Tsawg tsis paub qhov tseeb txog stainless hlau raj

Tib neeg tau siv stainless hlau tau ntev heev tam sim no, txij li xyoo 1990s. Nws yog siv nyob rau hauv ntau sectors. Kev lag luam hauv tsev feem ntau yog siv cov hlau tsis muaj hlau dav dav yog li cia peb pom dab tsi ua rau cov hlau tsis muaj hlau tsis zoo li nws tau siv ntau yam.

Qee qhov tseeb txog stainless hlau:
Qee cov hlau alloy yog rhuab thiab welded rau hauv cov duab sib txawv thiab qhov ntau thiab tsawg uas muaj txiaj ntsig zoo los hloov cov hlau stainless 202 raj los tsim qee yam khoom ntawm lub cev thiab tshuaj lom neeg. Hlau yog cov khoom siv rov ua dua tshiab. Hlau alloy yog siv nyob rau hauv ntau yam lag luam xws li slag ua, zeb nplai kev lag luam thiab ua kua. Steelmaking plua plav thiab sludge kuj tuaj yeem sau thiab siv los ua lwm yam hlau xws li zinc.

Lub zog siab thiab cov khoom siv kho tshuab siab yog cov yam ntxwv tseem ceeb ntawm cov hlau tsis muaj steel, uas ua haujlwm zoo piv rau cov pa roj carbon steel. Stainless hlau tubing yog ntau resistant rau corrosive ntsiab dua lwm yam hlau tubing vim nws chromium, npib tsib xee thiab molybdenum muaj pes tsawg leeg. Stainless hlau tubing muaj ntau yam kev siv vim nws lub zog, yooj, toughness, corrosion kuj thiab txo coefficient ntawm kev sib txhuam.

Vim nws lub neej ntev, stainless hlau tubing tsis tshua kim los tswj thiab tuaj yeem txuag koj nyiaj dhau sijhawm. Shipbuilding thiab marine daim ntawv thov ua kom zoo tshaj plaws ntawm cov khoom siv no.

Cov kev lag luam nuclear thiab aerospace kuj tseem siv cov hlau tsis muaj steel vim nws tsis kam oxidation ntawm qhov kub thiab txias. Stainless hlau nthuav dav thiab sib cog lus vim nws muaj zog dua lwm yam hlau.

Yog tsis poob toughness, stainless hlau tuaj yeem kos rau hauv cov xov hlau nyias vim tias nws muaj qhov tsis zoo. Ntau lub tuam txhab stainless hlau muab cov hlau tsis muaj hlau mesh uas zoo thiab malleable txaus hnav. Vim tias cov khaub ncaws stainless hlau tiv taus cua sov thiab hluav taws xob, nws feem ntau siv hauv kev lag luam hluav taws xob thiab textile.

Qee cov hlau tsis muaj hlau yog hlau nplaum thiab koj yuav tsum paub txog qhov no. Stainless hlau tau muab faib ua pawg, txhua qhov sib txawv ntawm cov alloy muaj pes tsawg leeg thiab atomic kev npaj, uas ua rau cov khoom sib nqus sib txawv. Feem ntau, ferritic qib yog sib nqus, tab sis qib austenitic tsis yog.

Ib qho yooj yim ntawm stainless hlau zoo li lub bar ntawm xab npum yog tsim los ntawm stainless hlau. Stainless hlau xab npum tsis tua kab mob los yog lwm yam kab mob nyob rau hauv tib txoj kev raws li zoo tib yam xab npum, tab sis nws muaj peev xwm pab tau neutralize unpleasant tsw ntawm tes. Tom qab tuav qej, dos los yog ntses, tsuas yog rub lub bar ntawm koj txhais tes. Cov ntxhiab tsw yuav tsum ploj mus.
