1Cr5Mo steel yog martensitic hlau qauv.1Cr5Mo muaj oxidation zoo nyob ib ncig ntawm 650 degree, zoo thermal zog hauv qab 600 degree, thiab zoo vibration damping thiab thermal conductivity.1Cr5Mo steel yog dav siv nyob rau hauv chav turbines.15CrMo steel phaj yog cov cua sov-resistant steel. nrog pearlitic qauv.15CrMo steel phaj yog lub tshav kub-resistant steel nrog pearlitic qauv.
15CrMo steel phaj yog ib hom kev kub-resistant steel nrog pearlitic qauv, nrog siab thermal zog (δb Ntau tshaj los yog sib npaug rau 440MPa) thiab kub-kub oxidation tsis kam, thiab ib co degree ntawm hydrogen corrosion kuj. Vim cov ntsiab lus siab ntawm Cr, C thiab lwm yam alloying ntsiab nyob rau hauv cov hlau, cov hlau hardening nyiam yog pom tseeb, thiab cov weldability tsis zoo.
