GB/T 3077 12Cr1MoV alloy steel plate is a steel grade widely used in high-pressure, ultra-high pressure, subcritical power station boiler superheaters, headers and main steam ducts. It still has high thermal strength and oxidation resistance at 580°C, andWhen did GB / T 3077 steel supersede 1999 steel?GB/T 3077-2015 Alloy structure steels will supersede GB/T 3077-1999 Alloy structure steels from November 1, 2016.See all results for this questionWhat kind of heat treatment is needed for 4340 steel?The high hardness of 4340 alloy steel requires that the material be welded in the annealed or tempered state and then heat treated to resist martensite formation and cold cracking. However, as in motor shaft applications, under quenching and tempering conditions, 4340 steel typically use high preheating in low hydrogen processes.See all results for this question
