Measuring 5\/32 inches thick, 3\/4 inches wide, and 18 inches long, this flat stock is manufactured to tight dimensional tolerances, including a thickness tolerance of plus or minus 0.001 inches and a width tolerance of plus 0.000 to 0.005 inches. A2 tool steel offers excellent dimensional stability during heat treatment, making it a dependable choice when consistent hardness and minimal distortion are required after hardening. Machinists, tool and die makers, and industrial maintenance professionals work with this material to fabricate punches, dies, gauges, and similar precision tooling components.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for shop and production environments where A2 air-hardening steel is specified. It is commonly used in the fabrication of cutting tools, form dies, and jigs where controlled heat treat response and good wear resistance are needed. The 18-inch length is practical for benchtop machining or as feedstock for further cutting to size. The 5\/32 by 3\/4 inch cross-section suits thin-profile tooling and close-clearance die components. Both job shops and in-house maintenance toolrooms stock A2 flat bar in this size range as a standard working material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel composition for stable, low-distortion hardening\u003c\/li\u003e\n\u003cli\u003eThickness: 5\/32 inches with plus or minus 0.001 inch tolerance\u003c\/li\u003e\n\u003cli\u003eWidth: 3\/4 inches with plus 0.000 to 0.005 inch tolerance\u003c\/li\u003e\n\u003cli\u003eLength: 18 inches with plus 0.250 inch length tolerance\u003c\/li\u003e\n\u003cli\u003eSquare tolerance held to plus or minus 0.001 inches for precise fitment\u003c\/li\u003e\n\u003cli\u003eReady-to-machine flat stock format — no additional forming required before use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock for use in any application requiring AISI A2 material specification, including tool and die fabrication, punch and die sets, and precision gauging components.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of tool steel should be performed by qualified toolmakers or machinists familiar with AISI A2 material handling procedures. Always follow established shop safety practices when cutting, grinding, or hardening tool steel, including appropriate PPE for grinding and heat treat operations. Hardening and tempering of A2 steel requires controlled furnace equipment — do not attempt open-flame hardening. Consult the material data sheet for recommended heat treat cycles 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: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/4 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 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 0.250 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\u003eWeight\u003c\/strong\u003e: 0.61 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: 57514\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542458335538,"sku":"57514","price":87.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_53b255da-7a1a-4ca9-9e12-0f63518c6830.jpg?v=1785900999","url":"https:\/\/voomisupply.com\/products\/starrett-57514-a2-tool-steel-flat-stock-5-32x3-4x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
