Value Collection 35574730 Tool Steel Round 1-3/8 in S-7

Product Description

The VALUE COLLECTION 35574730 is a decarburization-free S-7 Hi-Shock tool steel round bar in a stock 3-foot length. S-7 is an air- or oil-hardening shock-resisting tool steel known for high impact toughness and moderate wear resistance, making it well-suited for tooling, punches, chisels, and die components that absorb repeated impact loads. The bar measures 1-3/8 inches in diameter with a ground tolerance of +0.005 to -0.015 inches. The decarb-free condition means the outer surface retains its carbon content, reducing the need to remove significant material before heat treating or machining to final dimensions.

This round bar stock is used in tool rooms, machine shops, and maintenance departments across manufacturing, fabrication, and heavy industrial environments. It is a standard stock-length bar suitable for cutting to custom lengths for tooling blanks, pins, drivers, forming tools, and other impact-resistant components. Machinists and tool-and-die makers typically source this bar for applications where a tougher, more shock-resistant steel is required than standard cold-work grades like D2 or A2.

Key Features

• S-7 Hi-Shock tool steel grade offers high impact toughness with good machinability before hardening
• Decarb-free condition preserves surface carbon content for consistent heat treat response
• 1-3/8 inch diameter with tight tolerance of +0.005 to -0.015 inches for predictable stock removal
• 3-foot stock length allows efficient cut-to-length use with minimal waste
• Suitable for punches, chisels, forming tools, and other high-impact tooling applications

Compatibility

Designed as a general-purpose S-7 tool steel round bar for tool room and machining applications requiring a decarb-free, shock-resisting steel in a standard stock length.

Installation Notes

Cutting and machining of tool steel should be performed by qualified machinists using appropriate coolant and tooling rated for alloy steels. Heat treatment of S-7 should follow established metallurgical guidelines for austenitizing temperature, quench media, and tempering cycles specific to the intended hardness range. Always wear appropriate PPE when cutting or grinding tool steel bar stock. Verify finished dimensions after any heat treat operation, as distortion may occur.
