    Ibisobanuro

    Alloy 20 ni nikel-fer-chromium ishingiye, austenitis alloy ifite imbaraga zo kurwanya ruswa mu bidukikije birimo aside sulfurike nibindi bitangazamakuru byinshi bikaze. Iyi mavuta ihujwe na niobium kugirango irwanye ruswa. Alloy 20 irashobora gutanga ikiguzi gishobora kuzigama mugihe witonze ugereranije na nikel yo hejuru ishingiye kumavuta, mugihe ikora ibyuma bisanzwe bitagira umwanda.

     

    Inganda na Porogaramu

    Alloy 20 ikoreshwa mu nganda zinyuranye, zirimo gutunganya imiti, peteroli no gutunganya, inyanja, imiti no gutunganya ibiryo. Porogaramu yo gukoresha amaherezo irimo ibigega byo kubika, kuvanga ibigega, abigaragambyaga, pompe na valve ibice, ibikoresho byo gutunganya ibiryo, ibifunga hamwe nibikoresho. Porogaramu igarukira ku bushyuhe ntarengwa bwa 1000 ° F kuri ASME. Ni ngombwa kandi kumenya niba ibikenewe byo kurwanya ruswa bishobora kugerwaho mubidukikije byatanzwe.

    Kurwanya Ruswa

    Alloy 20 ifite imbaraga zo kurwanya aside sulfurike. Uyu musemburo urerekana kandi imbaraga zikwiye muri aside ya fosifori, aside nitricike hamwe n ibisubizo byumunyu wamazi. Alloy 20 nuburyo bwiza cyane iyo chloride ihangayikishije ruswa yamenetse nikibazo, kuko irwanya gutobora no kwangirika. Hagomba kwitonderwa muri ion ya chloride irimo ibidukikije kuko igipimo cya ruswa gishobora kwiyongera cyane.

    Guhimba no kuvura ubushyuhe

    Alloy 20 irashobora gushirwaho haba gushyuha-gukora cyangwa gukonja-akazi ukoresheje uburyo gakondo. Ibikoresho bishyushye bigomba gushyuha hagati ya 2100 ° F na 2250 ° F hamwe no kugenzura ubushyuhe bwitondewe kugirango ibikoresho bitagwa munsi ya 1800 ° F mbere yo guhimba. Nyuma yo gukora bishyushye, shyiramo ibikoresho ushushe kuri 1725 ° F na 1850 ° F byibuze byibuze iminota 30 kuri santimetero yubugari ukurikirwa no kuzimya amazi.

    Iyo hagabanijwe kugabanya ibibazo, shyushya ubushyuhe buri munsi ya 1000 ° F hakurikiraho kuzimya amazi nyuma yigihe cyifuzwa mubushyuhe. Annealing Alloy 20 igomba kuba hagati ya 1725 ° F na 1850 ° F muminota 30 mubushyuhe kuri santimetero y'ubugari. Ubukomezi buke burashobora kuboneka ushushe gushika kuri 2100 ° F ariko ibye birashobora kugira ingaruka mbi kumyuka yumuti.

    Welding Alloy 20 isanzwe ikorwa binyuze, TIG, MIG kimwe no gusudira arc gusudira (SAW) ukoresheje icyuma cyuzuza, ER320LR kuri TIG na MIG na E320LR kuri SAW. Iyo gusudira kubintu bidasa nka 316 cyangwa birenga nka C276 naAmavuta 22, AWS ERNiCrMo-3 irashobora gukoreshwa kuri TIG na MIG mugihe ukoresha ENiCrMo-3 kuri SAW.
