A335 P22 yog 2.25Cr-1Mo Chromium-molybdenum kub ferritic hlau rau boilers thiab superheaters,ASTM A335/A335Mtus qauv. Xyoo 1985, nws tau hloov mus rau hauv GB5310 thiab hu ua 12Cr2MoG. Lwm lub tebchaws muaj cov qib hlau zoo sib xws, xws li Federal Republic of Germany 10CrMo910 thiab Nyiv Pooj STBA24. Hauv cr-1Mo steel series, nws lub zog thermal yog qhov siab dua, nyob rau tib qhov kub (kub≤580℃) nws lub zog tawg ntawm cov ntsia hlau thiab kev ntxhov siab uas tso cai rau nws tseem siab dua 9CR-1Mo hlau, thiab nws muaj kev ua haujlwm zoo thiab kev ua haujlwm vuam, zoo plasticity. Yog li ntawd, nws tau siv dav hauv qhov chaw ua haujlwm hnyav, xws li lub zog thermal, lub zog nuclear thiab qee cov khoom siv hydrogen hauv ntau yam kav dej cua sov thiab cov hlab ntsha siab.
Qhov kub uas tso cai: A335P22 (SA-213T22) feem ntau yog siv rau hauv 300,600MW thiab lwm lub zog loj loj boiler raj phab ntsa kub≤580℃Qhov kub ntawm lub tshuab cua sov thiab lub raj phab ntsa & LT; 540℃phab ntsa cov yeeb nkab thiab lub taub hau, hom hlau no tau siv dav hauv Tebchaws Meskas, Nyiv Pooj thiab Tebchaws Europe, muaj keeb kwm ntev ntawm kev ua haujlwm hauv cov chaw tsim hluav taws xob, yog qhov ua tau zoo ruaj khov, kev ua haujlwm zoo ntawm cov hlau laus.
12Cr1MoV hlau yog chromium-molybdenum vanadium hlau vanadium hlau, feem ntau yog siv rau 12Cr1MoV / GB5310 steel yeeb nkab. Siv dav, yog qhov kub thiab txias hauv 480℃~580℃thaj chaw kub siab nrog ib qho ntawm cov ntaub ntawv tshaj plaws. 12Cr1MoVG steel tube kev pabcuam kub: nws yog siv rau cov hlau tseem ceeb ntawm superheater tube, header thiab chav yeeb nkab ntawm lub boiler siab uas nws lub raj phab ntsa kub tsawg dua lossis sib npaug rau 580℃.
