Starrett 54611 A2 Tool Steel Flat Stock 3/16x1-1/4x18in

Product Description

The STARRETT 54611 is an A2 air-hardening tool steel flat stock bar intended for toolmakers, machinists, and die makers who require tight dimensional tolerances and consistent material properties. Produced to AISI A2 specifications, this flat stock measures 3/16 inches thick, 1-1/4 inches wide, and 18 inches long, and weighs 1.19 pounds. A2 tool steel is known for its good wear resistance and dimensional stability during heat treatment, making it a practical choice for punches, dies, gauges, and similar precision tooling applications.

This flat stock is suited for machine shops, tool rooms, and fabrication environments handling light to medium tooling work. The 18-inch length accommodates a wide range of blanking and machining operations without requiring initial resizing. Its air-hardening designation means it can be hardened in still or forced air, reducing distortion compared to oil-hardening grades. Trade professionals in precision machining and die work will find this bar ready for layout, milling, and grinding operations.

Installation Notes

Cutting, grinding, and heat treatment of tool steel should be performed by qualified machinists or toolmakers familiar with A2 material requirements. Always follow proper personal protective equipment protocols when cutting or grinding tool steel. Heat treatment, including hardening and tempering, should be performed according to the material specification and applicable shop procedures. Allow material to reach ambient temperature before taking final dimensional measurements.
