Starrett 57593 A2 Tool Steel Flat Stock 5/16x2.5x18 in

Product Description

The STARRETT 57593 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Measuring 5/16 inches thick, 2-1/2 inches wide, and 18 inches long, this flat stock ships in the annealed condition and is designed for subsequent heat treatment by the end user. A2 tool steel offers good dimensional stability during air hardening and solid wear resistance, making it a reliable choice for punches, dies, and cutting tools. Machinists, tool and die makers, and industrial fabricators work with this material in job shop and production environments.

This flat stock is suited for fabricating precision tooling components in both job shop and production settings. The 5/16 inches thickness and 2-1/2 inches width provide a workable cross-section for a wide range of tool and die blanks. At 18 inches in length, the bar yields multiple blanks per piece depending on the finished part size. Material conforms to AISI Type A2 specification, appropriate for applications requiring moderate toughness and good wear resistance after hardening.
