9Cr18 thiab 440C yog ob hom martensitic stainless hlau, uas txhais tau hais tias lawv yog ob qho tib si hardened los ntawm kev kho cua sov thiab paub txog lawv lub zog siab thiab corrosion kuj.
9c18 ua440c uabelongs rau qeb ntawm martensitic stainless hlau, renowned rau lawv tshwj xeeb hardness thiab hnav tsis kam tom qab quenching, ua rau lawv haum rau high-hnav daim ntaub ntawv. Ob qho khoom siv tuaj yeem ua tiav qib hardness ntawm HRC60 ° thiab siab dua tom qab kev kho cua sov.9Cr18 yog tus cwj pwm los ntawm nws cov pa roj carbon ntau thiab chromium cov ntsiab lus, ua rau nws zoo tagnrho rau kev tsim cov khoom uas raug hnav, hnyav hnyav, thiab tsis muaj corrosive ib puag ncig, xws li kev tswj tsis siv neeg. valve qhov chaw. Txawm li cas los xij, nws muaj kev cuam tshuam rau oxidation thaum raug dej los yog dej vapor, yuav tsum tau siv nws nyob rau hauv ib puag ncig uas muaj kev sib cuag nrog noo noo tsawg.
Qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg

Hauv cov ntsiab lus,440C stainless hlauFeem ntau muaj cov hardness siab dua thiab zoo dua corrosion kuj piv rau 9Cr18, tab sis ob qho tib si cov ntaub ntawv tsim nyog rau ntau yam kev siv uas ua haujlwm siab thiab ua haujlwm ntev yog qhov tseem ceeb.
