Starrett 54707 A2 Tool Steel Flat Stock 1x4x36 in

Product Description

The STARRETT 54707 is an A2 air-hardening tool steel flat stock bar measuring 1 inch thick, 4 inches wide, and 36 inches long. A2 tool steel is a versatile, oil-free air-hardening alloy known for its dimensional stability during heat treatment and its balance of toughness and wear resistance. This flat stock is precision-ground to tight tolerances, making it suitable for toolmakers, die makers, and machinists who need reliable starting material for punches, dies, gauges, and other precision tooling components. At 46.91 pounds, this is a full-length bar intended for professional shop use.

This flat stock is used in tool and die shops, manufacturing facilities, and machine shops where A2 tool steel is specified. Typical applications include the fabrication of cutting dies, forming dies, punches, and precision fixtures. The air-hardening characteristic of A2 minimizes distortion during hardening, which is critical when machining close-tolerance tooling. This bar is sold as a single piece and is suited for both prototyping and production tooling work.

Key Features

• AISI A2 air-hardening tool steel for minimal distortion during heat treatment
• Thickness tolerance of +/- 0.001 inches for precision fitment
• Width tolerance of +0.000 to +0.005 inches
• Length tolerance of +0.25 inches
• Square tolerance of +/- 0.001 inches; edge squareness 0.003 per inch
• Full 36-inch length provides maximum material for layout and cutting

Compatibility

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

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate equipment. Follow all shop safety protocols including eye protection, secure workholding, and proper coolant use when machining. Heat treatment of A2 tool steel should be carried out by personnel familiar with air-hardening procedures and applicable metallurgical specifications. Always verify finished dimensions after any grinding or stress-relief operations.
