摘要：
High-temperature martensitic steel P91, internationally marked GX12CrMoVNbN91, is the material used in the energy industry. Creep and high-temperature corrosion resistances are important properties that affect the application of this material at higher temperatures. Weldment reduces creep properties of construction. This work deals with the quantification of creep properties decrease in the case of material P91. The main focus is besides the evaluation of creep test results given to the mathematical description of the weld creep strength reduction. In addition metallographic analyses of weld joint after creep exposures were performed.
