Stainless hlau thiab hlau nplaum

Ntau tus neeg muas zaub mus rau tom khw mus yuav cov hlau tsis muaj steel, thiab lawv nqa cov hlau nplaum me me nrog lawv. Yog tsis muaj hlau nplaum, nws yuav tsis xeb. Qhov tseeb, qhov no yog kev nkag siab yuam kev. Txawm hais tias stainless hlau sawb tsis muaj hlau nplaum yog txiav txim los ntawm nws cov qauv. Thaum lub sij hawm solidification txheej txheem ntawm molten steel, vim qhov sib txawv solidification kub, stainless hlau nrog txawv qauv xws li "ferrite", "austenite" thiab "martensite" yuav tsim. Ferritic" thiab "martensitic" stainless hlau yog tag nrho cov hlau nplaum. "Austenitic" stainless hlau muaj cov khoom siv kho tshuab zoo thiab cov txheej txheem kev ua tau zoo thiab weldability, tab sis tsuas yog hais txog kev tiv thaiv corrosion, hlau nplaum "ferritic" stainless hlau muaj zog dua "austenitic" stainless hlau. Tam sim no, lub npe hu ua 200 series thiab 300 series stainless hlau uas muaj cov ntsiab lus siab manganese thiab cov ntsiab lus nickel qis hauv kev ua lag luam tsis yog hlau nplaum, tab sis lawv qhov kev ua tau zoo nyob deb ntawm 304 nrog cov ntsiab lus siab nickel, ntawm qhov tsis sib xws, 304 yog stretched thiab annealed., polishing, casting thiab lwm yam txheej txheem kuj yuav microstrip sib nqus, yog li nws yog ib qho kev nkag siab tsis zoo thiab tsis paub txog kev txiav txim siab zoo ntawm stainless hlau los ntawm kev siv stainless hlau sawb yam tsis muaj hlau nplaum.
