A335 P22 yog 2.25Cro chromium-molybdenum high kub ferritic steel rau boilers thiab superheaters,ASTM A335 / A335MTxheem. Xyoo 1985, nws tau hloov mus rau GB5310 thiab npe hu ua 12cr2mog. Lwm lub teb chaws muaj cov qib tshiab zoo sib xws, xws li tsoomfwv Republic ntawm lub teb chaws Yelemees 10crmo910 thiab Nyiv Stba24. Hauv CR-1MO steel series, nws lub thermal muaj zog yog qhov tseem ceeb, nyob rau hauv tib tug kub tib yam (kub≤580℃) Nws cov ntsia hlau ua kom muaj zog thiab cov kev ntxhov siab uas muaj kev ntxhov siab ntau dua li 9cr-1mo steel, thiab nws muaj kev ua tau zoo thiab ua kom zoo nkauj, zoo ruaj khov plastity. Yog li ntawd, nws tau siv dav hauv kev ua haujlwm hnyav, xws li thermal zog ua haujlwm, lub zog hollar thiab qee cov khoom siv hydrogen hauv ntau cov pa hluav taws xob thiab cov nkoj siab siab.
