S7 Tool Steel

S7 Tool Steel Bar Stock

S7 tool steel is a shock-resistant, air-hardening alloy designed for
exceptional impact resistance, toughness, and high strength. Belonging to the
chromium-based hot-work tool steel family, S7 is a versatile material widely
used in the tool and die industry for demanding applications.

Key Properties of S7 Tool Steel

  • Shock Absorption: Excellent resistance to impact and sudden
    loading, making it ideal for high-stress environments.
  • Air-Hardening: Can be hardened by cooling in air, reducing
    distortion and cracking compared to oil or water quenching.
  • Hardness Range: Achieves 54–60 HRC, offering strong wear
    resistance and edge retention.
  • Machinability: Easy to machine, weld, and form using
    standard methods.

Common Applications

S7 tool steel bar stock is relied upon across industries where durability and
toughness are essential. Typical applications include:

  • Cutting and forming tools
  • Shear blades and punches
  • Chisels and hammers
  • Dies and molds exposed to impact forces

At Mozaic Precision Metals, we supply precision-ground S7
tool steel bar stock engineered for performance and reliability. With its
proven toughness and resistance to shock, S7 remains a top choice for tool and
