It measures 1.25 inches thick, 2 inches wide, and 36 inches long, and weighs 27.55 pounds. The 4140 alloy designation indicates a chromium-molybdenum steel that delivers high tensile strength, good toughness, and solid wear resistance in the pre-hardened condition. Machinists, tool and die makers, and fabricators use this bar stock as raw material for shafts, dies, fixtures, and structural components that require a balance of hardness and machinability without requiring additional heat treatment before use.\u003c\/p\u003e\u003cp\u003eThis flat bar is suited for industrial and commercial fabrication environments where 4140 pre-hardened stock is specified. Common applications include manufacturing custom tooling, jigs, fixtures, wear plates, and machine components. The pre-hardened condition makes it ready for machining to final dimensions without a separate hardening step, which reduces lead time in production settings. Metal fabrication shops, maintenance departments, and toolrooms typically keep this size on hand for on-demand part production.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4140 chromium-molybdenum alloy steel provides high tensile strength and solid impact toughness\u003c\/li\u003e\n\u003cli\u003ePre-hardened condition eliminates the need for additional heat treatment before machining\u003c\/li\u003e\n\u003cli\u003eFlat bar profile at 1.25 inches thick by 2 inches wide suits tooling and fixture stock applications\u003c\/li\u003e\n\u003cli\u003e36-inch length allows multiple parts to be cut from a single bar\u003c\/li\u003e\n\u003cli\u003eConsistent cross-section supports precise layout and machining to tight tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose 4140 pre-hardened steel flat bar suitable for tooling, die, fixture, and structural machining applications where 4140 alloy bar stock is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting and machining of pre-hardened 4140 steel should be performed by qualified machinists or fabricators using appropriate carbide tooling. Secure the bar firmly in a vise or fixture before sawing or milling to prevent movement. Grinding or machining operations may produce metal chips and heat — use proper eye protection, gloves, and coolant where applicable. Verify all dimensions against engineering drawings before cutting, as cut material cannot be returned to original length.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 4140 Steel\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: 1.25 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: 36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 27.55 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 30263600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: DA1.25X02.0X36\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51696798564658,"sku":"DA1.25X02.0X36","price":215.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26f9b8db5a29db76d884854a979dc2d4_8f5e50aa-0aeb-4e0f-9dd7-2ccb69edbfd9.jpg?v=1788346357","url":"https:\/\/voomisupply.com\/products\/value-collection-da1-25x02-0x36-4140-steel-flat-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
