430 stainless hlau nto du, kub qaug zog, kua qaub, alkaline roj, tshuaj thiab lwm yam xov xwm corrosion kuj.High plasticity, toughness thiab mechanical zog;201 Stainless hlau yeeb nkab muaj cov yam ntxwv ntawm acid tsis kam, alkali tsis kam, siab ceev tsis muaj pinholes, thiab lwm yam, yog tsim los ntawm ntau yam saib, pluaj hauv qab npog thiab lwm yam khoom zoo.201 Stainless hlau kav tuaj yeem siv rau hauv cov kav dej zoo nkauj, cov kav dej, thiab qee cov khoom siv kos duab.
430 stainless hlau thiab 201 stainless hlau sib txawv
430 stainless hlau yog martensitic stainless hlau, martensitic stainless hlau thiab zoo tib yam alloy hlau muaj tib yam ntxwv ntawm hardening los ntawm quenching, martensitic chromium stainless hlau nyob rau hauv quenching - tempering tej yam kev mob, nce cov ntsiab lus ntawm chromium tuaj yeem nce cov ntsiab lus ferritic, yog li txo qhov hardness thiab tensile zog.Nyob rau hauv annealing tej yam kev mob, lub hardness ntawm tsawg carbon martensitic chromium stainless hlau nce nrog qhov nce ntawm chromium cov ntsiab lus, thaum lub elongation txo me ntsis.Nyob rau hauv cov xwm txheej ntawm qee cov ntsiab lus chromium, qhov nce ntawm cov ntsiab lus carbon yuav ua rau cov hlau tawv tom qab quenching, thiab cov yas yuav txo qis.
Tom qab qis kub quenching, cov nyhuv ntxiv ntawm molybdenum yog qhov pom tseeb heev.Lub hom phiaj tseem ceeb ntawm kev ntxiv molybdenum yog los txhim kho lub zog, hardness thiab theem nrab hardening nyhuv ntawm hlau.Hauv martensitic chromium-nickel stainless hlau, cov ntsiab lus ntawm δ ferrite hauv cov hlau tuaj yeem raug txo los ntawm qee qhov nyiaj npib tsib xee, kom cov hlau tuaj yeem tau txais qhov siab tshaj plaws hardness nqi.
210 stainless hlau yog chromium-nickel austenitic stainless hlau, austenitic stainless hlau yog tsis-sib nqus thiab muaj siab toughness thiab plasticity, tab sis lub zog yog tsawg, nws yog tsis yooj yim sua kom ntxiv dag zog los ntawm theem hloov, tsuas yog los ntawm txias ua hauj lwm kom ntxiv dag zog rau.Yog tias S, Ca, Se, Te thiab lwm yam ntxiv, nws muaj kev ua haujlwm zoo.Yog tias nws muaj Mo, Cu thiab lwm yam ntsiab lus, nws tuaj yeem tiv thaiv corrosion ntawm sulfuric acid, phosphoric acid, formic acid, acetic acid, urea thiab lwm yam.Yog tias cov pa roj carbon ntsiab lus ntawm cov hlau no tsawg dua 0.03% lossis muaj Ti, Ni, nws tuaj yeem txhim kho nws cov intergranular corrosion kuj.High silicon austenitic stainless hlau concentrated nitric acid muaj corrosion kuj zoo.Vim tias austenitic stainless hlau muaj cov khoom siv dav thiab zoo, nws tau siv dav hauv txhua qhov chaw ntawm lub neej.
Hauv cov ntsiab lus, 430 stainless hlau thiab 201 stainless hlau muaj lawv tus kheej zoo thiab cov txiaj ntsig, 430 stainless hlau acid acid kuj, alkali tsis kam, hardness tus nqi yog muaj zog, 210 stainless hlau yas yog zoo, muaj kev ua tau zoo, tuaj yeem ua tau raws li qhov xav tau, xaiv qhov tsim nyog hom stainless hlau.
