253MA (UNS S30815) yog lub tshav kub-resistant austenitic stainless hlau tsim rau daim ntaub ntawv uas yuav tsum tau muaj zog creep thiab zoo corrosion kuj.Nws qhov kev ua haujlwm kub yog 850 ~ 1100 ° C.
Cov tshuaj muaj pes tsawg leeg ntawm 253MA yog sib npaug, uas ua rau cov hlau muaj qhov zoo tshaj plaws kev ua tau zoo nyob rau hauv qhov kub ntawm 850 ° C-1100 ° C, siab oxidation tsis kam, oxidation kub mus txog 1150 ° C, thiab tsis tshua muaj siab creep kuj.Muaj peev xwm thiab creep rupture zog;zoo heev tiv taus kub corrosion thiab txhuam corrosion kuj nyob rau hauv feem ntau gaseous media;siab yield zog thiab tensile zog ntawm qhov kub thiab txias;zoo formability thiab weldability, thiab txaus machinability.
Ntxiv nrog rau cov ntsiab lus alloying chromium thiab npib tsib xee, 253MA stainless hlau kuj tseem muaj cov hlau tsis tshua muaj hauv ntiaj teb, yog li txhim kho nws lub peev xwm antioxidant.Nitrogen ntxiv los txhim kho cov khoom nkag thiab ua rau cov hlau no ua tiav austenite.Txawm hais tias cov ntsiab lus chromium thiab npib tsib xee tsawg, xws li cov hlau tsis muaj steel muaj nyob rau hauv ntau qhov sib txawv ntawm qhov kub thiab txias zoo li alloyed alloy steels thiab nickel puag alloys.
