Manufactured from AISI A2 tool steel, this flat stock measures 1\/16 inch thick, 1-1\/4 inches wide, and 36 inches long, weighing approximately 0.92 pounds. A2 tool steel offers good wear resistance, dimensional stability during heat treatment, and moderate toughness, making it a reliable choice for tooling components that require air-hardening with minimal distortion. Machinists, tool and die makers, and fabricators typically work with this material in a softened or annealed state before hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for light-gauge tooling applications in machine shops, tool rooms, and precision fabrication environments. Its 36-inch length provides enough material for multiple tooling blanks from a single piece. The 1\/16-inch thickness makes it appropriate for thin punches, blades, stripper plates, and similar components. The material ships in its pre-hardened soft state and is ready for machining, grinding, and subsequent heat treatment to desired hardness.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for minimal distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches; edge squareness 0.003 per inch\u003c\/li\u003e\n\u003cli\u003e0.92 pounds per 36-inch length for easy handling and inventory planning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose A2 tool steel flat stock suitable for tool and die, punch and die, jig and fixture, and precision machining applications where air-hardening tool steel stock is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding should be performed while the stock is in the annealed condition prior to heat treatment. Heat treatment of A2 tool steel should be performed by a qualified heat treater following AISI guidelines for austenitizing temperature and air-quench procedure. Always wear appropriate PPE when cutting, grinding, or handling tool steel stock. Deburr all edges before handling finished tooling components.\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\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1-1\/4 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\u003eEdge Squareness\u003c\/strong\u003e: 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.92 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: 57304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543149543730,"sku":"57304","price":153.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_a54af1c6-6452-4b9f-a0cd-5542b6d8e445.jpg?v=1785916466","url":"https:\/\/voomisupply.com\/products\/starrett-57304-a2-tool-steel-flat-stock-1-16x1-1-4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
