Starrett 57634 A2 Tool Steel Flat Stock 0.75x12x18 in

Product Description

The STARRETT 57634 is an A2 air-hardening tool steel flat stock blank intended for toolmakers, die makers, and machining professionals who require precise, ready-to-machine stock. It measures 0.75 inches thick, 12 inches wide, and 18 inches long. A2 tool steel is an air-hardening, cold-work steel known for its dimensional stability during heat treatment and good wear resistance, making it a reliable choice for punches, dies, gauges, and similar tooling components. This flat stock ships in annealed condition, ready for machining prior to heat treatment.

This flat stock is suited for tool and die shops, mold makers, and production machine shops working on cold-work tooling applications. Typical uses include blanking dies, forming dies, trim dies, and precision gauging fixtures where dimensional consistency after hardening is a priority. The 12-inch by 18-inch footprint provides enough material for medium-sized tooling blanks without requiring initial rough cutting in most applications.

Key Features

• A2 air-hardening tool steel for excellent dimensional stability during heat treatment
• Thickness tolerance of +0.010 to 0.015 inches for consistent stock removal planning
• Width tolerance of +0.010 to 0.015 inches
• Length tolerance of +0.25 inches
• Square tolerance of +0.010 to 0.015 inches
• AISI Type A2 material specification for predictable hardening response

Compatibility

Designed as a general-purpose A2 tool steel flat stock blank suitable for cold-work tooling, die making, and precision machining applications where air-hardening steel is specified.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified toolmakers or machinists familiar with A2 steel properties. All grinding, milling, and EDM operations should be completed before hardening. Heat treatment should follow the material manufacturer guidelines for A2 steel austenitizing and air-quench procedures. Proper personal protective equipment is required when cutting or grinding tool steel stock.
