Abstract :

 According to common forecast the worldwide demand for power will increase significantly after next two decades and the current power plant need to double power. Steam turbine blade plays important role. The efficiency of steam turbine is dependent on material of blades, shape of blades and angle of blade. So, the material of turbine blade plays a vital role in steam turbine. The material blade should posses maximum yield strength, corrosion property, material damping etc. The main objective of this paper is to discuss different material as candidates for turbine blade. After the material selection the turbine blade analysis can be done by ANSYS. For this we take a SST-200 turbine model.
