Starrett 57563 A2 Tool Steel Flat Stock 5/32x1-1/2x18 in

Product Description

The STARRETT 57563 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a reliable, dimensionally consistent blank for custom tooling fabrication. This flat stock measures 5/32 inch thick by 1-1/2 inches wide by 18 inches long and ships in annealed condition, ready for machining prior to heat treatment. A2 tool steel offers good wear resistance and dimensional stability during air-hardening, making it a common choice for punches, dies, gauges, and similar precision tools. The piece weighs approximately 1.2 pounds.

This flat stock is suited for tool rooms, machine shops, and maintenance departments fabricating or repairing tooling components. It is used in applications where controlled air-hardening is preferred over oil or water quench, reducing the risk of distortion in finished parts. The 18-inch length provides adequate stock for most small-to-medium tool blanks, and the pre-sized width and thickness minimize raw material removal before rough machining begins.

Compatibility

Designed as a general-purpose A2 tool steel flat stock blank for use in standard tool room and machining applications requiring air-hardening material in this size range.

Installation Notes

This material is typically machined in its annealed state before hardening. Hardening and tempering of A2 tool steel should be performed by a qualified heat treater or tool room professional following the material specification procedures for AISI A2. Always use appropriate personal protective equipment when cutting, grinding, or machining tool steel. Consult the material specification and applicable shop safety standards before processing.
