Value Collection 35574524 Tool Steel Round 1-1/2 in D-2

Product Description

The VALUE COLLECTION 35574524 is a decarburization-free D-2 air-hardening tool steel round bar stocked at 3 feet in length with a 1-1/2 inch diameter. D-2 tool steel is a high-carbon, high-chromium air-hardening grade known for excellent wear resistance and dimensional stability during heat treatment. The decarb-free surface condition means the outer layer retains full carbon content, reducing the need for additional stock removal before hardening. Machinists, toolmakers, and die shops rely on this material for punches, dies, gauges, and wear components requiring tight dimensional tolerances and long service life.

This round bar is suited for tool and die applications in both job shop and production environments. The stock length format makes it practical for cutting to custom lengths for individual tooling components. The +0.020 to -0.035 inch diameter tolerance supports near-net machining workflows, minimizing roughing operations. Typical end uses include blanking dies, forming tools, thread rolling dies, and precision gauging fixtures where air-hardening steel provides a lower-distortion alternative to oil or water-hardening grades.

Key Features

• Decarb-free surface retains full carbon content at the outer diameter for consistent hardness after heat treatment
• D-2 grade provides high wear resistance and dimensional stability during air-hardening cycles
• 1-1/2 inch diameter with a +0.020 to -0.035 inch tolerance supports close-tolerance machining
• 3-foot stock length allows efficient cut-to-length processing for individual tooling blanks
• Air-hardening characteristic reduces quench distortion compared to water or oil-hardening grades

Compatibility

Designed as a standard stock-length D-2 tool steel round for use in toolmaking, die making, and precision machining applications requiring an air-hardening, high-wear-resistance material.

Installation Notes

Cutting and machining of tool steel should be performed by qualified machinists using appropriate carbide or high-speed tooling rated for hardened or semi-hardened steel. Heat treatment including hardening and tempering of D-2 tool steel should be carried out by a qualified heat treater following established metallurgical procedures for this grade. Always wear appropriate PPE when cutting, grinding, or handling steel bar stock. Verify dimensional requirements and tolerances against the finished part drawing before machining to final size.
