Dab tsi yog 430 stainless hlau?
430 stainless hlau belongs rau tsev neeg ferritic stainless hlau. Qhov no txhais tau hais tias nws raug suav hais tias muaj "mob rau qhov zoo" corrosion kuj. Qhov no yog vim muaj cov ntsiab lus chromium siab.430 stainless hlau muaj 16-18% chromium. Txawm li cas los xij, nws cov ntsiab lus nickel tsawg heev, feem ntau tsawg dua 1%. Tsis tas li ntawd, 430 stainless hlau kuj tseem muaj cov lej ntawm manganese, silicon, carbon, sulfur thiab phosphorus.
Cov tshuaj muaj pes tsawg leeg txhais tau hais tias 430 stainless hlau muaj thermal conductivity siab.
Nws yog feem ntau siv rau hauv cov ntawv thov uas yuav tsum tau muaj kev tiv thaiv corrosion, xws li tsheb txiav, cov khoom siv hauv chav ua noj, thiab cov khoom siv ua zaub mov. Vim nws qhov zoo nkauj zoo nkauj, 430 kuj tseem siv rau ntau yam kev siv kho kom zoo nkauj.
Puas yog 430 stainless hlau tsis xeb?
Zoo li txhua yam stainless hlau, 430 stainless hlau muaj ib zaj duab xis passivation uas feem ntau tiv thaiv corrosion. Qhov no yog vim cov tshuaj tiv thaiv ntawm chromium (tag nrho cov stainless hlau muaj tsawg kawg yog 10.5%) nrog oxygen los tsim ib txheej passivation (hydrated chromium oxide) uas tuaj yeem rov tsim dua yog tias muaj kev puas tsuaj.
Txawm hais tias qhov no tsis txhais tau hais tias 430 stainless hlau tsis muaj xeb, nws muaj cov ntsiab lus chromium qis dua piv rau lwm qib ntawm stainless hlau, yog li nws tsis tshua muaj kev tiv thaiv corrosion thiab paug.
Puas yog 430 stainless hlau zaub mov qib?
Cov zaub mov qib stainless hlau muaj ntau dua chromium thiab npib tsib xee, uas txhais tau hais tias 430 stainless hlau tsis suav tias yog qib zaub mov. Ntxiv dua thiab, qhov no los txo qis cov ntsiab lus chromium dua li lwm qib ntawm stainless hlau, uas ua rau nws tsis tshua muaj kev tiv thaiv corrosion thiab kev sib kis.
Thaum 430 stainless hlau yog ruaj thiab kub resistant, nws tsis haum rau kev ua zaub mov, cia los yog tuav daim ntaub ntawv vim nws tsis tshua muaj corrosion kuj thiab muaj peev xwm rau kis kab mob.
