Manufactured to AISI A2 specification, this flat stock measures 0.375 inches thick, 3 inches wide, and 36 inches long, with a thickness tolerance of +\/- 0.001 inches and a squareness tolerance of +\/- 0.001 inches. A2 tool steel offers excellent wear resistance and dimensional stability during heat treatment, making it a preferred material for punches, dies, cutting tools, and gauges. Licensed machinists, tool-and-die makers, and industrial fabricators are the primary users of this stock.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool rooms, and manufacturing environments requiring close-tolerance raw material for fabricating precision components. The 36-inch length provides practical stock for multiple part layouts, and the 3-inch width accommodates a range of die and punch profiles. Width tolerance is held to + 0.000 to 0.005 inches, and length tolerance is + 0.25 inches, consistent with precision ground flat stock standards. Edge squareness is maintained at 0.003 inches per inch across all edges.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for stable, predictable heat treatment response\u003c\/li\u003e\n\u003cli\u003eThickness held to +\/- 0.001 inches for precise fit in tooling assemblies\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of +\/- 0.001 inches across all faces\u003c\/li\u003e\n\u003cli\u003eEdge squareness: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of + 0.000 to 0.005 inches for close-fit applications\u003c\/li\u003e\n\u003cli\u003e36-inch length with + 0.25 inch length tolerance for flexible stock utilization\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose precision ground flat stock for tool-and-die, punch, gauge, and cutting tool fabrication in shop and manufacturing environments requiring AISI A2 air-hardening tool steel.\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 tool-and-die makers using appropriate coolant and tooling rated for hardened or pre-hardened steel. Heat treatment should follow AISI A2 guidelines and be performed in a controlled atmosphere furnace to minimize decarburization. Always use appropriate PPE when cutting or grinding tool steel.
