Measuring 3\/16 inches thick, 2 inches wide, and 36 inches long, this flat stock is ground to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.000 to 0.005 inches. The length tolerance is plus 0.25 inches. A2 tool steel offers good wear resistance, dimensional stability during heat treatment, and moderate toughness, making it a common choice for cold-work tooling. This material is typically cut, machined, and heat treated by tool and die makers or precision machinists.\u003c\/p\u003e\u003cp\u003eThis flat stock suits shop environments where ground, close-tolerance tool steel stock is required for fabricating blanks, fixtures, gauges, or cutting tools. The A2 air-hardening designation means it reaches full hardness through still-air quench, reducing distortion risk during heat treat compared to oil-hardening grades. It is appropriate for both one-off toolroom applications and short-run production of tooling components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel for reduced distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for close-fit tooling applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eGround flat stock format ready for layout, machining, or heat treating\u003c\/li\u003e\n\u003cli\u003e36-inch length provides full bar stock for cutting multiple blanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock suitable for cold-work die and tooling fabrication applications requiring ground, close-tolerance steel bar in 3\/16 inches by 2 inches cross-section.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed with tooling rated for hardened or semi-hardened steel; stock is typically supplied in the annealed condition and should be handled accordingly. Heat treatment to working hardness requires a controlled atmosphere or appropriate protective measures to prevent decarburization and should be performed by qualified personnel following established procedures for AISI A2 tool steel. Proper eye protection and secure workholding are required during sawing, grinding, or milling operations.\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: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 36 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 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch, all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.39 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: 54570\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541608792370,"sku":"54570","price":306.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_0c149280-7e0e-4034-b762-d17a9958e61e.jpg?v=1785880444","url":"https:\/\/voomisupply.com\/products\/starrett-54570-a2-tool-steel-flat-stock-3-16x2x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
