Corrosion resistant steel yog ib qho tshwj xeeb alloy steel uas muaj kev tiv thaiv zoo heev los ntawm kev ntxiv corrosion-resistant alloy tsim cov ntsiab lus xws li tooj liab, npib tsib xee, thiab chromium.

Cov hlau no tuaj yeem tiv taus yaig nyob rau hauv ntau yam corrosive media.

Nws cov corrosion kuj yog 2-8 npaug ntau dua li cov pa roj carbon zoo tib yam. Raws li lub sijhawm siv nce, qhov kev tiv thaiv corrosion ua kom pom tseeb.

Corrosion resistant steel yog ib hom hlau uas tiv thaiv corrosion, ua rau nws tseem ceeb rustproof.

corrosion resistant hlau

Stainless hlauyog cov hlau-raws li alloys uas muaj qhov tsawg kawg nkaus ntawm 10.5% chromium, uas yog txaus los tiv thaiv xeb nyob rau hauv tej yam kev mob ntawm chav tsev kub atmospheric tej yam kev mob.

Ntxiv rau qhov zoo corrosion kuj, corrosion resistant steel kuj muaj cov khoom zoo heev, vuam zog, thiab lwm yam.

Yog li ntawd, nws yog dav siv nyob rau hauv petrochemical kev lag luam, marine engineering, tshuaj lom neeg kev lag luam, ib puag ncig tiv thaiv engineering, hluav taws xob engineering thiab lwm yam kev lag luam los tsim ntau yam khoom, pipelines, cia tso tsheb hlau luam, Cheebtsam, thiab lwm yam. cov khoom siv.

Thaum Lub Peb Hlis 11, 2024, European Commission tau tshaj tawm tsab ntawv tshaj tawm hais tias nws tau ua thawj zaug los tiv thaiv cov khoom pov tseg hnub poob rov qab txiav txim zaum kawg ntawm Corrosion Resistant Steels los ntawm Tuam Tshoj, txiav txim siab tias yog tias cov kev ntsuas tiv thaiv pov tseg raug tshem tawm, kev pov tseg ntawm cov khoom. kev koom tes thiab kev puas tsuaj rau cov khoom pov tseg los ntawm EU kev lag luam yuav txuas ntxiv lossis tshwm sim dua, yog li nws tau txiav txim siab txuas ntxiv los tuav txoj haujlwm tiv thaiv kev pov tseg ntawm Suav cov khoom lag luam koom nrog.

Cov nqi se tiv thaiv kev lag luam yog 17.2% rau 27.9%.

Lub sijhawm tshawb nrhiav pov tseg hauv qhov no yog txij Lub Ib Hlis 1, 2022 txog Lub Kaum Ob Hlis 31, 2022, thiab lub sijhawm tshawb nrhiav kev puas tsuaj yog txij lub Ib Hlis 1, 2019 txog rau thaum xaus ntawm lub sijhawm tshawb nrhiav pov tseg.

Thaum Lub Kaum Ob Hlis 9, 2016, European Commission tau tshaj tawm qhov kev tshawb xyuas los tiv thaiv cov khoom pov tseg rau hauv corrosion resistant steel los ntawm Tuam Tshoj.

Thaum Lub Ob Hlis 8, 2018, European Commission tau ua qhov kev lees paub zaum kawg los tiv thaiv kev pov tseg ntawm kev tiv thaiv xeb hlau los ntawm Tuam Tshoj.

Thaum Lub Ob Hlis 8, 2023, European Commission tau tshaj tawm thawj zaug kev tshuaj xyuas lub hnub poob los tiv thaiv kev tiv thaiv corrosion hauv Suav teb.

Muaj ntau yam qauv ntawm corrosion resistant steel, uas yog tsim los ntawm ntau yam kev thov ib puag ncig thiab corrosion kuj yuav tsum tau.

Nov yog qee cov qauv zoo corrosion resistant steel:

304s ibtainless steel phaj:Cov qauv no muaj kev tiv thaiv corrosion zoo thiab kev ua haujlwm zoo, thiab siv dav hauv cov khoom noj, tshuaj, tshuaj thiab lwm yam lag luam.

316 stainless hlau phaj:Mo lub ntsiab yog ntxiv rau lub hauv paus ntawm 304 los txhim kho corrosion kuj thiab kub ua haujlwm, thiab yog haum rau corrosive ib puag ncig nrog kub thiab siab.

06Cr19Ni10:Qhov no yog austenitic stainless hlau phaj uas nws lub ntsiab Cheebtsam yog Cr, Ni, C, thiab lwm yam. Nws muaj zoo corrosion kuj thiab kev ua tau zoo thiab yog dav siv nyob rau hauv chemical kev lag luam, roj av thiab lwm yam teb.

022Cr17Ni12Mo2:Qhov no yog super corrosion-resistant stainless hlau phaj muaj li ntawm Cr, Ni, Mo, thiab lwm yam. Nws muaj cov cua kub zoo heev thiab yog dav siv nyob rau hauv petrochemical, organic tshuaj, aviation, aerospace thiab lwm yam teb.

00Cr17Ni14Mo2:Qhov no yog lub siab muaj zog stainless hlau phaj tsim los ntawm Cr, Ni, Mo, thiab lwm yam. Nws muaj kev tiv thaiv corrosion zoo heev thiab hnav tsis kam thiab feem ntau siv rau hauv cov khoom siv hauv kev lag luam tshuaj, roj av thiab lwm yam.
