09CuPCrNi yog cov huab cua huab cua tsim los tiv thaiv atmospheric corrosion thiab muab lub zog siab thiab zoo toughness. Nws yog feem ntau siv nyob rau hauv kev tsim kho kev lag luam ntawm cov qauv xws li txuas hniav, cov tsev thiab lwm yam khoom siv sab nraum zoov uas raug rau huab cua hnyav.
Cov muaj pes tsawg leeg ntawm 09CuPCrNi steel feem ntau muaj alloying ntsiab xws li tooj liab, chromium thiab npib tsib xee, uas pab txhim kho nws corrosion kuj. Cov ntsiab lus no cuam tshuam nrog cov huab cua los tsim cov txheej txheem tiv thaiv xeb uas pab tiv thaiv corrosion ntxiv ntawm cov hlau.
