A2 tool steel is a versatile cold-work die steel known for its good balance of wear resistance, toughness, and dimensional stability during heat treatment. Air-hardening minimizes distortion and cracking risk during the hardening cycle. The bar ships in the annealed condition, ready for machining, grinding, and final hardening by a tool and die maker, machinist, or industrial maintenance professional. At 11.72 pounds, the bar is sized for bench-scale tooling work.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for fabricating punches, dies, gauges, forming tools, and similar cold-work tooling in job shops, tool rooms, and maintenance departments. The tight tolerances on thickness and squareness make it appropriate for applications where close-tolerance blanks are required before final grinding. It is a standard bar format used in both one-off toolmaking and low-volume production tool fabrication.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for predictable heat treatment with minimal distortion\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for consistent blank dimensions\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to plus 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: all edges held to 0.003 inches per inch\u003c\/li\u003e\n\u003cli\u003eSquare tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 tool steel flat stock bar suitable for cold-work tooling, die making, punch fabrication, and gauge manufacture where AISI A2 air-hardening steel is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of A2 tool steel should be performed by qualified machinists or tool and die makers using appropriate cutting speeds and coolant for tool steel. Heat treatment should follow established AISI A2 austenitizing and air-quench procedures and is typically performed by a qualified heat treater. Always allow the bar to reach ambient temperature before precision measurement. Secure the workpiece properly before any cutting or grinding operation.\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 (AISI A2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1 inch\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 plus 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: 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.72 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: 54702\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540283457842,"sku":"54702","price":697.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_9cd12a9c-9ed9-4731-bc5e-002b9922774e.jpg?v=1785851201","url":"https:\/\/voomisupply.com\/products\/starrett-54702-a2-tool-steel-flat-stock-1x1x36-in","provider":"Voomi Supply","version":"1.0","type":"link"}
