. Ixabiso elihle lemali. Ngenxa yokongezwa kwe-1.5% yobhedu, inokumelana ne-corrosion egqwesileyo ekunciphiseni i-acids efana ne-sulfuric acid kunye ne-phosphoric acid. Ikwanayo nokumelana ne-corrosion egqwesileyo ngokuchasene noxinzelelo lwe-corrosion, i-pitting kunye ne-crevice corrosion ebangelwa ii-ion eziyinkimbinkimbi, kwaye inokumelana kakuhle ne-intergranular corrosion. Kwi-asidi ye-sulfuric ecocekileyo kwi-concentration range ye-0-98%, ubushushu benkonzo ye-904L yeplate yensimbi ingaba phezulu kwi-40 degrees Fahrenheit.
Kwi-asidi ecocekileyo kwi-concentration range ye-0-85%, ukuxhathisa kwayo kwe-corrosion kuhle kakhulu. Kwimizi-mveliso ye-phosphoric acid eveliswa ziinkqubo ezimanzi, ukungcola kunempembelelo enamandla ekuxhathiseni ukubola. Phakathi kwazo zonke iintlobo ze-asidi, i-904L super austenitic steel stainless inokumelana nokugqwala okungcono kunentsimbi eqhelekileyo engenasici. Kwi-asidi ye-nitric ene-oxidizing kakhulu, i-904L yensimbi engenasici inokumelana ne-corrosion ephantsi kuneentsimbi ezixutywe kakhulu ezingenayo isilivere. Kwi-hydrochloric acid, ukusetyenziswa kweI-904L iipleyiti zensimbi ezingenasiciinqunyelwe kwiindawo ezisezantsi ze-1-2%.
