I-904l yensimbi engenasici ye-Stainless Plate yintsimbi ye-superaustenitic eyenziwe nge-moderate ukuya kwi-corrosion resistance resistance kwindawo ebanzi.Umxube we-chromium kunye nomxholo we-nickel, kunye nezongezelelo ze-molybdenum kunye nobhedu zibonelela ngokugqwesa ukugqwala.Ngenxa ye-nickel 25% kunye ne-molybdenum 4.5%, i-ASTM B625 UNS N08904 inika i-chloride efanelekileyo yoxinzelelo lwe-corrosion ukuchasana nokuqhekeka, ukugoba kunye nokumelana nokunyuka kwe-corrosion jikelele. ukuya kwi-316L kunye ne-317L.Iphuhliswa kwiindawo eziqhekezayo eziqulethe iiasidi zesulfuric ezixubileyo.I-904l ipleyiti yensimbi engenasici inokumelana kakuhle neeasidi ze-inorganic ezifana ne-asidi ye-phosphoric eshushu.Inokudityaniswa ngokulula kwaye iqhutywe yinkqubo yokwenziwa kwemigangatho.Ipleyiti ye-ss 904l idukile kwaye inokwakheka lula.Ukongezwa kwe-molybdenum kunye ne-nitrogen kunika izixhobo zokusebenza ezinamandla ngakumbi kwaye kunokuba yimfuneko xa kuthelekiswa nomgangatho we-304/304L amabakala.I-astm a240 uhlobo lwe-904l lunokuchasana okugqwesileyo kumanzi olwandle afudumeleyo kunye nokuhlaselwa kwe-chloride.Ukumelana okuphezulu kwayo kuchasene noxinzelelo lwe-corrosion cracking kwaye kungenxa yobukho bexabiso eliphezulu le-nickel ekubunjweni kwayo.Ngaphezu koko, ukongezwa kobhedu kuphuhlisa ukuchasana ne-asidi ye-sulfuric kunye nezinye ii-agent zokunciphisa kwiimeko ezinobundlobongela kunye nezithambileyo.Nangona kunjalo, ukuzinza kolwakhiwo lweli bakala kuwela kumaqondo aphezulu, ngokukodwa ngaphezu kwe-400 ° C.ASTM A240 UNS N08904 impahla ingaba isisombululo sokushisa kwi-1090 ukuya kwi-1175 ° C ngokulandela indlela yokupholisa ngokukhawuleza.Unyango lwe-thermal lufanelekile ukuqiniswa.Iphepha le-1.4539 izicelo eziphambili zizixhobo zokucoca i-oyile, i-Pulp kunye namashishini okucubungula amaphepha, izityalo zokucoca igesi, njl.
