S7 tool steel is a shock-resistant air-hardening steel known for its exceptional toughness and high impact strength. It is classified as a chromium-molybdenum alloy steel with additional elements such as silicon and vanadium. The alloy composition contributes to the steel's ability to withstand heavy impact loads and resist deformation at high temperatures.


Hardness: The S7 steel bar exhibits high hardness after heat treatment, making it suitable for applications requiring a durable cutting edge.

Toughness: The steel's toughness is a standout feature, providing resistance to chipping and cracking under high-stress conditions.

Wear Resistance: S7 tool steel offers good wear resistance, making it well-suited for tooling applications that involve abrasive materials or conditions.

Machinability: The machinability of S7 steel is favorable, allowing for efficient shaping and forming processes.


The S7 tool steel flat bar finds applications in a range of industries, including:

Tool and Die Making: S7 steel is commonly used in the production of punches, chisels, and forming dies due to its excellent combination of hardness and toughness.

Cold Work Applications: The S7 Shock-Resisting Tool Steel Flat Bars are suitable for cold work applications where tools may experience repeated shock and impact.

Cutting Tools: S7 flat bars are utilized in the manufacturing of cutting tools, such as shear blades and slitters, where resistance to wear and deformation is critical.

Mold Making: Alloy Steel S7 Flat Bar is employed in mold making for plastic injection molding and die casting, where toughness and wear resistance are essential.

Heat Treatment:

ASTM A681 S7 Tool & Alloy Steel Flat Bars undergo an air-hardening process, which involves heating the material to a specific temperature range and then allowing it to cool in still air. This process contributes to the steel's unique combination of hardness and toughness.

In summary, the S7 tool steel flat bar is a valuable material for applications demanding high toughness, wear resistance, and impact strength. Its versatility makes it a preferred choice in various tooling and machining scenarios, contributing to the efficiency and reliability of manufacturing processes across different industries.
