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 is commonly stocked by tool and die shops, maintenance departments, and machine shops for fabricating dies, punches, gauges, and cutting tools. Tight machined tolerances are held throughout, making it ready for layout and machining straight from stock without additional surface conditioning.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for tool and die applications in general metalworking and industrial manufacturing environments. Its air-hardening characteristic reduces distortion during the hardening cycle compared to oil or water-hardening grades, making it a preferred choice where dimensional accuracy after heat treat is critical. Licensed machinists, tool and die makers, and industrial maintenance technicians typically source and machine this material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel composition for reduced heat-treat distortion\u003c\/li\u003e\n\u003cli\u003ePre-cut flat stock at 1.25 inches thick, 3 inches wide, 18 inches long  -  ready for immediate layout and machining\u003c\/li\u003e\n\u003cli\u003eThickness tolerance held to plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to minus 0.005 inches for close-tolerance die work\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus or minus 0.062 inches\u003c\/li\u003e\n\u003cli\u003eSquareness: 0.003 inches per inch of thickness on edges, 0.004 inches per inch of thickness on ends\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard A2 air-hardening tool steel flat stock suitable for tool and die fabrication, punches, gauges, and similar cold-work tooling applications where AISI A2 material specification is required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMachining and heat treatment of A2 tool steel should be performed by qualified tool and die makers or machinists familiar with cold-work die steels. Follow the material supplier's recommended austenitizing, soaking, and air-cool hardening procedures  -  do not quench in oil or water, as this grade is designed for air hardening only. Grinding operations after hardening should use appropriate wheel specifications to avoid surface burning or micro-cracking. Always wear appropriate personal protective equipment when cutting, grinding, or handling tool steel stock.\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: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 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 minus 0.005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Tolerance\u003c\/strong\u003e: plus or minus 0.062 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareness\u003c\/strong\u003e: 0.003 inches per inch of thickness (edges), 0.004 inches per inch of thickness (ends)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 19.34 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: DRILL ROD TOOL STEELS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 85998599\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DRILL ROD \u0026 TOOL STEELS","offers":[{"title":"Default Title","offer_id":51984758997298,"sku":"85998599","price":475.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0bd010a1cae711f9686084786dbdb869_d32e7001-0771-4acd-8430-b3622b8ed26a.jpg?v=1789985003","url":"https:\/\/voomisupply.com\/products\/drill-rod-tool-steels-85998599-a2-tool-steel-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
