Alloy 304/304L yog tus qauv 18-8 stainless hlau (18% Chromium thiab 8% Nickel) uas yog siv rau ntau hom kev siv dav dav. Cov alloy muaj qhov zoo corrosion kuj nyob rau hauv ntau yam atmospheric tej yam kev mob raws li zoo raws li oxidizing thiab txo qhov chaw.
304/304L muaj kev sib sau zoo thiab vuam yam ntxwv. Nws kuj muaj qhov ua tau zoo heev rau intergranular corrosion nyob rau hauv raws li-welded mob. Qib dual yuav yog qhov tseem ceeb yog tias qhov ntsuas qhov hnyav tau ua tiav. Qhov no yog qhov twg intergranular corrosion los rau hauv daim duab thiab muaj cov pa roj carbon tsawg dua ua rau nws nyuaj rau Chromium Carbide los nag hauv 797 txog 1580 degF (425 txog 860 degC) ntau yam thaum lub vuam mus ntev ntev. mus rau qhov ntsuas hnyav. Thaum kawg, nws muaj lub zog zoo thiab toughness ntawm qhov kub thiab txias.

Nyob rau hauv ib puag ncig sov chloride, nws yog qhov yooj yim rau pitting thiab crevice corrosion thiab tseem muaj kev ntxhov siab corrosion cracking saum 140 degF (60 degC).
Dav dav heev. Nws yog siv tau yuav luag txhua qhov chaw - cov hlab ntsha siab, cov khoom siv hluav taws xob, cov twj thiab cov li qub, kev lag luam khoom noj thiab cawv, kev lag luam tshuaj, kev lag luam cryogenic, kev lag luam fais fab thiab lwm yam.
