Cov qib no muaj 25% chromium thiab 20% npib tsib xee, ua rau lawv tiv taus oxidation thiab corrosion.Qib 310S yog qhov qis dua cov pa roj carbon monoxide, tsis tshua muaj siab rau embrittlement thiab rhiab heev hauv kev pabcuam.Lub siab chromium thiab nruab nrab nickel cov ntsiab lus ua rau cov hlau no muaj peev xwm rau kev siv hauv kev txo cov sulfur cua uas muaj H2S.Lawv tau dav siv nyob rau hauv nruab nrab carburising atmospheres, raws li tau ntsib nyob rau hauv petrochemical ib puag ncig.Rau qhov hnyav dua carburising atmospheres lwm cov cua sov uas tiv thaiv cov hlau yuav tsum tau xaiv.Qib 310 tsis pom zoo rau cov kua quenching ntau zaus vim nws raug kev kub ntxhov.Qib feem ntau yog siv rau hauv cov ntawv thov cryogenic, vim nws qhov toughness thiab qis sib nqus permeability.
Hauv kev sib piv nrog lwm cov austenitic stainless hlau, cov qib no tsis tuaj yeem ua kom tawv los ntawm kev kho cua sov.Lawv tuaj yeem ua haujlwm hnyav los ntawm kev ua haujlwm txias, tab sis qhov no tsis tshua muaj kev xyaum.
