Measuring 0.125 inches thick, 2 inches wide, and 18 inches long, this flat stock is produced to AISI A2 material specification. A2 tool steel offers good dimensional stability during air hardening, moderate toughness, and strong wear resistance, making it a reliable choice for punches, dies, gauges, and cutting tools. The piece ships in a single-piece package at a weight of 1.28 pounds, ready for machining and subsequent heat treatment.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for machine shops, tool and die operations, and maintenance departments that fabricate or repair tooling in-house. It is appropriate for applications where controlled air hardening is preferred over oil or water quench to minimize distortion. The 18-inch length provides enough material for most short-run tooling blanks without requiring further resizing in many standard applications. A2 flat stock of this size is commonly used for punch blanks, flat dies, form blocks, and precision wear pads in both production and prototype environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for low-distortion heat treatment\u003c\/li\u003e\n\u003cli\u003eThickness: 0.125 inches with a tolerance of +0.010 to +0.015 inches\u003c\/li\u003e\n\u003cli\u003eWidth: 2 inches with a tolerance of +0.010 to +0.015 inches\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with a tolerance of +0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquare tolerance: +0.010 to +0.015 inches for consistent flatness and squareness\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with a shipping weight of 1.28 pounds\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 use in standard tool and die, punch, and precision machining applications where AISI A2 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel flat stock should be performed by qualified toolmakers or machinists familiar with tool steel handling. Follow the material manufacturer's recommended preheat, hardening, and tempering cycles for AISI A2 steel to achieve the desired hardness and minimize distortion. Use appropriate cutting fluids and carbide tooling when machining in the annealed state. Wear proper personal protective equipment when grinding or machining tool steel stock.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel, AISI 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: 2 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\u003eLength Tolerance\u003c\/strong\u003e: +0.25 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\u003eWeight\u003c\/strong\u003e: 1.28 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: 57548\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539499254066,"sku":"57548","price":131.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_55abec2f-bfa4-4429-a6a3-9411e14f12d3.jpg?v=1785841852","url":"https:\/\/voomisupply.com\/products\/starrett-57548-a2-tool-steel-flat-stock-0-125x2x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
