Iipropati ze-S32304 zezinto eziphathekayo
I-UNS S32304 yeyomgangatho waseMelika wentsimbi yenqanaba elimbini, umgangatho wokuphunyezwa: ASTM A240/A270M-2017
I-UNS S32304 i-alloy yintsimbi ye-duplex engenasici equkethe i-23% yechromium kunye ne-4% ye-nickel.Iimpawu zokumelana ne-corrosion ye-2304 alloy zifana nezo ze-316L.Ukongezelela, iimpawu zayo zomatshini, amandla okuvelisa, ziphindwe kabini kwi-304L / 316L amabakala austenitic.Olu phawu lwenza abaqulunqi banciphise ubunzima beemveliso xa beyila iimveliso, ngakumbi iinqanawa zoxinzelelo.
Le ngxubevange ilungele ukusetyenziswa kwiqondo lobushushu -50°C /+300°C (-58°F/572°F).Amaqondo obushushu asezantsi nawo angasetyenziswa phantsi kweemeko ezingqongqo (ingakumbi kwizakhiwo ezidityanisiweyo).Xa kuthelekiswa ne-304 kunye ne-316 austenite, i-alloy ye-2304 inokumelana noxinzelelo olunamandla ngenxa ye-microstructure yesigaba esimbini, umxholo we-nickel ophantsi kunye nomxholo ophezulu we-chromium.
I-S32304 iMimandla yeSicelo seMathiriyeli
I-2304 i-duplex yensimbi engenasici inezixhobo ezilungileyo zoomatshini kunye nezomzimba, ukuchasana noxinzelelo lwe-corrosion kunye nezinye iifom ze-corrosion kunye ne-weldability efanelekileyo, okwenza kube lula ukubuyisela i-austenitic stainless steel njenge-304, 304L, 316, 316L njalo njalo.Ingasetyenziselwa ukuveliswa kwezixhobo zokubuyisela i-amine, izixhobo zokuvundiswa kwee-hydrocarbons, njl. Ukongeza, inokusetyenziswa njengabatshintshisi bobushushu kushishino lokuvelisa, ii-digester preheaters kwi-pulp kunye nephepha kushishino lwephepha, kunye neefreyimu zezihlalo zokuqeqesha kumanzi. ubushushu kunye neendawo ezingaselunxwemeni.
1.Imimandla emininzi esetyenziswa ngu-304 kunye no-316
2.Ishishini le-Pulp kunye nephepha (iitshiphu, iitanki zokugcina iitshiphu, iitanki zolwelo ezimnyama okanye ezimhlophe, izihluzi)
3. Isisombululo se-Caustic, i-asidi ephilayo (i-anti-SCC)
4. ishishini lokutya
5. Iinqanawa zoxinzelelo (ukunciphisa ubunzima)
6. Ukwembiwa kwemigodi (i-abrasive/corrosion)
