Starrett 54794 A2 Tool Steel Flat Stock 1x5x18 in

Product Description

The STARRETT 54794 is an A2 air-hardening tool steel flat stock bar measuring 1 inch thick, 5 inches wide, and 18 inches long. A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treat and its balance of toughness and wear resistance. This flat stock is ground to tight tolerances — plus or minus 0.001 inch on thickness and squareness — making it suitable for toolmakers, die makers, and machinists who need a reliable starting blank for punches, dies, gauges, and precision tooling components.

A2 flat stock in this size range is commonly used in tool and die shops, precision machining operations, and maintenance departments where custom tooling is fabricated in-house. The 1 inch by 5 inch cross section provides substantial material for milling, grinding, or EDM work into finished tooling. The 18-inch length allows multiple blanks to be cut from a single piece. This stock is appropriate for applications where moderate impact resistance and good wear life after hardening are required, such as forming dies, trim dies, and fixture components.

Key Features

• AISI A2 air-hardening tool steel for dimensional stability during heat treatment
• Ground flat stock with plus or minus 0.001 inch thickness tolerance
• Plus or minus 0.001 inch squareness tolerance for accurate layout and machining
• Width tolerance of plus 0.000 to 0.005 inch
• Length tolerance of plus 0.250 inch to allow for cutoff
• Ready-to-machine starting blank for dies, punches, gauges, and precision tooling

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock blank suitable for general tool and die fabrication, fixture building, and precision machining applications requiring AISI A2 material specification.

Installation Notes

A2 tool steel flat stock is worked by qualified toolmakers and machinists using conventional milling, grinding, and EDM equipment. Material should be stress-relieved or annealed before machining if required by the application. Heat treatment to harden A2 steel should be performed by a qualified heat treater following established procedures for AISI A2 tool steel. Always follow proper machine shop safety practices and wear appropriate PPE when cutting or grinding tool steel stock.
