253MA (UNS S30815) yog cov hlau tsis xeb austenitic uas tiv taus cua sov tsim los rau cov ntawv thov uas xav tau lub zog nkag siab thiab tiv taus corrosion zoo. Nws qhov kub ua haujlwm yog 850 ~ 1100 ° C.
Cov tshuaj lom neeg sib xyaw ntawm 253MA yog sib npaug, uas ua rau cov hlau muaj kev ua tau zoo tshaj plaws hauv qhov kub ntawm 850 ° C-1100 ° C, tsis kam oxidation siab heev, kub oxidation txog li 1150 ° C, thiab tsis kam nkag siab heev. Muaj peev xwm thiab lub zog tawg; zoo heev tiv taus qhov kub siab corrosion thiab txhuam corrosion tsis kam hauv feem ntau cov pa roj; muaj zog yield siab thiab tensile zog ntawm qhov kub siab; zoo formability thiab weldability, thiab txaus machinability.
Ntxiv rau cov khoom sib xyaw ua ke chromium thiab nickel, 253MA stainless hlau kuj muaj me ntsis ntawm cov hlau tsis tshua muaj, yog li ua rau nws muaj peev xwm tiv thaiv kab mob antioxidant zoo dua. Nitrogen ntxiv rau kom txhim kho cov khoom nkag thiab ua rau cov hlau no ua austenite tag nrho. Txawm hais tias cov ntsiab lus chromium thiab nickel tsawg, cov hlau tsis muaj stainless feem ntau muaj cov khoom kub siab zoo ib yam li cov hlau sib xyaw ua ke thiab cov hlau sib xyaw ua ke nickel.
