Material is P92 steel grade ASTM A335 P92, for the martensite-type heat-resistant steel, used in recent years in more coal-fired power plants, mainly the main steam pipes and pipe热蒸气again. The main alloy composition for Cr: 9%, Mo: 1% and so on. Can be used in ultra-supercritical units, more than 600 degrees Celsius.
Steel SA-335P92 in the SA-335P91 steel on the basis of the appropriate elements to reduce the Mo content, while adding a certain amount of W, Mo equivalent material (Mo +0.5 W) from the P91 steel 1% to about 1.5 %, the steel has also joined the small amount of boron, the alloy of the above-mentioned improved, with the range of 9% Cr heat-resistant steel compared to other commonly used, the high temperature corrosion and oxidation resistance, but high-temperature strength and creep performance improved.
