"Stainless steel" tsis yog tsuas yog xa mus rau ib hom stainless hlau, tab sis kuj muaj ntau pua hom stainless hlau.Nws yuav nyuaj me ntsis thaum koj xaiv cov hlau tsis zoo rau koj cov khoom siv.Yog li, Yuav ua li cas siv cov hlau tsis zoo tshaj plaws raws li koj xav tau?

1.Classified los ntawm txheej txheem kub

Txawm hais tias feem ntau cov hlau tsis muaj hlau muaj qhov sib txawv dua, ntau hom stainless hlau sib txawv.Xws li lub melting point ntawm 316 stainless hlau yog hais txog 1375 ~ 1450 ℃.Yog li, cais los ntawm qhov siab tshaj plaws siv qhov kub thiab txias.

2. Kev saib xyuas corrosion kuj

Nws cov corrosion kuj yog ib qho ntawm cov laj thawj rau ntau cov khoom tsim xws li stainless hlau ntau dua li cov hlau.Txawm li cas los xij, tsis yog txhua yam ntawm cov hlau tsis muaj steel sib npaug sib npaug rau corrosion, qee hom stainless hlau tuaj yeem tiv taus qee yam acidic compounds zoo dua.Austenitic stainless hlau xws li 304 lossis 316 stainless hlau nyhav kom muaj kev tiv thaiv corrosion zoo dua li lwm hom stainless hlau.Qhov no yog vim austenitic stainless hlau muaj cov ntsiab lus chromium ntau dua, uas pab txhim kho corrosion kuj (txawm hais tias nws tsis lav tsis kam rau txhua yam corrosion).

3.Hais txog ib puag ncig daim ntawv thov rau hauv kev txiav txim siab

Xyuas kom lub siab ntawm daim ntawv thov khoom uas yuav tsum tau dais.Peb yuav tsum xav txog nws lub zog tensile thaum xaiv cov khoom siv stainless hlau.Lub zog tensile yog tus nqi tseem ceeb rau kev hloov pauv ntawm cov hlau los ntawm cov yas deformation rau hauv zos concentrated yas deformation.Tom qab tus nqi tseem ceeb tshaj, cov hlau pib ntsws, uas yog, concentrated deformation tshwm sim.Feem ntau cov hlau tsis muaj steel muaj zog tensile heev.316L muaj lub zog tensile ntawm 485 Mpa thiab 304 muaj lub zog tensile ntawm 520 Mpa.

Noj tag nrho cov ntsiab lus saum toj no rau hauv kev txiav txim siab, xaiv cov khoom siv stainless hlau zoo tshaj plaws.Nws yuav muab kev ua tau zoo tshaj plaws rau koj cov kev daws teeb meem tsim khoom.Yog tias koj tsis muaj lub tswv yim thaum xaiv cov khoom siv stainless hlau.Peb yuav muab cov kev pabcuam thev naus laus zis thev naus laus zis rau koj.
