12Cr1MoV kub dov steel ntawv

12Cr1MoV round steel muaj ntau dua oxidation tsis kam thiab thermal zog. Lub creep txwv ntawm cov hlau no yog ze heev rau tus nqi ntawm lub zog endurance, thiab nws muaj plasticity siab nyob rau hauv cov ntaub ntawv ntawm mus tas li nro; cov hlau muaj kev tsim khoom zoo thiab weldability, tab sis nws yuav tsum tau preheated rau 300 ° C ua ntej vuam thiab kev ntxhov siab tom qab vuam. deal nrog. Nws yog qib steel dav siv hauv high-pressure, ultra-high pressure, subcritical power station boiler superheaters, headers thiab main steam ducts. Nws tseem muaj lub zog thermal thiab oxidation tsis kam ntawm 580 ° C, thiab 12Cr1MoV steel phaj muaj cov yas zoo dua qub. 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 ntev ntawm 580 ° C yuav tsim pearlite spheroidization.
