Starrett 57495 A2 Tool Steel Flat Stock 0.0625x2.5x18 in

Product Description

The STARRETT 57495 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, punches, and precision machining applications. This flat stock measures 0.0625 inches thick, 2.5 inches wide, and 18 inches long, with a weight of 0.8 pounds. It is manufactured to tight tolerances: plus or minus 0.001 inches on thickness and squareness, plus 0.000 to 0.005 inches on width, and plus 0.250 inches on length. A2 tool steel offers good wear resistance and dimensional stability through the air-hardening heat treatment process, making it a reliable choice for fabricating cutting tools, fixtures, and gauges.

This flat stock is suited for tool and die shops, machine shops, and maintenance departments that require consistent material stock for custom tooling and precision components. The air-hardening A2 grade is commonly selected when machinists need moderate toughness combined with good wear resistance. It can be machined in the annealed state and then air hardened to working hardness. Typical users include tool and die makers, machinists, and industrial maintenance professionals working in both job shop and production environments.

Installation Notes

Machining and grinding should be performed in the annealed state before heat treatment. Heat treatment of A2 tool steel should be carried out by a qualified tool and die maker or heat-treat professional following the material specification guidelines for AISI A2. Appropriate personal protective equipment and shop safety practices apply when cutting or grinding tool steel stock. Always verify final dimensions after heat treatment, as some dimensional change may occur.
