Manufactured from AISI Type A2 tool steel, this flat stock arrives in the annealed condition, ready for machining and subsequent heat treatment. It measures 0.125 inches thick, 1.5 inches wide, and 18 inches long, with a shipping weight of 0.96 pounds. The A2 grade offers good dimensional stability during air hardening, making it a reliable choice for punches, dies, gauges, and similar precision tooling components where tight tolerances are required after hardening.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die operations, and maintenance machining environments where small-quantity material cuts are needed. The 18-inch length makes it practical for producing multiple small tool blanks from a single piece. Machinists, tool and die makers, and precision metalworking professionals typically work with this material when fabricating custom cutting tools, jigs, fixtures, or wear components that will be heat treated to final hardness on-site or by a commercial heat treater.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI Type A2 air-hardening tool steel for good dimensional stability during 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: 1.5 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 of +0.010 to 0.015 inches for consistent right-angle geometry\u003c\/li\u003e\n\u003cli\u003eSold individually, with a minimum order quantity of 1 piece\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose A2 tool steel flat bar for use in any toolmaking, die making, or precision machining application requiring AISI A2 air-hardening material in a 0.125 x 1.5 x 18 inch blank size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA2 tool steel flat stock is worked by qualified machinists and tool and die makers using conventional milling, grinding, and drilling equipment. Material should be machined in the annealed condition before any heat treatment cycle. Heat treating operations, including hardening and tempering, should be performed by qualified personnel following established metallurgical practices for AISI A2 tool steel. Handle cut edges with care, as ground and machined surfaces can be sharp.\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: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.5 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: 0.96 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 57546\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541948530994,"sku":"57546","price":108.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_52fefa12-dd74-4c22-8a37-a22ba7284582.jpg?v=1785888285","url":"https:\/\/voomisupply.com\/products\/starrett-57546-a2-tool-steel-flat-stock-0-125x1-5x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
