Measuring 0.5 inches thick, 4 inches wide, and 36 inches long, this bar ships as a single piece and weighs approximately 22.54 pounds. The 4140 designation indicates a chromium-molybdenum alloy steel known for its high tensile strength, toughness, and wear resistance in the pre-hardened state. It is well-suited for shops and trades requiring a reliable, dimensionally consistent steel stock that can be cut, drilled, or milled to spec.\u003c\/p\u003e\u003cp\u003eThis flat bar is commonly used in industrial maintenance, custom fabrication, jig and fixture building, die work, and structural repair applications. Its pre-hardened condition makes it a practical choice when working with components that require moderate to high strength without the added step of through-hardening after machining. It is appropriate for both shop floor fabrication environments and field repair scenarios where a precision-ground or saw-cut steel flat bar is needed to spec.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4140 chromium-molybdenum alloy steel construction for high strength and toughness\u003c\/li\u003e\n\u003cli\u003ePre-hardened condition eliminates the need for additional heat treatment before use\u003c\/li\u003e\n\u003cli\u003eThickness: 0.5 inches for compatibility with standard flat bar tooling setups\u003c\/li\u003e\n\u003cli\u003eWidth: 4 inches, Length: 36 inches (3 feet) for versatile cut-to-length applications\u003c\/li\u003e\n\u003cli\u003eSingle-piece packaging with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 4140 pre-hardened alloy steel flat bar suitable for general industrial fabrication, tooling, maintenance, and repair applications requiring chromium-molybdenum alloy steel stock in flat bar form.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCutting, drilling, and machining of pre-hardened 4140 steel requires carbide-tipped tooling due to its elevated hardness. Secure the bar in a proper vise or fixture before any cutting or drilling operation. Welding pre-hardened 4140 steel typically requires preheating and post-weld heat treatment to avoid cracking — consult applicable fabrication standards before welding. Always use appropriate PPE including eye protection and gloves when cutting or machining steel bar stock.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.5 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: 36 inches (3 feet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 22.54 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 30263600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: DA.5X04.0X36\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51701958902066,"sku":"DA.5X04.0X36","price":188.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bdf0224c31800520f930bb4f3ef507e3_c5f93564-0341-413a-8113-316b063613f7.jpg?v=1788407428","url":"https:\/\/voomisupply.com\/products\/value-collection-da-5x04-0x36-4140-steel-flat-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
