It measures 0.0625 inches thick, 3 inches wide, and 36 inches long, and is manufactured to tight dimensional tolerances: plus or minus 0.001 inches on thickness, plus 0.000 to 0.005 inches on width, and plus 0.25 inches on length. Squareness is held to 0.003 inches per inch on all edges. A2 tool steel offers good wear resistance and dimensional stability through the hardening process, making it a reliable choice for blanks, fixtures, and cutting tool stock.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die operations, and maintenance toolrooms where precision ground stock in A2 tool steel is required. It ships in the annealed condition and can be machined, ground, and heat-treated to final hardness by the end user. The 36-inch length provides enough material for most bench-size tooling blanks, stripper plates, and flat die components without requiring additional cutting on delivery.\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 held to plus or minus 0.001 inches tolerance\u003c\/li\u003e\n\u003cli\u003eWidth tolerance held to plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eAnnealed condition — ready for machining and heat treatment\u003c\/li\u003e\n\u003cli\u003eSingle-piece quantity with no minimum order above one piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock blank suitable for general toolmaking, die-making, and fixture fabrication applications requiring air-hardening steel in ground flat form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of A2 tool steel flat stock should be performed by qualified tool and die makers or machinists familiar with tool steel handling. Heat treatment to final hardness requires controlled atmosphere or vacuum furnace equipment and should follow established A2 hardening and tempering procedures. Secure workpieces properly before any cutting or grinding operations. Always wear appropriate PPE when machining tool steel stock.\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: 0.0625 inches (1\/16 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: 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 on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.2 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: 57308\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540244791602,"sku":"57308","price":276.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_05af50e8-83c4-4e68-8adb-3f54e5d4ad0a.jpg?v=1785850063","url":"https:\/\/voomisupply.com\/products\/starrett-57308-a2-tool-steel-flat-stock-3x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
