    MATERIALS，PERFORMANCE

    Fundamental Requirements:

    Excellent weld compatibility with filaments
    Superior machinability,Post-heat.
    treatment hardness:HRC 28-35(medium-low range)
    Excellent welding performance and machinability. The hardness of the impeller material after heat treatment should be selected as medium or low hardness.

    The choice of materials mainly depends on the operating temperature conditions.
