Izinto ezibonakalayo ze-S32304
I-UNS S32304 ingeyensimbi ejwayelekile yaseMelika enezigaba ezimbili, izinga lokuqalisa: ASTM A240/A270M-2017
I-UNS S32304 ingxubevange iyinsimbi engagqwali eyiduplex ehlanganisa u-23% we-chromium kanye ne-nickel engu-4%.Izakhiwo zokumelana nokugqwala kwe-2304 alloy zifana nalezo ze-316L.Ngaphezu kwalokho, izakhiwo zayo zemishini, amandla okukhiqiza, ziphindwe kabili kunama-304L/316L amamaki austenitic.Lesi sici senza abaklami banciphise isisindo semikhiqizo lapho beklama imikhiqizo, ikakhulukazi imikhumbi yokucindezela.
Le alloy ifaneleka ikakhulukazi ukusetshenziswa ebangeni lokushisa elingu-50°C /+300°C (-58°F/572°F).Amazinga okushisa aphansi angasetshenziswa ngaphansi kwezimo ezilinganiselwe (ikakhulukazi ezakhiweni ezishiselwe).Uma kuqhathaniswa ne-304 kanye ne-316 austenite, i-alloy engu-2304 inokumelana nokugqwala kwengcindezi okuqinile ngenxa ye-microstructure yayo yezigaba ezimbili, okuqukethwe kwe-nickel ephansi nokuqukethwe okuphezulu kwe-chromium.
I-S32304 Material Application Areas
I-2304 duplex insimbi engagqwali inezakhiwo ezinhle zemishini nezomzimba, ukumelana nokugqwala kwengcindezi nezinye izinhlobo zokugqwala kanye nokushisela okuhle, okwenza kube nokwenzeka ukufaka esikhundleni sensimbi engagqwali ye-austenitic efana ne-304, 304L, 316, 316L njalonjalo.Ingasetshenziswa ekukhiqizeni imishini yokubuyisela i-amine, okokusebenza kokuvutshelwa kwama-hydrocarbons, njll. Ngaphezu kwalokho, ingasetshenziswa futhi njengezishintshisi zokushisa embonini yokukhiqiza, ama-digester preheaters embonini ye-pulp nephepha, kanye namafreyimu wezihlalo zokuqeqesha endaweni enomswakama. ukushisa nezindawo ezingasogwini.
1.Izinkambu eziningi ezisetshenziswa ngu-304 kanye no-316
2.Imboni ye-Pulp nephepha (ama-chips, amathangi okugcina ama-chip, amathangi aketshezi amnyama noma amhlophe, izihlungi)
3. Isixazululo se-Caustic, i-organic acid (anti-SCC)
4. imboni yokudla
5. Imikhumbi Yokucindezela (ukunciphisa isisindo)
6. Ukumba izimayini (okulimazayo/ukugqwala)
