15CrMoR belongs rau chromium-molybdenum alloy steel rau cov hlab ntsha siab, sib haum rau American Standard SA387Gr12CL2 (ASME), cov khoom no feem ntau yog siv rau kev tsim cov petrochemical loj, tsim hluav taws xob thermal thiab lwm yam lag luam, xws li cov hlab ntsha siab, xws li reactors, tshav kub exchangers, separators thiab hais txog.
15CrMoR steel phaj siv tus qauv: GB / T 713. 713-2014 thiab GB/T35012-2018 tus qauv, tus qauv tshiab 2024 Lub Peb Hlis pib siv, tam sim no tus qauv yog GB/T713- 2014.
15CrMoR steel phaj smelting: 15CrMoR steel phaj yog smelted los ntawm oxygen converter thiab hluav taws xob rauv, thiab yuav tsum tau refined sab nraum lub cub tawg. Lub compression piv ntawm nruam casting billet thiab ingot yog tsis tsawg tshaj li 3; qhov compression ratio ntawm electroslag remelting billet tsis tsawg tshaj 2.
Tensile xeem: thickness 6 ~ 60mm yield zog ntau dua los yog sib npaug rau 295MPa, tensile lub zog ntawm 450 ~ 590MPa thickness ntau dua 60 ~ 100mm yield zog ntau dua los yog sib npaug rau 275MPa, tensile zog ntawm 450 ~ 590MPa thickness 0 ntau dua 10 hli lub zog ntau dua los yog sib npaug rau 255MPa, tensile zog ntawm 440 ~ 580MPa
Daim ntawv thov Scope ntawm 15CrMoR steel phaj: 15CrMoR steel phaj feem ntau yog siv los tsim cov petrochemical loj, tsim hluav taws xob thermal thiab lwm yam kev lag luam ntawm cov hlab ntsha siab, xws li reactors, tshav kub exchangers, separators thiab lwm yam. Nws muaj qhov zoo heev hydrogen sulphide corrosion tsis kam, ua haujlwm kub thiab txias thiab kev ua haujlwm vuam.
