9CR18 thiab 440C yog ob hom martensitic stainless hlau, uas txhais tau tias lawv yog ob qho nyuaj los ntawm kev kho cua sov thiab paub rau lawv lub zog siab thiab corrosion tsis kam.
9CR18 thiab440CMuaj rau cov qeb ntawm martensitic stainless hlau, muaj kev tiv thaiv zoo rau lawv cov kev ua kom muaj zog tshwj xeeb thiab hnav tsis kam tom qab kev txiav txim siab rau kev hnav zoo. Ob cov ntaub ntawv puas tuaj yeem ua tiav qib harc60 ° thiab cov ntsiab lus roj carbon monoxide rau cov khoom lag luam kub, thiab cov khoom siv hnyav, xws li tsis siv neeg tswj hwm Valve Qhov Chaw. Txawm li cas los xij, nws yog qhov ntxim rau oxidation thaum raug dej los yog dej vapor, yuav tsum siv nyob rau hauv ib cheeb tsam uas muaj kev sib cuag nrog noo noo yog tsawg.
Qhov sib txawv ntawm cov tshuaj lom neeg
| Teem nqi | 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 cov ntsiab lus xaus,440C Stainless HlauFeem ntau muaj cov hardness ntau dua thiab me ntsis zoo dua corrosion tsis kam piv rau 9CR18, tab sis ob yam ntaub ntawv tsim nyog rau ntau cov kev siv ntawm cov kev ua tau zoo thiab kav ntev yog qhov tseem ceeb.
