MATERIALS TO THE GLOBAL POWER MARKET
P92 chemistry contains a Tungsten (W) addition and a reduction in Molybdenum (Mo) content, compared to P91. This Vanadium-Niobium-Boron micro alloyed steel benefits from participation strengthening due to carbides and carbonitrides precipitation which occurs during the tempering cycle.
Solid solution strengthening comes from Tungsten (W) and Molybdenum (Mo), while Tungsten-rich Laves phase precipitation is associated with increase resistance to creep. Creep resistance is the ability of a material to withstand degradation at high temperatures under a constant load—an important property in the application of power generation.
The creep resistant P92 microstructure consists of a ferritic matrix in the form of tempered martensite, free of delta ferrite. Wyman Gordon normalizes and cools P92 to result in a 100 percent martinsitic structure. The martensite is then tempered to promote carbide precipitation which results in an ideal strength and toughness combination.
