400 series stainless hlau yog ib tsev neeg ntawm stainless hlau alloys uas nws lub ntsiab feature yog ib tug ntau dua chromium ntsiab lus. Qhov no series ntawm stainless hlau feem ntau suav nrog ntau hom qauv, feem ntau yog 410 stainless hlau thiab 430 stainless hlau. Piv nrog 200 series thiab 300 series stainless hlau, 400 series stainless hlau muaj cov yam ntxwv hauv qab no:
High hardness: 400 series stainless hlau muaj siab hardness, tshwj xeeb tshaj yog 410 stainless hlau, uas tuaj yeem tau los ntawm kev kho cua sov kom tau txais cov tawv tawv dua, ua rau nws zoo heev hauv qee daim ntawv thov uas yuav tsum muaj zog thiab hnav tsis kam.
Nruab Nrab Corrosion Resistance: 400 series stainless hlau muaj ntau dua ntawm chromium, uas muab qee qhov kev tiv thaiv corrosion. Tshwj xeeb tshaj yog 410 stainless hlau muaj zoo corrosion kuj thiab yog haum rau ib co me me corrosive ib puag ncig.
Sib nqus: Feem ntau 400 series stainless hlau yog hlau nplaum, uas ua rau lawv muaj txiaj ntsig zoo hauv qee yam kev siv.
Grindability: Vim muaj hardness siab, 400 series stainless hlau feem ntau yog siv rau hauv kev tsim cov riam thiab txhua yam khoom, xws li hniav, bearings, li qub, thiab lwm yam.
Tus nqi qis: txheeb ze rau qee cov nickel stainless hlau siab, tus nqi qis ntawm 400 series stainless hlau ua rau lawv xaiv pheej yig.
Plasticity: 400 series stainless hlau muaj qee yam ntawm cov yas, thiab tuaj yeem ua tiav nrog qee cov duab nyuaj.
400 series stainless hlau tuaj yeem muab faib ua ntau hom kev faib tawm raws li nws qhov tshwj xeeb muaj pes tsawg leeg thiab cov yam ntxwv, feem ntau yog 410 stainless hlau thiab 430 stainless hlau:
410 Stainless Steel (UNS S41000): 410 Stainless Hlau yog lub hom phiaj dav dav uas tsis tshua muaj carbon stainless hlau uas muaj txog 11.5 feem pua -13.5 feem pua Chromium. Nws muaj cov hardness siab thiab lub zog, thiab tuaj yeem txhim kho ntxiv los ntawm kev kho cua sov, yog li nws tau siv dav hauv kev tsim cov riam, bearings, li qub, twj tso kua mis thiab qee qhov chaw.
430 stainless hlau (UNS S43000): 430 stainless hlau muaj li 16 feem pua -18 feem pua chromium, uas muaj qee yam corrosion kuj. Nws feem ntau yog siv rau hauv kev tsim cov khoom siv hauv tsev (xws li stainless hlau lauj kaub thiab cov tais diav), kho kom zoo nkauj sab hauv thiab qee yam khoom siv hauv tsev, thiab tsim nyog rau qee qhov kev xav tau ntawm corrosion.
Ntxiv rau qhov saum toj no ob hom stainless hlau, 400 series stainless hlau kuj suav nrog qee yam tshwj xeeb, txhua hom muaj cov tshuaj sib txawv thiab cov khoom siv kho tshuab, haum rau cov kev xav tau tshwj xeeb.
Nws yuav tsum tau muab sau tseg tias 400 series stainless hlau muaj qis corrosion kuj thiab lub zog tshaj 300 series stainless hlau.
