Turbine Blade Steels

Blade steel is the key material in steam turbines and gas engines. The blades are affected by high-temperature and high-pressure steam, and they are subjected to large bending moments during work. The moving blades in high-speed operation are also subjected to high centrifugal force; the blades in the wet steam zone, especially the final stage, are subjected to electrochemical corrosion. And water drop erosion. The moving blade also bears a very complicated exciting force. According to the different working environment and usage requirements, the general static blades are made of Cr13 stainless steel; the general moving blades are made of Cr13 improved stainless steel with Ni, W, Mo, V and other elements; the last one and two grades are generally made of precipitation hardening type due to the harsh working environment. Stainless steel. Higher temperature requirements for ultra-supercritical, the temperature reaches 620 ° C working environment also requires Co-W alloy materials or higher requirements.
