Starrett 57519 A2 Tool Steel Flat Stock 3/16x3/4x18 in

Product Description

The STARRETT 57519 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Measuring 3/16 inches thick, 3/4 inches wide, and 18 inches long, this flat stock is manufactured to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus or minus 0.001 inches on squareness, plus 0.000 to 0.005 inches on width, and plus 0.250 inches on length. A2 tool steel is valued for its balanced combination of wear resistance and toughness after air-hardening heat treatment. Machinists and tool and die makers stock this material for fabricating punches, dies, gauges, and cutting tools.

This flat stock is suited for job shops, tool rooms, and maintenance departments that need precision-ground or precision-rolled stock ready to machine and heat treat. A2 material machines well in the annealed state before hardening and delivers stable dimensions through the air-hardening process, making it a reliable choice for close-tolerance tooling components in both light industrial and production environments.

Installation Notes

Machining and grinding of A2 tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate cutting fluids and tooling rated for tool steel. Heat treatment, including hardening and tempering, should follow established AISI A2 heat treat procedures and is typically performed by a qualified heat treater or tool room professional. Always wear appropriate personal protective equipment when cutting, grinding, or handling tool steel stock. Follow applicable shop safety codes and manufacturer heat treat guidelines for A2 material.
