12Cr1MoV alloy structural steel, yog pearlitic low-alloy kub-lub zog steel, 12 hais txog cov pa roj carbon ntsiab lus ntawm 0.12%, lwm yam tshuaj muaj ntxiv rau cov hlau no xws li chromium, molybdenum, vanadium thiab lwm yam tshuaj. cov ntsiab lus, uas muaj kev tiv thaiv ntau dua rau oxidation thiab tshav kub-zog zog, qib siab ntawm cov yas tsis tu ncua, cov txheej txheem ntau lawm yog yooj yim dua, vuam kev ua tau zoo, tab sis ntau rhiab rau qhov normalizing txias.
12Cr1MoV steel yog ib qho siv dav hlau hlau uas muaj qhov kub thiab txias tsis kam, lub zog thiab oxidation tsis kam, yog li nws tau dav siv hauv roj av, tshuaj thiab hluav taws xob hluav taws xob. Txawm li cas los xij, 12Cr1MoV hlau yog nquag oxidization thiab corrosion ntawm qhov kub thiab txias, uas tsis tsuas yog cuam tshuam rau nws lub neej kev pab cuam, tab sis kuj hem kev nyab xeeb ntawm cov khoom siv. Yog li ntawd, kev kho deg ntawm 12Cr1MoV steel yog qhov tseem ceeb heev.
Cov saum npoo ntawm 12cr1mov steel kho los ntawm cov ntshav txau pom tias muaj cov qauv ntom, thiab tsis muaj txiaj ntsig zoo, thiab tsis muaj qhov zoo sib xws xws li interfacial cracks thiab pores pom. Tom qab qhov kub thiab txias oxidation kuaj xyuas, plasma txau kev kho mob ntawm 12Cr1MoV steel nto muaj cov khoom zoo antioxidant, tuaj yeem ncua qhov oxidation zoo thiab txhim kho lub neej kev pab cuam ntawm cov khoom.
