Starrett 57562 A2 Tool Steel Flat Stock 5/32x1-1/4x18in

Product Description

The STARRETT 57562 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who need a reliable, dimensionally consistent material blank for custom tooling, jigs, fixtures, and precision components. This flat stock measures 5/32 inches thick, 1-1/4 inches wide, and 18 inches long. The A2 tool steel grade provides good wear resistance and toughness after heat treatment, making it a common choice for cutting tools, punches, dies, and gauges. It ships in annealed condition, ready for machining before hardening.

This flat stock is suited for tool and die shops, maintenance machining operations, and fabrication environments where A2 tool steel is specified. The 18-inch length allows cutting to multiple shorter blanks in a single piece. Its compact cross-section at 5/32 inches by 1-1/4 inches makes it practical for producing small dies, blades, forming tools, and similar precision components where air-hardening steel is preferred over oil-hardening grades. Professional machinists and toolmakers are the primary users of this material in both prototype and production settings.

Installation Notes

Machining and heat treatment of A2 tool steel should be performed by qualified machinists or tool and die professionals. Standard shop safety practices apply when cutting, grinding, or machining tool steel stock. Heat treatment, including hardening and tempering, should follow the material manufacturer's guidelines for AISI A2 and be performed with appropriate equipment. Allow the workpiece to cool properly before handling after any thermal process.
