There are many types of pumps and their applications are very extensive. Almost all industries are inseparable from them. The valve is a very important part (one of the main wearing parts) in the pump, which will directly affect the working performance and service life of the pump. Therefore, it is necessary to put forward higher requirements for its materials. In addition to good comprehensive mechanical properties, it also needs to have relatively high strength and hardness. 

The advantage of Stellite alloy is that it has high hardness and toughness, and at the same time can achieve corrosion resistance, high temperature resistance and wear resistance, which can just meet its performance and use requirements.
