Value Collection PR03.0X12 A2 Tool Steel Round 3x12 in

Product Description

The VALUE COLLECTION PR03.0X12 is a decarb-free A2 air hardening tool steel round bar measuring 3 inches in diameter and 12 inches in overall length. Decarb-free stock means the outer surface retains its carbon content, eliminating the need to machine away a decarburized layer before heat treatment. This bar is supplied in stock length format and weighs approximately 24.9 pounds per foot. It is suited for tool and die shops, machining operations, and fabrication environments where A2 tool steel is specified for its air hardening characteristics and dimensional stability during heat treat.

This round bar is used in toolroom and production machining applications where A2 tool steel is required. A2 grade is commonly selected for punches, dies, gauges, forming tools, and similar components that require moderate toughness combined with good wear resistance. The 12-inch stock length is appropriate for single-part blanks or short-run tooling applications. The decarb-free condition makes this bar ready for direct machining and subsequent heat treatment without additional surface prep.

Key Features

• Decarb-free surface preserves carbon content for direct heat treatment after machining
• A2 air hardening tool steel grade offers dimensional stability and reduced distortion during hardening
• Diameter tolerance of +0.020 to +0.035 inches for consistent stock allowance
• Length tolerance of +0.250 to 0.000 inches on 12-inch stock length
• Weighs 24.9 pounds per foot for reliable mass calculations in tooling design
• Single-piece minimum order quantity suits low-volume toolroom procurement

Compatibility

Designed as a standard A2 tool steel round bar for use in toolroom, die shop, and general machining applications where air hardening tool steel stock in 3-inch diameter is specified.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with air hardening steel procedures. Follow the material manufacturer's recommended preheat, austenitizing, and air quench parameters for A2 grade. Grinding and finishing operations after hardening should account for the material's hardened state to prevent surface cracking. Proper handling equipment is advised given the weight of this bar stock.
