Starrett 57334 A2 Tool Steel Flat Stock 3/16x8x36 in

Product Description

The STARRETT 57334 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Measuring 3/16 inches thick, 8 inches wide, and 36 inches long, it provides a substantial, ready-to-machine blank for fabricating punches, dies, gauges, and cutting tools. A2 tool steel offers good dimensional stability during heat treatment and a balance of hardness and toughness that makes it a go-to material for general-purpose toolroom applications. Thickness tolerance is held to plus or minus 0.001 inches, and squareness is maintained at 0.003 inches per inch on all edges.

This flat stock is suited for professional toolrooms, machine shops, and maintenance departments in industrial, manufacturing, and fabrication environments. It is commonly used when a shop needs to machine a custom die component, form tool, or precision fixture plate from a known, consistent tool steel grade. The 36-inch length provides enough material for multiple smaller blanks, reducing the need for multiple orders. Machinists, tool-and-die makers, and metalworking professionals are the typical end users.

Key Features

• AISI A2 air-hardening tool steel for good stability and wear resistance after heat treatment
• Thickness held to plus or minus 0.001 inches for precise, predictable stock removal
• Width tolerance of plus 0.000 to plus 0.005 inches ensures controlled fitment in die sets
• Length tolerance of plus 0.25 inches provides full usable length on every piece
• Squareness maintained at 0.003 inches per inch on all edges for accurate layout and fixturing
• 36-inch length yields multiple blanks from a single piece, reducing scrap

Compatibility

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

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or tool-and-die makers following established shop safety procedures. Always use appropriate personal protective equipment when sawing or grinding. Heat treatment to full hardness requires proper atmosphere or salt-bath equipment to maintain dimensional tolerances; follow the material supplier recommendations for austenitizing and quench procedures. Allow the workpiece to reach ambient temperature before taking final measurements.
