1.Definition thiab cov yam ntxwv ntawm stainless hlau hloov hlau
Stainless hlau hloov pauv hais txog cov ntaub ntawv ntev nrog cov khaub ncaws hnav zoo nkauj cross, feem ntau hais txog plaub meters ntev thiab sib faib ua kev du puag ncig thiab bar dub. Cov du puag saum npoo yog du thiab yog ua tiav los ntawm Qisi-dov; Cov npoo dub yog xim dub thiab ntxhib thiab yog ncaj qha kub-dov.
Stainless hlau hloov Bar muaj ntau yam khoom zoo heev. Ua ntej, nws oxidation tiv taus yog qhov zoo tshaj plaws. Piv txwv li, 310s Stainless Hlau Round bar muaj ntau dua zoo dua creep lub zog vim yog cov neeg chromium thiab npib siab dua, tuaj yeem txuas ntxiv ua haujlwm ntawm cov kub, thiab muaj qhov kub siab. Thib ob, nws muaj muaj zog corrosion tsis kam. Piv txwv li, 316L stainless hlau hloov bar tau zoo heev corrosion tsis kam, vim qhov kev sib ntxiv ntawm mo, thiab cov khoom ntawm cov khoom txias txias-rolled muaj cov ntsej muag zoo; Tom qab ntxiv mo rau 316 stainless hlau puag ncig bar, corrospheric corrosion thiab siab kub yog qhov tshwj xeeb, thiab nws tuaj yeem siv nyob rau hauv cov xwm txheej hnyav. Ntxiv rau, stainless hlau puag bar muaj cov khoom siv zoo, xws li muaj kev kub siab thiab cov tshuab hluav taws xob, thiab yog corrosion-resistant nyob rau hauv cov huab cua. Nyob rau tib lub sijhawm, stainless hlau puag bar muaj cov khoom huv zoo thiab yog siv dav hauv kev lag luam kev lag luam thiab kev phais cov khoom noj. Tsis tas li ntawd, stainless hlau hloov cov khoom tseem muaj kev zoo nkauj, nrog txoj kev zoo nkauj du. Lawv tuaj yeem ua tiav rau hauv cov chaw muaj zog, txhuam cov chaw, cov duab ci ci thiab tuaj yeem ua tiav dua raws li cov kev xav tau sib txawv.
2. Siv cov hlau Stainless Hloov Hlau
2.1 Ntau thaj teb
Stainless hlau hloov cov tuav muaj qhov kev thov dav dav thiab ua lub luag haujlwm tseem ceeb hauv ntau thaj teb. Nyob rau hauv lub tshav pob ntawm nkoj Hauv kev lag luam petrochemical, stainless hlau puag ncig tuaj yeem tiv thaiv cov kev tsim kho thiab cov raj mis cov khoom noj, ntim khoom noj khoom haus, ntim khoom, thiab cov raj xa khoom Vim yog lawv txoj kev nyiam huv thiab kho kom xeb. Tus kho mob teb kuj muaj cov kev xav tau siab heev rau kev nyiam huv. Kev phais thiab cov khoom siv kho mob ua cov qauv kev nyiam nyiam tu nruj.
Nyob rau hauv cov nqe lus ntawm lub tsev kho kom zoo nkauj, stainless hlau puag ncig yog siv los ua cov qauv zoo nkauj, qhov rooj thiab cov khoom zoo nkauj tsis kam tuaj yeem ntxiv kev nkag siab ntawm cov khoom kim heev thiab niaj hnub no rau lub tsev. Ib qho ntxiv, hauv thaj chaw ntawm cov khoom kho vajtse chav ua tiav, chav ua haujlwm ua los ntawm cov hlau stainless hlau puag ncig yog ruaj thiab zoo nkauj. Nyob rau hauv cov nqe lus ntawm cov cuab yeej siv khoom noj, xws li dej hiav txwv uas siv, tshuaj lom neeg, cov khoom noj, cov khoom siv roj av thiab lwm yam khoom siv lossis siv dav. Nws corrosion tsis kam tuaj yeem ua kom lub sijhawm ntev thiab ruaj khov ntawm cov khoom siv hauv cov chaw hnyav.
Cov ntaub ntawv kev faib tawm ntawm Stainless Hlau Hloov Hlau
Taw qhia rau cov ntaub ntawv nquag

2202 Stainless Hlau Round Bar: Nws yog chromium-npib tsib xee-manganese antenitic stainless hlau nrog kev ua tau zoo dua 201 ntxhais stainless.
2.2 Daim ntawv thov sib txawv ntawm cov khoom sib txawv
Nyob rau hauv cov roj kev lag luam, 316L thiab 316 Stainless hlau puag cov khoom siv hauv kev tsim kho cov nplaim hluav taws xob thiab cov raj xa khoom vim lawv cov khoom lag luam zoo tsis kam thiab kub siab. Hauv kev lag luam hluav taws xob, 304 thiab 304L stainless hlau hluav taws xob feem ntawm cov khoom siv hluav taws xob vim lawv qhov kev ua tau zoo thiab corrosion tsis kam. Hauv kev lag luam tshuaj, stainless hlau round bars ntawm ntau cov ntaub ntawv siv, thiab cov khoom siv tsim nyog raug xaiv raws li cov tshuaj sib txawv thiab ua haujlwm ib puag ncig. Piv txwv li, rau cov tshuaj corrosive heev, 316L thiab 316 Cov kab hlau tshiab hauv nruab nrab yog qhov ntau dua; Thaum lub sij hawm rau kev siv cov khoom siv ntau lawm, 304 stainless hlau puag ncig tuaj yeem ua tau raws li cov cai.
Hauv kev lag luam kws tshuaj, kev nyiam huv yog qhov tseem ceeb heev. 316L thiab 304L stainless hlau hloov cov khoom siv tau siv los ua cov twj siv phais, khoom siv kho mob, thiab lwm yam zoo ua tsis taus thiab kev ua tau zoo. Nyob rau hauv kev lag luam khoom noj khoom haus, 304 thiab 316 Cov khoom siv tsis muaj zog siv tau thiab kev ua haujlwm corrosion ntawm cov txheej txheem kev ua khoom noj.
Hauv kev lag luam machinery, stainless hlau puag cov kab ntawm cov khoom sib txawv yog xaiv raws li cov kev xav tau ntawm cov khoom siv tshuab. Piv txwv li, rau ntu uas yuav tsum muaj lub zog siab thiab coj kev tiv thaiv siab, koj tuaj yeem xaiv 420 stainless hlau round bars; Rau qhov uas xav tau kev ua haujlwm zoo, koj tuaj yeem xaiv 303 lub taub hau hlau stainless hlau.
Hauv kev tsim kho kev tsim kho, 304 thiab 316 Lub pob zeb hlau hluav taws xob ntau zaus tau siv rau cov chaw ua kom zoo nkauj thiab cov txheej txheem txheej txheem. Lawv corrosion tsis kam thiab loog tuaj yeem ntxiv tus nqi rau lub tsev. Hauv qee qhov chaw ua haujlwm tshwj xeeb, xws li cov dej hiav txwv tshwj xeeb lossis cov corrosine-muaj ntawm 316L stainless hlau hloov cov tuav yog qhov tseem ceeb.
