Starrett 54761 A2 Tool Steel Flat Stock 0.625x2.5x18 in

Product Description

The STARRETT 54761 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Manufactured to AISI A2 specification, this flat stock measures 0.625 inches thick, 2.5 inches wide, and 18 inches long, with a weight of 7.94 pounds. A2 tool steel offers good dimensional stability during heat treat and strong wear resistance, making it a dependable choice for punches, dies, gauges, and similar toolroom components. Machinists and tool-and-die makers work this material in the annealed state before hardening.

This flat stock is suited for general toolroom use in job shops, manufacturing facilities, and maintenance departments where close-tolerance tool steel stock is required. The 18-inch length is practical for shorter tooling blanks and can be cut to size before or after heat treatment. A2 air-hardening steel is commonly selected when oil-quench distortion is a concern, as it hardens in still or forced air, reducing the risk of warping on thinner cross-sections. No specific compatible equipment models are stated for this raw stock item.

Installation Notes

Cutting, grinding, and machining should be performed by qualified machinists or tool-and-die makers using appropriate coolant and tooling for tool steel. Heat treatment should follow established AISI A2 procedures for austenitizing temperature, soak time, and air-cool cycle; consult the material specification or a qualified heat treater before processing. Always use proper personal protective equipment when cutting or grinding tool steel stock.
