2. Saky Steel ntim peb cov khoom hauv ntau txoj hauv kev raws li cov khoom lag luam.Peb ntim peb cov khoom nyob rau hauv ntau txoj kev, xws li,
253Ma alloy muaj cov yam ntxwv hauv qab no:
253MA yog cov cua kub-resistant austenitic stainless hlau tsim rau cov ntawv thov uas yuav tsum tau muaj zog creep thiab zoo corrosion kuj.Nws qhov kev ua haujlwm kub yog 850 ~ 1100 ° C.
Cov tshuaj lom neeg muaj pes tsawg leeg ntawm 253MA yog sib npaug, uas ua rau cov hlau muaj cov khoom zoo tshaj plaws nyob rau hauv qhov kub ntawm 850 ° C-1100 ° C, tsis tshua muaj oxidation tsis kam, thiab qhov ntsuas kub txog li 1150 ° C;tsis tshua muaj siab creep resistance Capacity thiab creep rupture zog;zoo tiv thaiv kub corrosion thiab tsis kam txhuam corrosion 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 me me ntawm lub ntiaj teb tsis tshua muaj hlau (Rare Earth Metals, REM), uas txhim kho nws cov peev xwm antioxidant.Nitrogen tau ntxiv los txhim kho cov khoom nkag thiab ua rau cov hlau no ua tiav austenite.Txawm hais tias cov ntsiab lus ntawm chromium thiab npib tsib xee yog qhov tsawg, cov hlau tsis muaj steel no muaj ntau yam zoo ib yam ntawm qhov kub thiab txias xws li cov hlau alloyed siab thiab npib tsib xee-raws li alloy.
253Ma daim ntawv thov:
253MA yog dav siv nyob rau hauv sintering khoom, blast furnace khoom, steel melting, rauv thiab nruam casting khoom, dov mills (cua sov furnaces), kho cua sov rauv thiab accessories, ntxhia khoom thiab cov khoom siv cement.
