430 stainless hlau nto du, rhaub zog, acid, alkaline roj, tov thiab lwm yam xov xwm tiv thaiv corrosion. Siab plasticity, kev nruj thiab tshuab zog; 201 Cov yeeb nkab steel hlau muaj cov yam ntxwv ntawm acid tsis kam, alkali tsis muaj ntau yam uas tsis muaj pinholes, lub pluaj hauv qab npog thiab lwm cov khoom siv hauv qab. 201 stainless hlau kav tuaj yeem siv rau hauv cov kav dej zoo nkauj, cov kav dej muaj zog, thiab qee cov khoom lag luam ntiav.
430 stainless hlau thiab 201 stainless hlau txawv
430 stainless hlau yog martitic stainless hlau, martensitic steel hlau muaj cov ntsiab lus zoo ib yam, nce cov ntsiab lus ferritic, yog li txo lub hardness thiab tensile lub zog. Nyob rau hauv annealing tej yam kev mob, lub hardness ntawm cov pa roj carbon martensitic chromium stainless hlau nce nrog nce ntawm chromium cov ntsiab lus, thaum lub elongation txo me ntsis. Raws li cov xwm txheej ntawm ib qho ntsiab lus chromium ib co yuav ua rau muaj cov pa roj carromium yuav ua kom muaj zog ntawm cov hlau tom qab quenching, thiab cov yas yuav poob.
Tom qab tsawg kub quenching, qhov ntxiv ntawm molybdenum yog pom tseeb heev. Lub hom phiaj tseem ceeb ntawm kev ntxiv molybdenum yog los txhim kho lub zog, hardness thiab theem nrab kev ua kom haum ntawm cov hlau. Nyob rau hauv Martensitic chromium-npib stainless hlau, cov ntsiab lus ntawm Δ ferrite nyob rau hauv cov hlau tuaj yeem txo los ntawm ib tug nqi ntawm ob npib, yog li ntawd cov hlau tuaj yeem tau txais qhov siab tshaj plaws tus nqi.
210 Stainless hlau yog chromium-npib tsib xee ustenitic stainless hlau tsis muaj zog thiab muaj zog, tab sis lub zog tsis muaj zog, tsuas yog los ntawm kev ua haujlwm txias kom ntxiv dag zog. Yog tias S, CA, SE, Te thiab Te lwm cov ntsiab lus ntxiv, nws muaj zoo machinity. Yog tias nws muaj MO, CU thiab lwm yam ntsiab lus, nws tseem tuaj yeem tiv thaiv kev xeb ntawm sulfuric acid, formic acid, acid acid, acetic acid, urea thiab lwm yam. Yog tias cov ntsiab lus carbon ntawm xws li cov hlau yog tsawg dua 0.03% lossis muaj ti, ni, nws tuaj yeem txhim kho nws txoj kev txhim kho hauv kev txhim kho. Siab silicon Austenitic stainless hlau paub nitric acid muaj zoo corrosion tsis kam. Vim tias Austenitic stainless hlau muaj kev ua haujlwm zoo 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 thiab cov txiaj ntsig stainless hlau yog qhov zoo, tuaj yeem raws li cov kev xav tau, xaiv cov qauv tsim nyog ntawm cov hlau uas tsim nyog.
