Measuring 1.5 inches thick, 3 inches wide, and 18 inches long, this flat stock is cut to a size suited for fabricating punches, dies, gauges, and other tooling components that require dimensional stability through the hardening process. A2 tool steel is an air-hardening alloy grade known for its balance of wear resistance and toughness. This stock is supplied in an annealed condition, ready for machining prior to heat treatment. Machinists, tool-and-die makers, and industrial fabricators work with this material in shop environments.\u003c\/p\u003e\u003cp\u003eA2 air-hardening flat stock in this size range is commonly used in tool and die shops, mold-making facilities, and precision machine shops. The 1.5-inch thickness and 3-inch width provide substantial cross-section material for blanking dies, forming tools, retainer plates, and structural tooling components. The 18-inch length allows for single-piece or multiple-part blanking from one bar. The controlled tolerances on all faces make this stock suitable for applications where dimensional accuracy after machining is critical before hardening.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel per AISI material specification\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of +0.010 to 0.015 inches for consistent stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of +0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of +0.010 to 0.015 inches across all faces\u003c\/li\u003e\n\u003cli\u003eSingle-piece package quantity suitable for low-volume toolroom procurement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock for use in toolmaking, die fabrication, and precision machining applications where an air-hardening alloy grade is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA2 tool steel flat stock is machined by skilled tool-and-die makers or machinists using conventional milling, grinding, and drilling equipment. Heat treatment to final hardness should be performed by a qualified heat-treating facility following established procedures for A2 air-hardening steel. All rough machining should be completed before hardening. Grinding to final tolerance is typically performed after heat treatment to account for any dimensional movement during the hardening cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: +0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 23 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 57667\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542399484210,"sku":"57667","price":1292.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_f54e4c01-ff00-4e30-8171-1b9f8fcfe63c.jpg?v=1785899682","url":"https:\/\/voomisupply.com\/products\/starrett-57667-a2-tool-steel-flat-stock-1-5x3x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
