A2 tool steel is an air-hardening, cold-work die steel known for its dimensional stability during heat treatment and good wear resistance. This flat stock ships in the annealed condition, ready for machining, grinding, and final heat treatment by the end user. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for precision tooling applications where tight dimensional control is required before hardening. Weighing 3.66 pounds per bar, it is sized for single-unit use in tool and die shops, maintenance departments, and machine shops.\u003c\/p\u003e\u003cp\u003eThis flat stock is used in fabrication of punches, dies, gauges, knives, and general tooling components. It is appropriate for both short-run production tooling and maintenance replacement parts in industrial and manufacturing environments. Machinists and tool makers typically machine this material to near-final dimensions while it is in the soft, annealed state before sending it out for or performing in-house air hardening. The 36-inch length allows for multiple parts to be cut from a single bar, reducing material waste on typical tooling projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for consistent dimensional stability during heat treat\u003c\/li\u003e\n\u003cli\u003eThickness held to plus or minus 0.001 inches for precision fitment before hardening\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches for controlled stock removal\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches ensures full usable length\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003eSingle 36-inch bar format suitable for cutting multiple tooling blanks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose A2 air-hardening tool steel flat bar for use in tool and die fabrication, punch and die sets, gauges, blades, and precision machine components requiring air-hardening cold-work steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding should be performed while the material is in the annealed condition prior to heat treatment. Heat treatment of A2 tool steel, including austenitizing, air hardening, and tempering, should be performed by qualified personnel following established metallurgical procedures for AISI A2. Use appropriate personal protective equipment and follow shop safety protocols when cutting, grinding, or machining tool steel. Consult applicable material data sheets for full heat treatment parameters before processing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Air-Hardening Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI Type A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\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\u003eSquareness\u003c\/strong\u003e: Edge: All 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.66 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: 54632\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541649064242,"sku":"54632","price":267.87,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_d6c4bed2-a796-4f0c-9f72-5273993d6aba.jpg?v=1785881112","url":"https:\/\/voomisupply.com\/products\/starrett-54632-a2-tool-steel-flat-stock-5-16x1x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
