440C Stainless Hlau Bar
Lus piav qhia luv luv:
440C stainless hlau yog cov pa roj carbon ntau martensitic stainless hlau uas paub txog nws zoo heev hardness, hnav tsis kam, thiab corrosion kuj.
Stainless hlau 440C Bars:
440C stainless hlau tuaj yeem ua kom tawv tawv kom ua tiav cov qib siab hardness, feem ntau nyob ib puag ncig 58-60 HRC (Rockwell hardness scale).It belongs rau 400 series ntawm stainless hlau, uas yog tus cwj pwm los ntawm cov ntsiab lus siab carbon, feem ntau nyob ib ncig ntawm 0.60-1.20%. , thiab nruab nrab corrosion kuj.Nws muaj kev hnav zoo heev, ua rau nws tsim nyog rau kev siv xws li bearings, txiav cov cuab yeej, cov cuab yeej phais, thiab cov khoom siv valve.Thaum tsis muaj corrosion-resistant li austenitic stainless hlau (xws li 304, 316), 440C muaj kev tiv thaiv corrosion zoo hauv qhov chaw me me. Nws yog corrosion resistant ntau dua li lwm cov high-carbon steels vim nws cov ntsiab lus chromium.440C stainless hlau tuaj yeem kho cua sov kom ua tiav cov khoom siv kho mob uas xav tau.

Nta & Cov txiaj ntsig:
•Tom qab kev kho cua sov kom tsim nyog, 440C stainless hlau tuaj yeem ua tiav qib siab ntawm hardness, feem ntau ntawm 58-60 HRC, ua rau nws tsim nyog rau cov ntawv thov uas yuav tsum tau muaj zog hardness.
•Vim nws cov ntsiab lus carbon siab thiab cov khoom siv kho cua sov zoo heev, 440C stainless hlau nthuav tawm zoo hnav tsis kam, ua rau nws haum rau ntau yam kev siv xws li cov cuab yeej txiav, bearings, thiab lwm yam.
•Txawm hais tias tsis yog corrosion-resistant li austenitic stainless hlau (xws li, 304, 316), 440C stainless hlau tseem muaj corrosion kuj zoo nyob rau hauv ib puag ncig haum, feem ntau vim nws cov ntsiab lus chromium siab, uas tsim ib qho kev tiv thaiv chromium oxide txheej txheej.
•440C stainless hlau tuaj yeem ua haujlwm zoo nyob rau hauv cov xwm txheej tsim nyog kom tau raws li ntau yam kev xav tau. Txawm li cas los xij, vim nws cov hardness siab thiab lub zog, machining tej zaum yuav nyuaj thiab yuav tsum tau tsim cov txheej txheem machining thiab cov cuab yeej.
•440C stainless hlau ua kom pom qhov zoo ntawm qhov kub thiab txias, tswj nws qhov hardness thiab hnav tsis kam nyob rau hauv qhov kub thiab txias, ua rau nws tsim nyog rau kev siv hauv qhov kub thiab txias.
•Cov khoom siv hluav taws xob ntawm 440C stainless hlau tuaj yeem hloov kho los ntawm kev kho cua sov, xws li hardness, lub zog, thiab toughness, kom tau raws li cov kev thov tshwj xeeb.
