Value Collection 35574557 D-2 Tool Steel Round 1/2 in 6 Ft

Product Description

The VALUE COLLECTION 35574557 is a decarburization-free D-2 air-hardening tool steel round bar stocked at 6 feet in length with a 1/2-inch diameter. D-2 is a high-carbon, high-chromium tool steel known for its excellent wear resistance and dimensional stability during heat treatment. The decarb-free finish means the outer surface retains its carbon content, making it suitable for applications where surface integrity matters before hardening. This bar stock is used by tool and die makers, machinists, and fabricators who need reliable, predictable steel for precision work.

This round bar is suited for shop environments where D-2 tool steel is specified for dies, punches, gauges, knives, and wear-resistant tooling components. The 6-foot stock length allows for multiple cut-offs from a single piece, making it practical for short-run or prototype tooling. The air-hardening grade reduces distortion risk compared to oil-hardening alternatives, which is useful when tight dimensional tolerances must be held through the hardening process.

Key Features

• Decarb-free surface preserves carbon content at the outer diameter for reliable heat-treat results
• D-2 air-hardening grade minimizes distortion during hardening compared to oil-hardening tool steels
• 1/2-inch diameter with a tolerance of +0.005 to -0.015 inch for consistent fitment in machined applications
• 6-foot stock length allows multiple cut-off pieces per bar
• Suitable for dies, punches, wear plates, gauges, and similar precision tooling components

Compatibility

Designed as a standard D-2 air-hardening tool steel round bar for use in tool-and-die, mold-making, and general machining applications where a 1/2-inch diameter round stock is specified.

Installation Notes

Cutting and machining of tool steel should be performed by qualified machinists using appropriate tooling rated for high-carbon alloy steels. Heat treatment, including hardening and tempering, should follow established metallurgical procedures for D-2 grade steel and be performed by a qualified heat-treat facility or experienced toolmaker. Wear appropriate PPE when cutting or grinding. Always secure bar stock properly before machining to prevent movement and potential injury.
