Measuring 1.25 inches thick, 4 inches wide, and 12 inches long, this bar ships as a single piece and weighs approximately 18.44 pounds. The 4140 designation indicates a chromium-molybdenum alloy known for high tensile strength, good fatigue resistance, and solid machinability in its pre-hardened state. Because it arrives already hardened, no additional heat treatment is required before use in most fabrication or repair scenarios.\u003c\/p\u003e\n\u003cp\u003eThis flat bar is suited for machine shops, maintenance departments, and industrial fabricators working in metalworking, tooling, and general mechanical applications. The pre-hardened condition makes it a practical choice for die blocks, shafts, fixtures, and structural components that require consistent hardness throughout the cross section. It is appropriate for both light manufacturing environments and heavy industrial settings where 4140 alloy steel is a specified material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4140 chromium-molybdenum alloy steel for high strength and fatigue resistance\u003c\/li\u003e\n  \u003cli\u003ePre-hardened condition eliminates need for additional heat treatment in most applications\u003c\/li\u003e\n  \u003cli\u003eFlat bar form factor at 1.25 inches thick by 4 inches wide by 12 inches long\u003c\/li\u003e\n  \u003cli\u003eSingle-piece packaging with a minimum order quantity of 1\u003c\/li\u003e\n  \u003cli\u003eWeight of 18.44 pounds supports accurate freight and handling planning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use material for applications specifying 4140 pre-hardened alloy steel flat bar stock in the stated dimensions.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eCutting, drilling, or machining 4140 pre-hardened steel requires carbide or high-speed steel tooling rated for hardened alloy materials. Use appropriate personal protective equipment including eye protection and gloves when cutting or grinding. Consult applicable shop safety standards before machining. Verify dimensional tolerances against your application drawing before cutting to final size, as machined surfaces cannot be restored once removed.\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: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 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: 18.44 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: DA1.25X04.0X12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51722230071602,"sku":"DA1.25X04.0X12","price":135.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdf0224c31800520f930bb4f3ef507e3_bc11a936-92a5-4de0-9b24-6015361ac5ed.jpg?v=1788587823","url":"https:\/\/voomisupply.com\/products\/value-collection-da1-25x04-0x12-4140-steel-flat-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
