Starrett 57332 A2 Tool Steel Flat Stock 3/16x1-3/4x36in

Product Description

The STARRETT 57332 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. Measuring 0.1875 inches thick, 1.75 inches wide, and 36 inches long, this flat stock ships in a ground and precision-toleranced condition ready for layout or machining. A2 tool steel offers excellent dimensional stability during heat treatment, making it a reliable choice for punches, dies, and gauges. Licensed machinists, tool-and-die makers, and maintenance technicians working in fabrication or industrial settings are the typical end users. The bar weighs approximately 3.85 pounds.

This flat stock is suited for job shops, maintenance departments, and toolrooms requiring a consistent, machinable blank. The 36-inch length provides enough material for multiple tool blanks from a single piece. A2 air-hardening steel responds well to standard machining operations before heat treatment and holds its shape with minimal distortion when air-quenched. Applications include cutting tools, form dies, punches, jigs, and fixtures where moderate toughness and good wear resistance are needed.

Key Features

• AISI A2 air-hardening tool steel — minimal distortion during heat treat
• Thickness tolerance of plus or minus 0.001 inches for precise fit-up
• Width tolerance of plus 0.000 to plus 0.005 inches
• Length tolerance of plus 0.25 inches
• Squareness tolerance: edge, all 0.003 inches per inch
• Single-piece packaging with no minimum order beyond one unit

Compatibility

Designed as a standard A2 tool steel flat bar suitable for use in toolmaking, die-making, and general precision fabrication where AISI A2 air-hardening material is specified.

Installation Notes

Machining and heat treatment of tool steel should be performed by or under the supervision of a qualified tool-and-die maker or machinist. Always allow the material to reach room temperature before precision layout or machining. A2 steel is air-hardened, meaning it must be quenched in still air or with forced air after austenitizing — do not quench in oil or water. Follow applicable shop safety practices and relevant OSHA standards when cutting, grinding, or heat treating tool steel stock.
