Qhov twg yog ib qho zoo dua hauv kev ua xeb, 1.4301 lossis 1.4372 stainless hlau?
1.4301 lub siab nickel-chromium (CR17.5-19.5%, NI8-10.5%), thiab yog tsim nyog rau cov dej hiav txwv thiab cov dej hiav txwv.
Kev kub siab oxidation: 1.4301 tuaj yeem siv rau lub sijhawm ntev tsawg dua lossis sib npaug nrog 800 degree, thiab 1.4372 tsuas yog tsim nyog rau tsawg dua lossis sib npaug nrog 600 degree.
Nqe rau ib kilogram ntawm 1.4301 stainless hlau?
1.4372: Vim nws cov ntsiab lus npib tsib txhiab xyoo qis (txog 50% ntawm 1.4301), tus nqi qis dua, thiab nws yog qhov kev ua kom zoo nkauj uas tsis zoo, tus nqi qis.
1.4301: Nws tau ntsuas kev ua tau zoo thiab yog "panacea" ntawm cov hlau stainless. Txawm hais tias tus nqi siab dua, nws yog tus nqi ntau dua hauv kev ua kom ib puag ncig corrosive thiab muaj ntev
Puas yog 1.4372 thiab 1.4301 stainless hlau hlau nplaum?
Ob qho tib si yog Austenitic stainless hlau thiab tsis muaj sib nqus ntawm chav tsev kub (tshwj tsis yog txias ua haujlwm martensitic kev hloov pauv, lawv yuav tsis muaj sib nqus tsis muaj zog).
