Duplex Steel Daim Hlau & Cov Ntawv Qhia & Coils
Thaum chromium yog ib tus neeg sawv cev tseem ceeb hauv A335 P91 piping, nws yog lub siab tiv taus oxidation thaum kub. Txij li cov kav dej no yog kho saum npoo lossis coated, lawv kuj tau muaj kev tiv thaiv tiv thaiv kev xeb. Cov txheej sab tuaj yeem ua tiav los ntawm ntau cov txuj ci xws li passivation, phosphating, roj raus, varnishing thiab tua cov npawg.
Nruj me ntsis kev hais lus, txhua tus steel yog ib qho alloy, tab sis tsis yog txhua tus hlau yog hu ua "Alloy Steel". Cov hlau yooj yim tshaj plaws yog hlau (FE) suav nrog cov pa roj carbon (c) (txog 0.1% rau 1%, nyob ntawm seb puas muaj dab tsi (tshwj tsis yog cov neeg negrigible traces); Cov no yog hu ua cov hlau siv roj carbon. Txawm li cas los xij, lub sij hawm "hlau" yog tus qauv uas yog hais txog cov hlau nrog lwm cov khoom sib txuas ntxiv rau cov pa roj carbon. Ib txwm muaj willoyants suav nrog manganese (npib tsib xee), npib tsib xee, chromium, molybdenum, vanadium, silicon, thiab boron. Tsawg dua cov ubyants suav nrog txhuas, cobalt, cerium, cerium, cerium, cerium, titanium, tungsten, tin, zinc, thiab zirconium.
Cov khoom meej meej ntawm peb txoj kev xav tau ntawm A335 tau ua raws li cov kev xav tau. Peb ua tau raws li txhua qhov yuav tsum muaj rau tus qauv thiab cov qauv loj uas yog cov khoom lag luam hlau loj. Peb yog cov khoom xa tawm ib txwm ntawm Alloy Steel cov khoom lag luam nyob rau hauv ntau yam qauv, qauv, qauv thiab kev cai sib cai.
