Cov lus teb yooj yim yog 304 muaj 18% chromium thiab 8% npib tsib xee thaum 316 muaj 16% chromium, 10% nickel thiab 2% molybdenum. Cov molybdenum ntxiv los pab tiv thaiv corrosion rau chlorides (xws li dej hiav txwv thiab de-icing ntsev).
Koj puas paub tias koj tau txais 316 stainless hlau hloov 304 stainless hlau?
Koj tsis tuaj yeem qhia tsuas yog saib nws. Tsis pom qhov sib txawv ntawm ob daim ntawv hlau zoo ib yam, polished lossis grained tib txoj kev. Yog vim li cas koj thiaj li xav tau daim ntawv qhia txog cov khoom siv (MTR) ntawm cov khoom siv tiag tiag kom paub tseeb tias nws yog 304 lossis 316. Peb paub tseeb tias peb tau txais ib qho nrog txhua qhov khoom xa tuaj peb tau txais ntawm Nema Enclosures kom peb tuaj yeem paub tseeb peb cov neeg siv khoom tias lub thawv thiab nws cov khoom yog tsim los ntawm cov khoom siv stainless hlau, raws li tau teev tseg thiab xaj. Qee qhov me me xws li clamps thiab mounting taw, tsim los ntawm 316 stainless hlau yog cim tshwj xeeb, nyob rau hauv rooj plaub no tus naj npawb 6 nyob rau hauv ib lub voj voog, raws li qhia hauv daim duab saum toj no.
Hom 304 stainless hlau yog dab tsi thiab nws siv rau dab tsi?
Hom 304, nrog nws cov ntsiab lus chromium-nickel thiab cov pa roj carbon tsawg, yog cov khoom siv tau zoo tshaj plaws thiab siv dav ntawm austenitic stainless hlau. Nws cov alloys yog tag nrho cov kev hloov kho ntawm 18% chromium, 8% nickel austenitic alloy. Hom 304 ua pov thawj kom tiv taus oxidation, corrosion, thiab kav ntev. Txhua yam muab kev yooj yim ntawm fabrication thiab tu, tiv thaiv cov khoom sib kis muaj ntau yam ua tiav thiab tshwm sim. Hom 304 stainless hlau yog siv nyob rau hauv corrosion resistant hluav taws xob enclosures, pib molding thiab trim, log npog, cov khoom siv hauv chav ua noj, hose clamps, tso manifolds, stainless hardware, cia tso tsheb hlau luam, siab hlab ntsha thiab piping.
