Starrett 54634 A2 Tool Steel Flat Stock 5/16x1-1/2x36in

Product Description

The STARRETT 54634 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need precision-ground material ready for heat treatment. It measures 5/16 inches thick, 1-1/2 inches wide, and 36 inches long, and ships at approximately 5.49 pounds. A2 tool steel offers good dimensional stability during air hardening and provides a solid balance of wear resistance and toughness, making it a standard choice for punches, dies, gauges, and cutting tools. The thickness and squareness tolerances are held to tight limits, reducing the amount of grinding required before fabrication.

This flat stock is suited for job shops, tool and die operations, and maintenance departments that machine custom tooling components from raw stock. It is appropriate for applications where air-hardening steel is specified to minimize distortion during the hardening cycle. The 36-inch length allows for multiple parts to be cut from a single bar, reducing material waste in short-run tooling production. No special handling equipment is required for receiving or staging this bar size.

Key Features

• AISI A2 air-hardening tool steel for minimal distortion during heat treatment
• Thickness tolerance of plus or minus 0.001 inches for consistent stock removal in machining
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus 0.25 inches
• Squareness held to 0.003 inches per inch on all edges
• 36-inch bar length accommodates multiple part blanks from a single piece

Compatibility

Designed as a general-purpose A2 tool steel flat bar for use in toolmaking, die making, and precision machining applications requiring air-hardening steel stock.

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate metalworking equipment. Follow the material supplier heat treatment guidelines for A2 steel when hardening, including proper austenitizing temperature and air-cool quench procedures. Wear appropriate personal protective equipment when sawing, grinding, or handling bar stock with sharp edges. Verify dimensional requirements against your print before machining to finished size.
