440C Stainless Hlau Bar
Kev Piav Qhia Luv:
440C stainless hlau yog cov hlau martensitic uas muaj cov pa roj carbon ntau uas paub txog nws qhov nyuaj heev, hnav tsis kam, thiab tiv taus corrosion.
Cov Hlau Stainless 440C Tuav:
440C stainless hlau tuaj yeem ua kom tawv kom tau qib siab ntawm qhov tawv, feem ntau nyob ib puag ncig 58-60 HRC (Rockwell hardness scale). Nws yog ib feem ntawm 400 series ntawm stainless hlau, uas yog tus yam ntxwv los ntawm kev muaj cov pa roj carbon ntau, feem ntau nyob ib puag ncig 0.60-1.20%, thiab tiv taus corrosion nruab nrab. Nws muaj kev tiv taus hnav zoo heev, ua rau nws tsim nyog rau cov ntawv thov xws li bearings, cov cuab yeej txiav, cov cuab yeej phais, thiab cov khoom siv valve. Txawm hais tias tsis tiv taus corrosion zoo li austenitic stainless hlau (piv txwv li, 304, 316), 440C muaj kev tiv taus corrosion zoo hauv qhov chaw sov. Nws yog corrosion ntau dua li lwm cov hlau carbon siab vim nws cov ntsiab lus chromium. 440C stainless hlau tuaj yeem kho cua sov kom ua tiav cov khoom siv kho tshuab xav tau.
