Dab tsi yog T91 cov khoom siv?

A213 T91 yog cov khoom siv hlau siab alloy steel uas yog rau Asmeskas tus txheej txheem A213 / A213M. Cov khoom siv no yog siv los tsim cov kev kub kub thiab siab boiler thiab cua sov compression tshuab, thiab muaj cov yam ntxwv hauv qab no:

Siab Kub Zog: T91 Cov Khoom Taw Qhia Zoo Tshaj Plaws Cov Tshuab Cua Zoo Tshaj 600 Degree, thiab haum rau kev siv nyob rau hauv qhov chaw siab thiab siab siab.
Anti-oxidation properties: The increase in chromium content and the addition of trace nitrogen enhance the material's oxidation resistance and corrosion resistance.
Kev Ua Haujlwm Vuam: Txawm hais tias kev ua tau zoo vuam yog neeg pluag, nws tuaj yeem txhim kho los ntawm kev kho cua sov kom zoo.
Cov khoom siv no tau siv nyob rau hauv cov nroj tsuag thee
