Starrett 54760 A2 Tool Steel Flat Stock 0.625x2x18 in

Product Description

The STARRETT 54760 is an A2 air-hardening tool steel flat stock bar used in toolmaking, die work, and precision machining applications. It measures 0.625 inches thick, 2 inches wide, and 18 inches long, and weighs 6.4 pounds. The stock is held to tight dimensional tolerances: plus or minus 0.001 inches on thickness and squareness, plus 0.000 to 0.005 inches on width, and plus 0.250 inches on length. A2 tool steel offers good toughness and wear resistance with minimal distortion during air-hardening heat treatment. Machinists, tool and die makers, and metalworking tradespeople work with this material when building or reconditioning tooling components.

This flat stock is suited for fabricating punches, dies, gauges, jigs, and fixtures where dimensional stability through heat treat is required. The air-hardening characteristic of AISI A2 tool steel makes it a practical choice for shops that need consistent results without oil or water quench. It arrives in an annealed condition ready for machining before hardening. Typical applications span both prototype tooling and production die work in job shops and manufacturing environments.

Installation Notes

Machining and heat treatment of tool steel should be performed by qualified toolmakers or machinists familiar with AISI A2 grade material. Rough machine the stock before hardening, leaving adequate finishing stock for post-heat-treat grinding. Follow the steel manufacturer's recommended austenitizing temperature and air-cool procedure for A2. Wear appropriate PPE when cutting, grinding, or handling tool steel bar stock.
