12Cr1MoVG ke tšepe ea boleng bo holimo ea chromium-molybdenum-vanadium alloy e khetholloang ka matla a phahameng, khanyetso e ntle ea creep, le ho bola ho matla le ho hanyetsa oxidation. Ha e bapisoa le 15CrMoG, e eketsa palo e nyane ea vanadium (V), e leng ho ntlafatsang ho hanyetsa mocheso o phahameng le botsitso.
