Stainless hlau 440C
Qib 440C stainless hlau yog cov pa roj carbon siab uas tau kho cua sov kom ua tiav qhov siab tshaj plaws, hnav tsis kam, thiab lub zog ntawm txhua qib stainless hlau. 440C steel muaj nruab nrab corrosion kuj thiab nthuav tawm qhov zoo tshaj plaws corrosion kuj nyob rau hauv hardened thiab tempered tej yam kev mob. Txawm li cas los xij, kev saib xyuas yuav tsum tau ua kom tsis txhob muaj kev kub ntxhov, uas tuaj yeem ua rau txo qis hauv nws cov corrosion kuj. Cov khoom no ua rau qib no haum rau kev siv xws li cov khoom siv valve thiab pob bearings.

Daim ntawv thov ntawm Stainless hlau 440C
Nws yog tsuas yog siv los tsim cov kabmob uas ua haujlwm nyob rau hauv ib puag ncig corrosive thiab tsis-lubricated, muaj zog oxidizing atmospheres. 440C muaj qhov zoo ntawm qhov kub thiab txias, yog li nws kuj tuaj yeem siv los ua corrosion-resistant, high-temperature bearing steel. Tsis tas li ntawd, nws kuj tseem tuaj yeem siv los tsim cov cuab yeej zoo xws li kev kho mob scalpels, txiab, nozzles, bearings, thiab lwm yam. 440C muaj peev xwm tiv taus cov loads dynamic.
