Starrett 54593 A2 Tool Steel Flat Stock 0.125x2.5x18 in

Product Description

The STARRETT 54593 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a reliable, dimensionally consistent raw material for punches, dies, gauges, and similar precision tooling applications. This flat stock measures 0.125 inches thick, 2.5 inches wide, and 18 inches long, with a weight of 1.59 pounds per piece. Manufactured to AISI A2 tool steel specification, it offers good dimensional stability during heat treatment and is suited for applications requiring moderate toughness combined with wear resistance. Thickness tolerance is held to plus or minus 0.001 inches, supporting close-tolerance tooling work from the raw stock stage.

A2 air-hardening flat stock is commonly used in tool and die shops, maintenance and repair operations, and precision fabrication environments. It is appropriate for both production toolmaking and prototype work where consistent cross-section dimensions reduce setup and grinding time. The 18-inch length allows multiple blanks to be cut from a single piece for smaller tooling components. This stock is typically purchased by toolmakers, machinists, and industrial maintenance professionals working in job shops, manufacturing plants, and fabrication facilities.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate cutting fluids and tooling rated for hardened or semi-hardened steel. Heat treatment to full hardness should be performed by a qualified heat treater following AISI A2 recommended cycles. Always wear appropriate PPE including eye protection and cut-resistant gloves when handling and cutting flat stock. Consult applicable shop safety standards before beginning any machining or heat-treating operations.
