Cut to 18 inches in length, 1-1\/2 inches wide, and 3\/32 inches thick, the bar ships in a ready-to-machine condition. Thickness and squareness tolerances are held to plus or minus 0.001 inches, and width tolerance is held to plus 0.000 to 0.005 inches, making this stock suitable for close-tolerance tool builds without additional surface grinding in most applications.\u003c\/p\u003e\u003cp\u003eA2 tool steel is a general-purpose air-hardening grade widely used in toolrooms and job shops for short-run punches, blanking dies, trim dies, gauges, and fixture components. Because it air-hardens, distortion during heat treatment is reduced compared to oil-hardening grades, which makes A2 a practical choice when a machined blank needs to hold dimensional stability through the hardening cycle. This flat stock format suits applications where bar stock would require significant material removal before roughing operations begin.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for reduced heat-treat distortion\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close-tolerance toolroom work\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003eFlat stock profile minimizes rough-machining stock removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose tool steel flat stock blank suitable for toolroom fabrication of punches, dies, gauges, and fixture components requiring A2 air-hardening material.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by a qualified toolmaker or machinist familiar with AISI A2 specifications. Always follow established shop safety practices when cutting, grinding, or handling tool steel bar stock. Heat treatment, including hardening and tempering cycles, should conform to the material manufacturer's guidelines for A2 grade steel. Use appropriate personal protective equipment during all machining and heat-treat operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Air-Hardening Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/2 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: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.73 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31231200\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: 57502\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542505685298,"sku":"57502","price":120.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_a2963323-f95e-41a3-889c-d60fa750ca8e.jpg?v=1785902283","url":"https:\/\/voomisupply.com\/products\/starrett-57502-a2-tool-steel-flat-stock-3-32x1-1-2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
