Abstract

Abstract: Tensile test, creep test and linear expansion coefficient test of martensitic stainless steel FV520B at medium and high temperature were carried out by means of electronic universal testing machine, thermal dilatometer and other testing and analysis methods, and the fracture of the specimen was observed by means of SEM. The results show that the tensile properties of FV520B steel at medium and high temperatures are lower than those at room temperature. When the test temperature rises from 300 ℃ to 500 ℃, the strength decreases as a whole, but the plasticity is basically stable. The FV520B steel aged at 480 ℃ has good creep resistance at test temperature of 300 ℃ and load of yield strength. In the range of 300-500 ℃, the linear expansion rate of the FV520B steel presents a gentle growth trend.

Key words: FV520B steel, medium and high temperature, tensile properties, creep resistance, linear expansion coefficient
