Starrett 54562 A2 Tool Steel Flat Stock 5/32x3x36 in

Product Description

The STARRETT 54562 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers working in precision tooling and fabrication environments. Measuring 5/32 inches thick, 3 inches wide, and 36 inches long, this flat stock is machined to tight tolerances, including a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.000 to 0.005 inches. The A2 tool steel material specification delivers good wear resistance and dimensional stability through the air-hardening process, making it well suited for dies, punches, gauges, and similar tooling applications. Weighing 5.49 pounds, this bar ships as a single piece.

This flat stock is used in machine shops, tool and die operations, and precision fabrication settings where consistent stock dimensions and tight tolerances are required before hardening. The 36-inch length provides sufficient stock for cutting multiple blanks or machining a full-length tool component. The A2 specification suits applications where air hardening is preferred over oil or water quench processes, reducing the risk of distortion during heat treatment. Typical end uses include forming dies, blanking dies, gauges, and precision wear components.

Key Features

• A2 air-hardening tool steel provides good toughness and wear resistance with minimal distortion during hardening
• Thickness tolerance of plus or minus 0.001 inches supports precision layout and machining without additional surface grinding
• Width tolerance of plus 0.000 to 0.005 inches ensures consistent stock width across the bar length
• Squareness specification of 0.003 inches per inch on all edges supports accurate setup and fixturing
• Length tolerance of plus 0.25 inches allows for full-length usable stock after facing cuts
• Single-piece packaging with no minimum order beyond one unit

Compatibility

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

Installation Notes

Cutting and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate metalworking equipment. Follow established shop safety practices when sawing, milling, or grinding this material. Heat treatment, including hardening and tempering of A2 steel, should be performed according to the material specification and applicable shop procedures by qualified personnel. Ensure all cutting tools and workholding are rated for tool steel machining before beginning operations.
