Vim li cas siv 904L chev rau cov kev siv kub-resistant?

Thaum xaiv cov ntaub ntawv stainless hlau stainless rauCov Kev Siv Thaum Tshav Kub Kub-resistant, engineers thiab cov tub ceev xwm ua haujlwm feem ntau saib dhau cov qauv qib zoo li 304 thiab 316. Ib cov khoom siv siab uas sawv yog904L Stainless Hlau, tshwj xeeb hauvChev Daim NtawvCov. Nrog rau kev tiv thaiv zoo heev rau cua sov, xeb, thiab oxidation,904L Stainless Hlau Chevyog qhov kev xaiv zoo tshaj plaws hauv kev xav tau kev lag luam xws li kev ua tshuaj lom neeg, tiam neeg siv zog, thiab marine engineering.

Hauv tsab xov xwm no, peb yuav tshawbVim li cas 904l chil yog qhov zoo rau kev kub-ib puag ncig, qhov cuam tshuamCov Qauv Thoob Ntiaj Teb(Astm, en, jis), thiab nws muab piv rau lwm tus hlau tsis muaj.

Vim li cas siv 904L chev hauv tshav kub-resistant cov ntawv thov?

1. Kev Kub Siab Kub-Lub Zog

904L stainless hlau tswj cov neeg kho tshuab ruaj khov thiab microstructure kev ncaj ncees ntawmnce qhov kub kub txog ~ 450 degree (842 degree f)nyob rau hauv kev pabcuam txuas ntxiv. Nws muab cov thermal ua tau zoo dua piv rau 304 thiab 316, uas tuaj yeem raug kev txom nyem los ntawm kev nkag mus thiab lub zog tsis tau ploj mus ntev.

2. Superior oxidation tsis kam

Ua tsaug rau nwsCov ntsiab lus chromium thiab npib tsib xee, 904l tiv thaiv oxidation thiab teev hauv cov huab cua lossis oxidizing ib puag ncig. Qhov no ua rau nws zoo tagnrho rau kev hloov cua sov, cov hnab looj hnab looj, lossis cov tshuab raj hluav taws xob qhov twg pa taws.

3. Kuj mus rau thermal qaug zog

904L coils tau siv nyob rau hauv thermal cycles yam tsis muaj cracking lossis nkees tsis ua tiav, uas yog qhov tseem ceeb hauv kev siv li:

Cov Hluav Taws Xob Tshav Kub Kub

Evaporators

Khib roj

Cov Khoom Siv Desalination

4. Weldability nyob rau hauv high-kub tshuab

Coil cov ntaub ntawv feem ntau yuav tsum tau uaTxiav, puab, thiab weldedCov. 904L muajZoo heev Weldability, ua rau nws haum rau fabricating complex cov khoom siv nyob rau hauv high-kub system.
