Drill Rod Tool Steels 03719598 A2 Flat Stock 3/8x1x36 in

Product Description

The DRILL ROD TOOL STEELS 03719598 is an A2 air-hardening tool steel flat stock bar measuring 3/8 inch thick, 1 inch wide, and 36 inches long. A2 tool steel is a chromium-molybdenum alloy known for its dimensional stability during air hardening and its balance of toughness and wear resistance. This flat stock is supplied in the annealed condition and is ready for machining, grinding, or fabrication before heat treatment. It is used by tool and die makers, machinists, and metalworking professionals who need a reliable, machinable blank for dies, punches, gauges, and fixture components.

A2 air-hardening flat stock is a standard choice for toolroom applications in both job shops and production environments. The 36-inch length and 3/8 by 1 inch cross-section suits a wide range of blanking die components, forming tools, and precision fixtures. Because A2 steel air-hardens with minimal distortion compared to oil-hardening grades, it is frequently specified where dimensional accuracy after heat treat is critical. This bar is appropriate for light to medium production tooling and is a common stock item for custom tool fabrication.

Key Features

• A2 air-hardening tool steel: minimal distortion and good dimensional stability during heat treatment
• 3/8 inch thickness with a controlled tolerance of +0.010 to +0.015 inches
• 1 inch width with a tolerance of +0.010 to +0.015 inches
• 36 inch length with a tolerance of +0.250 to +0.500 inches
• Square tolerance of +/- 0.003 inches for consistent cross-section geometry
• AISI Type A2 material specification for standardized alloy composition

Compatibility

Designed as a standard-profile A2 tool steel flat stock bar suitable for machining into dies, punches, gauges, fixture components, and other precision toolroom applications where air-hardening steel is specified.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists using appropriate tooling for hardened or semi-hard steel as applicable. Heat treatment to full hardness requires an oven-controlled atmosphere or vacuum furnace and should follow AISI A2 recommended austenitizing and tempering procedures. Wear appropriate personal protective equipment when cutting or grinding. Material should be stored in a dry environment to prevent surface oxidation.
