Starrett 54755 A2 Tool Steel Flat Stock 0.5x6x18 in

Product Description

The STARRETT 54755 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Measuring 0.5 inches thick, 6 inches wide, and 18 inches long, this flat stock is supplied to close 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 offers good wear resistance and dimensional stability through the air-hardening heat treatment process, making it a preferred choice for production tooling and precision fixtures.

This flat stock is suited for machine shops, tool and die shops, and maintenance departments requiring a reliable A2 tool steel blank. Typical uses include cutting tools, punches, dies, gauges, and precision fixtures where consistent stock dimensions and tight tolerances are essential. The 0.5 inch by 6 inch by 18 inch format provides sufficient material for machining multiple smaller components or a single larger tool blank. It is intended for use by machinists, tool and die makers, and industrial maintenance professionals.

Key Features

• A2 air-hardening tool steel for good wear resistance and dimensional stability after heat treatment
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal calculations
• Width tolerance of plus 0.000 to 0.005 inches for predictable fit in precision applications
• Squareness tolerance of plus or minus 0.001 inches supports accurate layout and machining setups
• Length tolerance of plus 0.250 inches provides extra stock for facing and squaring operations
• AISI A2 material specification for broad compatibility with standard heat treatment processes

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock blank suitable for general toolmaking, die making, and precision machining applications where AISI A2 material specification is required.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified machinists or tool and die makers familiar with high-carbon, high-chromium tool steels. Use appropriate cutting fluids and tooling rated for tool steel stock. Heat treatment including hardening and tempering should follow established metallurgical procedures for AISI A2 and must be performed with proper safety equipment and ventilation. Always secure the workpiece properly before any cutting or grinding operation.
