Measuring 0.125 inches thick, 3.5 inches wide, and 36 inches long, this flat stock is manufactured to AISI Type A2 material specification. A2 tool steel is valued for its dimensional stability during heat treatment and its resistance to wear and deformation under load. The stock ships at approximately 5.06 pounds and is ready for machining prior to hardening. Licensed machinists, toolmakers, and metalworking shops are the primary users of this material.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating punches, dies, gauges, jigs, and fixtures where consistent cross-section and tight tolerances are required. A2 air-hardening steel minimizes distortion during the hardening cycle compared to oil-hardening grades, making it a preferred choice for flat tool components that must hold their geometry after heat treatment. It is appropriate for both prototype and production toolmaking environments in job shops and manufacturing facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type A2 air-hardening tool steel for reduced distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness of 0.125 inches with a tolerance of plus 0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eWidth of 3.5 inches with a tolerance of plus 0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eLength of 36 inches with a tolerance of plus 0.250 to 0.500 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.003 inches for consistent cross-section geometry\u003c\/li\u003e\n\u003cli\u003eShips at approximately 5.06 pounds per piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat stock suitable for general toolmaking, die-making, and precision machining applications requiring an air-hardening grade material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining should be performed prior to heat treatment. A2 tool steel is air-hardened and should be processed by a qualified heat treater following appropriate temperature and atmosphere controls for the grade. Always use appropriate personal protective equipment when cutting or grinding tool steel.
