Manufactured from AISI Type A2 tool steel, this flat bar measures 3\/16 inches thick, 1 inch wide, and 18 inches long, and is held to tight dimensional tolerances including plus or minus 0.001 inches on thickness and plus or minus 0.001 inches on squareness. A2 tool steel offers good dimensional stability during air hardening, making it a reliable choice for punches, dies, gauges, and fixture components.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for job shops, tool and die operations, and maintenance departments that fabricate or repair cutting tools, jigs, and precision fixtures. The 18-inch length provides enough material for most small-to-medium tooling blanks without requiring resawing from larger bar stock. Because it arrives in the annealed condition, it can be machined, ground, and then air hardened to final hardness in a controlled atmosphere or salt bath furnace.\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 treat\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precise fit in tooling applications\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.250 inches\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance of plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003eSupplied in annealed condition, ready for machining and subsequent heat treatment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard precision flat stock blank for use in tool and die, fixture, punch, gauge, and general toolmaking applications requiring AISI A2 air-hardening tool steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and grinding of A2 tool steel flat stock should be performed by qualified toolmakers or machinists using appropriate cutting tools rated for tool steel. Heat treatment, including hardening and tempering, requires a controlled atmosphere or salt bath furnace and should be performed by personnel familiar with AISI A2 specifications. Always follow shop safety protocols when handling tool steel bar stock, including proper guarding on grinders and saws. Consult the material data sheet for recommended hardening temperatures and tempering cycles before heat treating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Tool Steel, AISI Type A2 Air-Hardening\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3\/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: 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\u003eSquareness Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.95 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: 54610\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542140911922,"sku":"54610","price":108.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_6b4c1e33-8081-4dc4-aa58-5ac0eb54abd6.jpg?v=1785893393","url":"https:\/\/voomisupply.com\/products\/starrett-54610-a2-tool-steel-flat-stock-3-16x1x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
