Starrett 54664 A2 Tool Steel Flat Stock 0.5x2.5x36 in

Product Description

The STARRETT 54664 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die making, and precision machining applications. Ground to tight tolerances, this flat stock ships in a ready-to-use condition and is suitable for fabricating punches, dies, gages, and other tooling components that require dimensional accuracy before hardening. At 0.5 inches thick, 2.5 inches wide, and 36 inches long, it provides a solid starting blank for a range of tool room operations. The material weighs 14.66 pounds. Thickness and squareness tolerances of plus or minus 0.001 inches make it suitable for precision work where dimensional consistency is critical prior to heat treatment.

This flat stock is intended for use in tool rooms, job shops, and manufacturing environments where A2 air-hardening tool steel is specified. A2 is a commonly used cold-work tool steel that offers good toughness, moderate wear resistance, and minimal distortion during air-hardening heat treatment. It is typically used for blanking dies, forming tools, trim dies, and similar cold-work tooling applications. Machinists, tool and die makers, and metalworking professionals work with this material in both prototype and production tooling contexts.

Key Features

• AISI A2 air-hardening tool steel — good toughness with minimal distortion during hardening
• Thickness tolerance of plus or minus 0.001 inches for precision fitment
• Width tolerance of plus 0.000 to 0.005 inches
• Length tolerance of plus 0.25 inches
• Squareness tolerance of plus or minus 0.001 inches; edge squareness 0.003 per inch
• 36-inch length provides a full blank for multiple tooling cuts

Compatibility

Designed as a standard A2 air-hardening tool steel flat stock blank suitable for cold-work tooling applications where AISI A2 material is specified.

Installation Notes

Cutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or tool and die makers using appropriate metalworking equipment. Follow established heat treatment procedures and applicable shop safety protocols when hardening A2 steel. Ensure proper eye and hand protection when cutting or grinding. Consult material safety data and heat treatment guidelines from a qualified metallurgical source before processing.
