Manufactured from AISI A2 tool steel, this flat stock measures 0.75 inches thick, 1.75 inches wide, and 18 inches long, with a weight of 6.72 pounds. A2 tool steel offers good dimensional stability during heat treatment and strong wear resistance after hardening, making it a reliable choice for punches, dies, gauges, and similar tooling components. Thickness, width, and square tolerances are held to +0.010 to 0.015 inches, with a length tolerance of +0.25 inches, ensuring consistent stock removal and predictable fit in precision setups.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die shops, and maintenance departments that fabricate or repair tooling in-house. The 18-inch length provides sufficient material for most small-to-medium tool blanks without requiring cut-down from longer bar stock. A2 grade is widely specified where through-hardening with minimal distortion is required, particularly in applications that demand a balance of toughness and wear resistance at moderate production volumes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good dimensional stability during heat treat\u003c\/li\u003e\n\u003cli\u003eThickness: 0.75 inches with +0.010 to 0.015 inch tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 1.75 inches with +0.010 to 0.015 inch tolerance\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with +0.25 inch tolerance\u003c\/li\u003e\n\u003cli\u003eSquare tolerance held to +0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eWeighs 6.72 pounds per piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose A2 tool steel flat stock blank suitable for fabricating punches, dies, gauges, and other precision tooling components requiring air-hardening tool steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by qualified tool and die makers or machinists familiar with high-carbon alloy steels. Always follow appropriate personal protective equipment practices when grinding, cutting, or machining tool steel. Heat treatment should be performed in a controlled atmosphere or vacuum furnace to minimize decarburization. Consult the material data sheet for recommended austenitizing and tempering parameters before processing.\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: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.75 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\u003eSquare 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\u003eWeight\u003c\/strong\u003e: 6.72 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: 57626\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541485846834,"sku":"57626","price":323.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_717d5fc1-5093-4ec0-9aba-ef09a45484ff.jpg?v=1785877530","url":"https:\/\/voomisupply.com\/products\/starrett-57626-a2-tool-steel-flat-stock-0-75x1-75x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
