Stamping titanium requires mold steels with high hardness, strong wear resistance, and good toughness, as titanium has high hardness and strength, causing severe mold wear. SKD11 mold steel, after heat treatment, can reach a hardness above HRC60 and offers excellent wear resistance, but its toughness is relatively low.
DC53 mold steel, an improved version of SKD11, significantly enhances toughness while maintaining a high hardness of HRC62–63. It ensures wear resistance during titanium stamping while reducing the risk of mold cracking.
In addition, high-speed steels such as SKH-9 mold steel provide excellent red hardness, maintaining good cutting performance and hardness even when mold temperatures rise during the stamping process.
