Tso lus
Hauv kev lag luam thiab cov txheej txheem piping systems, stainless hlau yeeb nkab tseem yog cov khoom ntawm kev xaiv vim nws qhov zoo xws li corrosion resistance, mechanical zog, thiab kev pab lub neej ntev. Gnee tuav cov khoom lag luam loj ntawm 304, 316, thiab 409 stainless hlau kav hauv ob qho tib si seamless thiab welded cov ntaub ntawv, ua raws li ASTM A312 / A213 / A268 cov qauv, kom ntseeg tau ceev ceev thiab kev ruaj ntseg zoo rau txhua qhov kev lag luam loj.
Dab tsi yog qhov txawv ntawm 304, 316, thiab 409 stainless hlau kav?
304 yog qhov feem ntau siv rau kev lag luam, 316 muaj kev tiv thaiv corrosion zoo dua (tshwj xeeb tshaj yog tiv thaiv cov tshuaj chlorides), thaum 409 yog kev lag luam ntau dua rau siab - kub thiab kev siv tsheb siv hluav taws xob.
