How to select suitable mold materials for high-speed stamping of spacecraft parts?

      Selecting the right die material for high-speed stamping of spacecraft parts requires consideration of several factors, and the following are some key selection points:
    Strength and hardness
        High strength and hardness should be available to withstand the tremendous pressure and wear of the high-speed stamping process. For example, cemented carbides such as tungsten-cobalt tungsten carbide (YG type) have high hardness and compressive strength.

    Wear resistance
        Good wear resistance is critical to ensure that the mold maintains its accuracy over a long period of time. High-speed steels such as powdered high-speed steels (e.g. ASP series) usually have excellent wear resistance.
    Toughness
        Mold materials should have a certain degree of toughness to prevent brittle fracture during the stamping process. Alloy tool steels (e.g. Cr12MoV, etc.) have good toughness while maintaining hardness.

    Thermal stability
        Because of the heat generated by high-speed stamping, the material needs to have good thermal stability, at high temperatures can still maintain its performance. Hot work die steels (e.g. H13, etc.) are commonly used in high-temperature working environments.

    Dimensional stability
        During the stamping process and subsequent heat treatment, the material should maintain dimensional stability to ensure the accuracy of the mold.
    Purity
        High purity material can reduce inclusions and defects and improve the reliability of the mold.
