Nyob rau hauv lub realm ntawm metallurgy, kev faib tawm ntawm alloys feem ntau ua rau muaj cov lus nug sib txawv ntawm ob qho no "thiab cov ntawv thov kom teb tau cov lus nug no
Txhais cov tswv yim
Stainless hlau yog lub tswv yim ntawm cov qauv hlau muaj qhov tsawg kawg nkaus ntawm cov qauv oxium, nws tsis yog cov qauv sib xws Pawg raws li micrubtructure: Austenitic, Ferritic, martensitic, duplex, thiab nag lossis daus-tawv.
Nickel-based alloys, los ntawm kev sib piv, yog txhais tau tias muaj cov khoom siv kub ua ke xws li cov khoom siv hluav taws xob zoo xws li cov khoom siv hluav taws xob ntau yam xws li inconel ® thiab Hastelloy® Alloys, uas muaj {{4 {}}}% nickel .
Lub luag haujlwm ntawm Nickel hauv Stainless Hlau
Nickel ua si lub luag haujlwm tseem ceeb hauv kev tshwj xeeb ntawm cov qauv stainless hlau me me, tshwj xeeb tshaj yog Austenitic hom zoo li 304 thiab 316:
- 304 Stainless Hlau:Muaj 8-10.5% npib tsib xee, uas ua rau muaj teeb meem thiab ve}}} Kev ua vajtse .
- 316 Stainless Hlau:Suav nrog 10-14% npib tsib xee nrog rau chloride corrosion. Cov khoom siv roj av thiab cov khoom siv kho mob {3}
Txawm li cas los xij, txawm tias nyob hauv cov kab mob siab no, hlau nyob ib qho tseem ceeb (kwv yees}%), paub qhov sib txawv ntawm cov nickel-based alloys.
Qhov sib txawv tseem ceeb hauv cov khoom thiab cov ntawv thov

Corrosion Kuj: Stainless hlau tso siab rau ntawm chromium oxide rau kev tiv thaiv, thaum cov neeg npib tsib xee ua rau cov kua qaub thiab kub-{2}}
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Cov npib Nickel-Raws Li Cov Khoom Kub Tshaj Plaws Lub Zog Kub, ua rau lawv tsis tseem ceeb hauv cov roj av thiab cov tshuaj tua hluav taws xob.
Tus nqi: Stainless hlau feem ntau muaj nyiaj ntau dua, nrog cov npe npib tsib xee, nrog rau lawv cov ntsiab lus Nickel ntau dua .

Xaus Lus: Piav qhia meej rau kev faib tawm
Stainless hlau tsis yog npib tsib xee-based alloy. nws cov qib sib xyaw ua ke hauv qee qib kev faib tawm hauv cov qib {}}
Nkag siab txog qhov txawv no yog qhov tseem ceeb rau cov khoom siv uas muaj kev tawm tsam ntawm cov tub ntxhais kawm qib siab, tab sis lawv cov tsev neeg txuas ntxiv mus hloov dua tshiab, tab sis lawv cov tsev neeg txuas ntxiv mus hloov dua tshiab,
Nyob rau hauv cov lus ntawm lub koom haum thoob ntiaj teb ntawm vuam muag: "Cov khoom siv tsis zoo rau kev txiav txim siab Nickel nrog kev txiav txim siab cov khoom lag luam engineering.
