Manufactured to AISI A2 specification, this flat stock measures 0.5 inches thick, 1.5 inches wide, and 36 inches long, with a shipping weight of 8.79 pounds. A2 tool steel is known for its dimensional stability during heat treatment and its ability to hold a sharp edge after hardening, making it a reliable choice for punches, dies, gauges, and cutting tools. Machinists and tool and die makers work with this material in both job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for applications requiring tight dimensional tolerances in the annealed condition prior to heat treating. The controlled tolerances on thickness, width, and squareness make it ready for layout and machining with minimal material removal needed to reach final dimensions. It is commonly used to fabricate blanking dies, form punches, trim tools, and fixture components where air-hardening steel is specified for reduced distortion during the hardening cycle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel — reduced distortion during heat treat compared to oil-hardening grades\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal calculations\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to plus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches; edge squareness held to 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e36-inch length provides full bar stock for multiple blanks 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 bar suitable for use in toolmaking, die making, and precision machining applications where A2 specification material is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA2 tool steel flat stock is machined and ground by tool and die makers or machinists prior to heat treatment. Follow established AISI A2 hardening procedures, including proper austenitizing and air-quench cooling, performed by a qualified heat treater.
