Starrett 54733 A2 Tool Steel Flat Stock 3/8x3x18 in

Product Description

The STARRETT 54733 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Measuring 0.375 inches thick, 3 inches wide, and 18 inches long, this flat stock is ground to close tolerances and manufactured to AISI A2 material specification. A2 tool steel offers excellent dimensional stability during heat treatment, making it a preferred choice for punches, dies, gauges, and precision tooling components. Licensed machinists, tool-and-die makers, and industrial maintenance personnel are the typical end users for this stock material.

This flat stock is suited for fabrication of cutting tools, forming dies, and wear-resistant components in both job shop and production environments. The air-hardening characteristic of A2 steel minimizes distortion during hardening, which is especially valuable when holding tight finished dimensions after heat treat. The stock arrives in an annealed condition, ready for machining prior to hardening. It is appropriate for low-to-medium production tooling where toughness and wear resistance are both required.

Key Features

• AISI A2 air-hardening tool steel construction for minimal distortion during heat treatment
• Thickness tolerance of +/- 0.001 inches for consistent stock removal in precision machining
• Width tolerance of +0.000 to +0.005 inches
• Length tolerance of +0.250 inches
• Square tolerance of +/- 0.001 inches
• Ships as a single piece with no minimum order multiplier beyond one unit

Compatibility

Designed as a standard AISI A2 air-hardening tool steel flat stock suitable for general toolmaking, die making, and precision machining applications requiring controlled dimensional tolerances.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified toolmakers or machinists familiar with tool steel handling procedures. Always follow established shop safety practices when cutting, grinding, or heat treating tool steel, including appropriate PPE for high-temperature operations. Heat treatment should follow the material manufacturer guidelines for A2 steel austenitizing and air-quench procedures. Consult applicable shop standards and safety codes before beginning any thermal processing.
