GB/T3077 12Cr1MoV Alloy Structure Steel Bars
12Cr1MoV puag ncig bar yog tus qauv steel qib rau kev ua raws li Tuam Tshoj tus qauv hauv lub tebchaws. Nws yog cov khoom siv hlau alloy thiab cov hlau tsis muaj cua sov. Cov hlau no tseem muaj lub zog thermal thiab oxidation tsis kam ntawm 580 degree, thiab muaj cov yas ntev ntev. Cov txheej txheem ntau lawm yog qhov yooj yim thiab kev ua haujlwm vuam yog qhov zoo, tab sis nws yog rhiab heev rau qhov normalizing cua txias. Kev siv mus sij hawm ntev ntawm 580 degree yuav tsim qhov thib ob ntawm temper brittleness tshwm sim los ntawm kev sib cais ntawm impurity ntsiab xws li phosphorus ntawm cov ciam teb. Kev siv mus ntev kuj yuav ua rau pearlite spheroidization.

Cov yam ntxwv tseem ceeb ntawm 12Cr1MoV steel puag ncig bar
Piv nrog 12CrMoV steel, cov hlau no muaj ntau dua oxidation tsis kam thiab thermal zog. Lub creep txwv ntawm cov hlau no yog ze heev rau cov nqi zog, thiab nws muaj plasticity siab nyob rau hauv enduring tensile tej yam kev mob. Cov hlau muaj kev ua tau zoo thiab weldability, tab sis nws yuav tsum tau preheated rau 300 degree ua ntej vuam thiab kev ntxhov siab tom qab vuam.
Nws yog cov khoom siv hlau dav siv hauv superheaters, headers, thiab cov kav dej tseem ceeb ntawm cov high-pressure, ultra-high-pressure, thiab subcritical power station boilers. Nws tseem muaj lub zog thermal, oxidation tsis kam thiab cov yas ntev ntev ntawm 580 degree. Cov txheej txheem ntau lawm yog qhov yooj yim thiab kev ua haujlwm vuam yog qhov zoo, tab sis nws yog rhiab rau qhov normalizing cua txias. Yog tias siv rau lub sijhawm ntev ntawm 580 degree, qhov thib ob ntawm temper brittleness yuav tshwm sim vim kev sib cais ntawm impurities xws li phosphorus ntawm cov ciam teb. Pearlite spheroidization tseem yuav tshwm sim nrog kev siv mus ntev.
