A2 tool steel is a cold-work alloy known for its balanced combination of wear resistance, toughness, and dimensional stability during heat treatment. The air-hardening characteristic minimizes distortion during the hardening process, making this material well suited for applications requiring tight finished tolerances. This flat stock is intended for use by machinists, toolmakers, and die makers who fabricate cutting tools, punches, dies, jigs, and fixtures.\u003c\/p\u003e\u003cp\u003eThis flat stock is a standard choice in tool and die shops, production machining environments, and maintenance departments requiring reliable cold-work tool steel. The 18-inch length and 3-inch width provide sufficient material for a broad range of tooling blanks and custom fabrications. Thickness tolerance is held to plus or minus 0.001 inches, width tolerance runs plus 0.000 to 0.005 inches, length tolerance is plus 0.250 inches, and squareness tolerance is plus or minus 0.001 inches. These tolerances support precise layout and minimal cleanup stock on critical surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eA2 air-hardening tool steel construction minimizes distortion during hardening cycles\u003c\/li\u003e\n\u003cli\u003eThickness tolerance of plus or minus 0.001 inches for precision fitment\u003c\/li\u003e\n\u003cli\u003eWidth tolerance of plus 0.000 to 0.005 inches supports tight layout work\u003c\/li\u003e\n\u003cli\u003eSquareness tolerance held to plus or minus 0.001 inches\u003c\/li\u003e\n\u003cli\u003e18-inch length with plus 0.250-inch length tolerance provides full usable stock\u003c\/li\u003e\n\u003cli\u003eAISI A2 material specification suitable for punches, dies, jigs, and fixture components\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-profile A2 tool steel flat stock for use in tool and die fabrication, punch and die sets, and precision fixture construction requiring an air-hardening cold-work steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel flat stock should be performed by qualified machinists or toolmakers using appropriate coolant and tooling rated for hardened or semi-hardened steel. Material should be annealed before machining where full hardness is not required, and hardened to final specification following AISI A2 heat treatment guidelines before finish grinding. Always wear appropriate PPE when cutting or grinding tool steel. Follow applicable shop safety codes when operating machine tools.\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: 0.5 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 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: 7.56 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: 54750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542442574130,"sku":"54750","price":455.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_9636313c-0169-4310-b7e1-104fef8e3286.jpg?v=1785900664","url":"https:\/\/voomisupply.com\/products\/starrett-54750-a2-tool-steel-flat-stock-0-5x3x18-in","provider":"Voomi Supply","version":"1.0","type":"link"}
