What are the requirements for the material selection of hydropower forgings?

The material selection of hydropower forgings has the following requirements:

Excellent fatigue resistance: hydropower forgings need to withstand the effects of water pressure and water flow erosion in hydroelectric power generation equipment, while ensuring high precision, high stability and long life. Therefore, the material needs to have excellent fatigue resistance.

Good corrosion resistance: water flow in hydropower equipment will have a scouring and corrosion effect on the components, so the material of hydropower forgings needs to have corrosion resistance and can resist the corrosion of water flow.

High strength and toughness: hydropower forgings need to withstand high pressure, high temperature and complex working conditions under the load, so the material needs to have high strength and toughness, can withstand a variety of complex stresses.

Good malleability: Water and electricity forgings need to be formed through the forging process, so the material needs to have good malleability, can remain stable during the forging process and is not easy to crack.

Good heat treatment performance: water and electricity forgings need to be heat treated to adjust their mechanical properties and hardness, so the material needs to have good heat treatment performance to obtain the ideal mechanical properties and hardness.

In summary, the material selection of water and electricity forgings needs to consider the factors such as fatigue resistance, corrosion resistance, high strength and toughness, malleability and heat treatment performance of the material. At the same time, factors such as the price, availability and environmental protection of materials also need to be considered.
