316 ishidi lensimbi engenasiciInezici ze-Ferrite ne-Austenite, kanye namakhono amahle okumelana nengcindezi ye-chloride nokumelana nokugqwala.I-2205 iyinsimbi eyi-duplex, iqukethe u-21% Cr, 2.5%Mo kanye no-4.5% we-Ni-N.amandla ayo okugoba aphindwe kabili kune-Austnite.Ikhono lingenza abaklami behlise isisindo semikhiqizo ekuklameni.Inezinzuzo ezingaphezu kuka-317L insimbi engagqwali.
Ngoba316 ishidi lensimbi elicwebezelayo elingenasiciine-Cr ne-Mo eningi, ngakho inamandla okuvimbela umgodi.Insimbi engagqwali e-Duplex ingaqinisekisa ukuthi insimbi inamandla amakhulu okumelana nengcindezi kanye nokumelana nokugqwala namandla emishini aphezulu.
I-316 insimbi engagqwali inokuziphatha kwemishini, ukumelana nokugqwala kanye nokushisela okuhle.Isetshenziselwa imboni ye-petroleum negesi yemvelo, i-oceanerring, imboni yamakhemikhali nezinye izimboni.Njengamanje, imboni kawoyela negesi yemvelo isebenzisa amashubhu kawoyela angaphezu kuka-850km enziwe ngama-duplex stainless steels.Iningi lalezi zinsimbi eziyi-duplex amapayipi ensimbi engenamthungo angu-316L (futhi izingxenye zingamapayipi ensimbi engagqwali ayi-S31803 namapayipi angu-2507 ensimbi engenasici).Ngenxa yokuthi indawo yegesi yemvelo inokugqwala okuphezulu, amashubhu anengcindezi ephezulu wonke amapayipi angama-316 ensimbi engagqwali.
I-316 insimbi engagqwali ingasetshenziswa kulezi zici: imvelo ye-chloride engathathi hlangothi, imboni yokuhluza, imboni kawoyela, imboni yamakhemikhali, imboni ye-petroleum negesi yemvelo, imboni ye-pulp nephepha, imboni kamanyolo, imboni ye-urea, imboni kamanyolo we-phosphate, imvelo yamanzi olwandle, amandla kanye nemvelo. imboni yokuvikela, imboni elula kanye nemboni yokudla, ukudla nezinsiza zemboni yemithi.
I-316 insimbi engagqwali inokumelana nokugqwala okuhle ngoba ubuso bayo bunefilimu ye-passivation etholakala kumoya-mpilo ozinzile, ngakho-ke insimbi engagqwali engu-316 iyathandwa.
