A2 tool steel offers excellent dimensional stability during heat treatment, moderate toughness, and good wear resistance, making it a go-to choice for toolmakers and machinists fabricating dies, punches, gauges, and similar precision tooling components. Weighing approximately 1.99 pounds, this flat stock ships in a single piece and is sized for direct use in tool and die shops, maintenance departments, and machine shops where close-tolerance blanks are needed without extensive pre-machining.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for applications in tool and die making, jig and fixture fabrication, and general precision machining environments. A2 air-hardening steel is commonly selected when distortion control after hardening is a priority. The 18-inch length and square cross-section profile make it practical for blanking, saw cutting, and milling into finished tooling components. It is appropriate for both job shop and production toolroom settings handling small-to-medium tooling work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel for reduced distortion during heat treat cycles\u003c\/li\u003e\n\u003cli\u003e0.625 inches thick by 0.625 inches wide square cross-section profile\u003c\/li\u003e\n\u003cli\u003e18 inches overall length with a length tolerance of +0.25 inches\u003c\/li\u003e\n\u003cli\u003eThickness, width, and square tolerances held to +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eSingle-piece package at approximately 1.99 pounds, ready for immediate use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock blank suitable for general tool and die, punch, gauge, and fixture fabrication applications where AISI A2 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate personal protective equipment.
