Qhov sib txawv tseem ceeb nyob hauv qhov tseeb tias 440C stainless hlau muaj zog dua thiab muaj zog, tab sis tsis zoo corrosion kuj; thaum 316 stainless hlau, vim muaj cov molybdenum, muaj kev tiv thaiv corrosion zoo dua, tab sis nws qhov hardness tsis siab li 440C . 440C yog qhov tsim nyog rau cov ntawv thov uas xav tau siab hardness, xws li bearings thiab cov cuab yeej txiav, thaum 316 yog qhov tsim nyog rau qhov hnyav ib puag ncig xws li marine lossis chemical processing.
Dab tsi yog kev siv 440C stainless hlau?
440C stainless hlau yog sib nqus nyob rau hauv txhua yam kev mob thiab muaj kev hnav zoo heev. Nws tuaj yeem txias - ua haujlwm lossis cua sov- kho. Kev lag luam feem ntau / daim ntawv thov rau 440C stainless hlau suav nrog: bearings thiab bushings, li qub, cov cuab yeej txiav thiab cov cuab yeej.
440C Stainless hlau yog dab tsi?
440C stainless hlau yog siab - carbon martensitic stainless hlau nrog zoo heev hnav tsis kam thiab corrosion kuj. Nws boasts zoo tensile lub zog thiab lub ci ci, ua rau nws zoo tagnrho rau ntau industries, xws li tsheb, khoom noj khoom haus, khoom kho mob, thiab cov ntaub ntawv hauv tsev. Lub ntsiab kom zoo dua ntawm 440C nyob rau hauv nws hardness; piv rau lwm qib ntawm stainless hlau, nws tuaj yeem tiv taus qhov kub thiab txias, ua rau nws haum rau siab - qhov kub thiab txias ib puag ncig los yog siab - cov ntawv siv siab, xws li cov cav tov lossis cov khoom siv hluav taws xob uas yuav tsum tau hloov cov cua sov kom zoo. Tsis tas li ntawd, vim nws qhov hardness siab, 440C tuav lub ntse ntse kom ntev dua cov qib softer zoo li 316, txhais tau tias nws tuaj yeem siv rau kev txiav cov cuab yeej xws li riam tsis tas yuav ntse.
Dab tsi yog 316 Stainless Hlau?
316 stainless hlau yog austenitic stainless hlau nrog cov ntsiab lus nickel ntau dua li lwm qib. Piv nrog rau lwm qib (xws li 304 lossis 430), 316 stainless hlau muaj zog corrosion kuj, uas yog feem ntau rusting nyob rau lub sij hawm. Nws superior corrosion kuj tseem ua rau nws zoo tagnrho rau cov khoom noj khoom haus, vim nws tsis tshua muaj corroded los ntawm acidic kua. Tsis tas li ntawd, vim tias 316 stainless hlau muaj cov ntsiab lus qis dua li 440C stainless hlau, nws cov ntug tuav tsis zoo li 440C stainless hlau thaum siv los ua cov cuab yeej txiav, tab sis nws cov formability zoo dua, ua kom yooj yim rau kev ua haujlwm xws li vuam lossis dabtsi yog khoov.
