9Cr18 thiab 440C yog ob hom martensitic stainless hlau, uas txhais tau tias lawv ob leeg tau tawv los ntawm kev kho cua sov thiab paub txog lawv lub zog siab thiab kev tiv thaiv corrosion.
9Cr18 thiab440Ckoom nrog pawg ntawm martensitic stainless hlau, paub txog lawv qhov nyuaj tshwj xeeb thiab hnav tsis kam tom qab quenching, ua rau lawv haum rau kev siv hnav siab. Ob qho tib si cov ntaub ntawv 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 thiab chromium siab, ua rau nws zoo tagnrho rau kev tsim cov khoom siv uas raug hnav siab, hnyav, thiab tsis muaj corrosive ib puag ncig, xws li cov khoom siv tswj tsis siv neeg. Txawm li cas los xij, nws yooj yim rau oxidation thaum raug dej lossis dej pa, yuav tsum tau siv nws hauv ib puag ncig uas kev sib cuag nrog dej noo tsawg kawg nkaus.
Qhov sib txawv ntawm cov tshuaj lom neeg sib xyaw
| Qib | C | Cr | Mn | Si | P | S | Ni | Mo |
| 9Cr18 | 0.95-1.2 | 17.0-19.0 | 1.0 | 1.0 | 0.035 | 0.030 | 0.60 | 0.75 |
| 440C | 0.95-1.2 | 16.0-18.0 | 1.0 | 1.0 | 0.040 | 0.030 | 0.60 | 0.75 |
Hauv kev xaus,440C stainless hlaufeem ntau muaj qhov nyuaj dua thiab tiv taus corrosion zoo dua me ntsis piv rau 9Cr18, tab sis ob qho tib si cov ntaub ntawv no haum rau ntau yam kev siv uas qhov kev ua tau zoo thiab kev ua haujlwm ntev yog qhov tseem ceeb.
