Starrett 54610 A2 Tool Steel Flat Stock 3/16x1x18 in

Product Description

The STARRETT 54610 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, die makers, and machinists who need precision-ground stock ready for heat treatment. Manufactured from AISI Type A2 tool steel, this flat bar measures 3/16 inches thick, 1 inch wide, and 18 inches long, and is held to tight dimensional tolerances including plus or minus 0.001 inches on thickness and plus or minus 0.001 inches on squareness. A2 tool steel offers good dimensional stability during air hardening, making it a reliable choice for punches, dies, gauges, and fixture components.

This flat stock is suited for job shops, tool and die operations, and maintenance departments that fabricate or repair cutting tools, jigs, and precision fixtures. The 18-inch length provides enough material for most small-to-medium tooling blanks without requiring resawing from larger bar stock. Because it arrives in the annealed condition, it can be machined, ground, and then air hardened to final hardness in a controlled atmosphere or salt bath furnace.

Key Features

• AISI Type A2 air-hardening tool steel for good dimensional stability during heat treat
• Thickness tolerance of plus or minus 0.001 inches for precise fit in tooling applications
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus 0.250 inches
• Squareness tolerance of plus or minus 0.001 inches
• Supplied in annealed condition, ready for machining and subsequent heat treatment

Compatibility

Designed as a standard precision flat stock blank for use in tool and die, fixture, punch, gauge, and general toolmaking applications requiring AISI A2 air-hardening tool steel.

Installation Notes

Machining and grinding of A2 tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate cutting tools rated for tool steel. Heat treatment, including hardening and tempering, requires a controlled atmosphere or salt bath furnace and should be performed by personnel familiar with AISI A2 specifications. Always follow shop safety protocols when handling tool steel bar stock, including proper guarding on grinders and saws. Consult the material data sheet for recommended hardening temperatures and tempering cycles before heat treating.
