Measuring 0.125 inches thick, 4 inches wide, and 36 inches long, it is ground to close tolerances on all faces. A2 tool steel offers good wear resistance and dimensional stability through the air-hardening process, making it a reliable choice for punches, dies, gauges, and similar toolroom components. At 5.86 pounds per piece, it is a full-length bar ready for layout and machining. Licensed machinists, tool and die makers, and industrial maintenance technicians work with this material regularly.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, maintenance departments, and toolrooms requiring precision-ground stock with tight dimensional control. The 36-inch length provides enough material for a range of part layouts without excessive waste. The 4-inch width accommodates larger die sections, fixture plates, and wear plates. A2 material is commonly selected when a good balance of toughness and wear resistance is needed and when distortion during heat treatment must be minimized.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel per AISI specification — minimal distortion during heat treat\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\u003eSquare tolerance of plus or minus 0.001 inches with edge squareness of 0.003 per inch\u003c\/li\u003e\n\u003cli\u003eGround flat stock format — suitable for immediate layout and machining\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat stock for use in general toolroom, die-making, and precision fabrication applications requiring ground flat bar stock.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of tool steel flat stock should be performed with tooling rated for hardened or semi-hard ferrous materials. Heat treatment should be carried out by a qualified heat treater following AISI A2 recommended austenitizing and air-quench procedures. Deburr all cut edges before handling or layout work. Follow applicable shop safety practices when sawing, grinding, or milling tool steel.\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 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: 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: 5.86 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: 54553\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539354845490,"sku":"54553","price":400.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_43453548-7e2c-4a38-a619-83dccb5267bb.jpg?v=1785838654","url":"https:\/\/voomisupply.com\/products\/starrett-54553-a2-tool-steel-flat-stock-1-8x4x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
