Creep Properties of Base Material and Weldments of P23 Steel

Original language description

For construction of waterwalls are used low alloy 2,25Cr steel because of absence of necessarity of post weld heat treatement. Steels such as T12 or T22 can not be used more for their low creep strength. Up to 560-580°C is able to use new low-alloy steels like T23 and T24. Their benefits are better fabrication, allowing welding without PWHT and lower price in comparison to modified 9 12% Cr steels. Characteristics of T23 steel used for thin tubes are known. However, thick section can not be welded without PWHT. Properties of P23 and their weldments, that is used for thick pipes, are discussed in this article.
