It measures 0.125 inches thick, 8 inches wide, and 18 inches long, and ships in an annealed, pre-machined flat condition ready for layout, milling, or grinding before heat treatment. A2 tool steel offers a strong balance of wear resistance and dimensional stability during air hardening, making it a reliable choice for punches, dies, gauges, and cutting tools. This flat stock is sized for low-volume use, with a minimum order quantity of one piece.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for tool and die shops, machine shops, and maintenance departments requiring accurately sized A2 steel blanks. The 8-inch width and 18-inch length provide enough material for a range of tooling layouts without requiring additional sawing from bar stock. It is commonly worked by licensed machinists and tool and die makers who heat treat in-house or send out for professional hardening and tempering after final grinding.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for good wear resistance and minimal distortion during heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus 0.010 to 0.015 inches for consistent stock removal planning\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus 0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with no minimum order beyond one unit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock blank for use in general toolmaking, die making, and precision machining applications requiring air-hardening steel in flat form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of tool steel flat stock should be performed by qualified machinists using appropriate cutting fluids and tooling rated for hardened or semi-hardened steel. Heat treatment, including hardening and tempering, should follow AISI A2 guidelines and be performed by experienced personnel with proper furnace equipment. Always allow the workpiece to reach ambient temperature before final grinding to finished dimensions. Secure the workpiece firmly before any milling, sawing, or grinding operation to prevent movement and injury.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI Type A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 8 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 0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth Tolerance\u003c\/strong\u003e: plus 0.010 to 0.015 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 0.010 to 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 57556\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544626004274,"sku":"57556","price":482.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_121db3d3-a4c0-4283-830a-a39aad1b49d4.jpg?v=1785931922","url":"https:\/\/voomisupply.com\/products\/starrett-57556-a2-tool-steel-flat-stock-0-125x8x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
