The pre-hardened state eliminates the need for additional heat treatment before use in most applications. This bar is commonly worked by machinists, toolmakers, and metalworking shops that require a reliable, consistent steel stock for precision components.\u003c\/p\u003e\n\u003cp\u003eThis bar is suited for machining fixtures, jigs, tooling plates, dies, shafts, and structural machine components where a higher-strength alloy steel is required. At 12 inches in length, it is well sized for short-run prototype work or replacement part fabrication. Industrial maintenance shops, job shops, and production facilities regularly stock 4140 pre-hardened bar for on-demand machining of wear parts and mechanical components. The square cross-section simplifies setup on mills and lathes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4140 chromium-molybdenum alloy steel for high strength and toughness\u003c\/li\u003e\n  \u003cli\u003ePre-hardened condition ready for machining without additional heat treatment\u003c\/li\u003e\n  \u003cli\u003eSquare cross-section at 2 inches x 2 inches simplifies fixturing and setup\u003c\/li\u003e\n  \u003cli\u003e12-inch length suitable for prototype and short-run component fabrication\u003c\/li\u003e\n  \u003cli\u003e14.5-pound bar weight indicates dense, solid stock with no voids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose alloy steel bar stock for use in machining, toolmaking, and industrial fabrication applications requiring 4140 pre-hardened material.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting and machining of 4140 pre-hardened steel requires carbide tooling and appropriate cutting speeds to preserve tool life and surface finish. Secure the workpiece firmly in a vise or fixture before machining operations begin. Welding pre-hardened 4140 requires preheat and post-weld heat treatment procedures per applicable welding codes to avoid cracking. Always use appropriate PPE including eye protection and gloves when cutting or grinding steel bar stock.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Specification\u003c\/strong\u003e: 4140\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondition\u003c\/strong\u003e: Pre-Hardened\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 14.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 30263600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: DA2.0X02.0X12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721756934450,"sku":"DA2.0X02.0X12","price":112.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdf0224c31800520f930bb4f3ef507e3_9ab1ac71-0ec3-4b98-a840-0ccd7a64a4f0.jpg?v=1788580371","url":"https:\/\/voomisupply.com\/products\/value-collection-da2-0x02-0x12-4140-steel-bar-2x2x12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
