I-2205 duplex insimbi engagqwali iyinsimbi engagqwali eyi-duplex eyakhiwe ngo-21% we-chromium, u-2.5% we-molybdenum no-4.5% we-nickel-nitrogen alloy. Izakhiwo ze-ferrite kanye ne-austenite zibalwa cishe ngama-50%. Inamandla aphezulu, ukuqina komthelela omuhle kanye nokumelana nokugqwala okuhle kwengcindezi yendawo yonke. Amandla okukhiqiza we-2205 duplex stainless steel aphindwe kabili kunawe-austenitic stainless steel. Lesi sici senza abaklami behlise isisindo lapho beklama imikhiqizo, okwenza le alloy ingabizi kakhulu kuno-316 no-317L. Le ngxubevange ifaneleka ngokukhethekile ebangeni lokushisa elingu-50°F/+600°F. Kuzinhlelo zokusebenza ezingaphezu kwalolu banga lokushisa, le alloy nayo ingacatshangelwa, kodwa kunemikhawulo ethile, ikakhulukazi uma isetshenziselwa izakhiwo ezishiselwe.
Uma kuqhathaniswa ne-316L kanye ne-317L austenitic stainless steel, i-2205 duplex stainless steel inokusebenza okuphakeme ekumelaneni nokugqwala komgodi kanye nokugqwala kokuqhekeka. Inokumelana nokugqwala okuphezulu. Uma kuqhathaniswa ne-austenitic, yayo I-coefficient yokwandisa okushisayo iphansi futhi ukuqhutshwa kokushisa kuphezulu. Uma kuqhathaniswa nensimbi engagqwali ye-austenitic, ingxube ye-duplex yensimbi engagqwali engu-2205 inamandla acindezelayo aphindwe kabili. Uma kuqhathaniswa ne-316L ne-317L, umklami anganciphisa isisindo sayo. Ingxubevange 2205 ifaneleka ngokukhethekile ebangeni lokushisa elingu -50°F/+600°F. Ngaphansi kwemikhawulo eqinile (ikakhulukazi ezakhiweni ezishiselwe), ingasetshenziswa futhi emazingeni okushisa aphansi.
Duplex insimbi engagqwali castingkusho ukubunjwa okwenziwe ngensimbi engagqwali eyi-duplex. I-Duplex Stainless Steel (DSS) isho insimbi engagqwali ene-ferrite ne-austenite i-accounting ngayinye cishe ngama-50%. Ngokuvamile, okuqukethwe kwezigaba ezincane kudinga okungenani kube ngu-30%. Endabeni yokuqukethwe okuphansi kwe-C, okuqukethwe kwe-Cr kungu-18% kuya ku-28%, futhi okuqukethwe kwe-Ni kungu-3% kuya ku-10%. Ezinye izinsimbi ezingenasici eziyi-duplex nazo ziqukethe izakhi ze-alloying ezifana ne-Mo, Cu, Nb, Ti, kanye no-N.
I-DSS inezici zensimbi engagqwali ye-austenitic ne-ferritic. Uma iqhathaniswa ne-ferrite, ine-plasticity ephakeme kanye ne-ductility, ayinakho ukushisa kwegumbi, futhi ithuthukise ngokuphawulekayo ukumelana nokugqwala kwe-intergranular nokusebenza kokushisela, kuyilapho igcina i-brittleness, i-thermal conductivity ephezulu, kanye ne-superplasticity njengensimbi engagqwali ye-ferrite. Uma kuqhathaniswa nensimbi engagqwali ye-austenitic, i-DSS inamandla aphezulu futhi ithuthukise kakhulu ukumelana nokugqwala kwe-intergranular kanye nokugqwala kokucindezeleka kwe-chloride. Insimbi engagqwali e-Duplex inokumelana nokugqwala okuhle kakhulu kwe-pitting futhi iyinsimbi engagqwali eyonga i-nickel.
Ekukhiqizeni ukulingisa, ukubunjwa okuningi kwensimbi engagqwali kuqedwa nguukutshala imali. Ingaphezulu lokulingisa kwensimbi engagqwali okukhiqizwa ukufakwa kwe-investimenti lishelela futhi ukunemba kobukhulu kulula ukulawula. Yiqiniso, izindleko zeutshalomali casting izingxenye zensimbi engagqwaliiphakeme uma iqhathaniswa nezinye izinqubo nezinto zokwakha.
