It measures 0.5 inches thick, 1.75 inches wide, and 36 inches long, and ships at approximately 10.26 pounds. A2 tool steel offers good wear resistance, moderate toughness, and predictable dimensional stability through the air-hardening process, making it a reliable choice for shops that need consistent, close-tolerance stock. Thickness tolerance is held to plus or minus 0.001 inches, and squareness is maintained to 0.003 inches per inch on all edges.\u003c\/p\u003e\u003cp\u003eThis flat stock is suited for tool rooms, machine shops, and production environments requiring tight-tolerance raw material. It is appropriate for fabricating punches, dies, cutting tools, wear plates, and precision fixtures. The air-hardening characteristic of A2 allows for reduced distortion during heat treatment compared to oil-hardening grades, which is useful when final dimensions must be held close after hardening. Machinists, tool and die makers, and precision fabricators typically work with this material in both pre-hardened and annealed conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAISI A2 air-hardening tool steel for reduced distortion during heat treatment\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\u003c\/li\u003e\n\u003cli\u003eLength tolerance of plus 0.25 inches\u003c\/li\u003e\n\u003cli\u003eSquareness held to 0.003 inches per inch on all edges\u003c\/li\u003e\n\u003cli\u003e36-inch length provides standard working stock for most tool room applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard AISI A2 air-hardening tool steel flat bar suitable for general tool room and precision machining applications requiring close-tolerance raw stock.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, grinding, and machining of tool steel should be performed with appropriate tooling rated for hardened or semi-hardened steel stock. Follow standard shop safety practices including eye and hand protection when sawing or grinding. Heat treatment should be performed by qualified personnel following established A2 austenitizing and air-quench procedures. Consult applicable shop standards and material data sheets before hardening to verify final dimensional allowances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: A2 Tool Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: AISI Type 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: 1.75 inches\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: 0.003 inches per inch, all edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.26 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: 57350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539487490354,"sku":"57350","price":551.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd4885fbdd426ecb0fa6c3cc24fba2db_e7ff0c21-54d9-4677-9584-0dba7acb566e.jpg?v=1785841460","url":"https:\/\/voomisupply.com\/products\/starrett-57350-a2-tool-steel-air-hardening-flat-stock","provider":"Voomi Supply","version":"1.0","type":"link"}
