Description

technical field [0001] The invention relates to a steam turbine blade, in particular to an oxidation-resistant steam turbine blade. Background technique [0002] The blade of the steam turbine is an indispensable part of the steam turbine, the blade of the steam turbine. Commonly used materials for steam turbine blades are: (1): Chromium stainless steel 1Cr13 and 2Cr13 are martensitic heat-resistant steels, which not only have sufficient strength at room temperature and working temperature, but also have high corrosion resistance and vibration reduction. It is the most widely used steam turbine material in the world. (2): Reinforced chromium stainless steel It makes up for the disadvantage of low thermal strength of 1Cr13 chromium stainless steel, and adds molybdenum, tungsten, vanadium, niobium, boron, etc. to it. (3): Low-alloy pearlitic heat-resistant steel is used to manufacture moving blades and stationary blades at all levels of medium-pressure steam turbines with op...
