Stainless hlau

Txhais ntawm stainless hlau

Nyob rau hauv cov huab cua lossis tshuaj corrosion nruab nrab tuaj yeem tiv taus corrosion ntawm cov hlau alloy siab, stainless hlau yog qhov zoo nkauj thiab zoo corrosion tsis kam, tsis tas yuav tsum tau plated thiab lwm yam kev kho deg, thiab ua si lub hauv paus nto ntawm stainless hlau, siv hauv ntau yam ntawm ib hom hlau, feem ntau hu ua stainless hlau.Sawv cev ntawm kev ua tau zoo ntawm 13 chromium hlau, 18- chromium - npib tsib xee hlau thiab lwm yam hlau alloy siab.
Los ntawm metallographic taw tes ntawm view, vim hais tias stainless hlau muaj chromium thiab nto ntawm tsim ntawm ib tug heev nyias chromium zaj duab xis, cov zaj duab xis sib cais los ntawm cov pa oxygen nyob rau hauv cov hlau ntxeem tau ntawm corrosion kuj.Yuav kom tswj tau qhov corrosion kuj muaj nyob rau hauv stainless hlau, hlau yuav tsum muaj ntau tshaj 12% chromium.

Kev txhim kho keeb kwm ntawm stainless hlau

Qhov laj thawj yog vim li cas cov ntaub ntawv hlau thiab hlau tau siv dav heev yog vim muaj cov ntsiab lus ntawm cov hlau ore deposits, loj cia, kuj economic mining thiab smelting, thiab muaj zog txias thiab kub deformation muaj peev xwm ntawm semi-tiav hlau thiab hlau.Cov khoom tiav lawm muaj cov khoom siv zoo heev (lub zog, plasticity thiab cuam tshuam tsis kam) thiab cov khoom siv ua haujlwm (txiav, vuam, txias deformation, thiab lwm yam).Tab sis piv nrog cov ntaub ntawv silicic acid, cov khoom siv hluavtaws polymer thiab qee cov hlau tsis muaj hlau, nws qhov tsis zoo tshaj plaws yog: nyob rau hauv huab cua lossis acid, alkali, ntsev thiab lwm yam kev tshaj tawm, yooj yim poob phaus vim corrosion, thiab txawm tias tag nrho kev puas tsuaj.

Hom stainless hlau

Stainless hlau tuaj yeem raug cais los ntawm kev siv, tshuaj muaj pes tsawg leeg thiab metallographic qauv.
Cov hlau austenitic yog tsim los ntawm 18% chromium -8% npib tsib xee, thiab tus nqi ntawm txhua lub caij sib txawv, thiaj li tsim ntau hom hlau.
Kev faib tawm los ntawm cov tshuaj muaj pes tsawg leeg: ①Cr series: ferrite series, Martensite system series ②Cr-Ni series: Austenite system series, txawv txav series, nag lossis daus hardening series.
Kev faib tawm ntawm cov qauv metallographic: (1) austenitic stainless hlau, (2) ferritic stainless hlau, (3) martensitic stainless hlau, (4) duplex stainless hlau, (5) nag lossis daus hardening stainless hlau
