  • High Hardness & Wear Resistance

    Achieves HRC 50–55 after quenching. Superior edge retention compared to 410, ensuring long-lasting performance for cutting tools.

  • Optimized Heat Treatment

    Strength and toughness can be precisely adjusted via quenching (950–1000℃) + tempering (200–300℃). Reliable hardness consistency for CNC machining.

  • Better Corrosion Resistance

    12–14% Cr content. Optimized for humid environments, providing a cost-effective alternative to tool steel with lower maintenance requirements.
