Value Collection DA.5X01.5X36 4140 Steel Flat Bar

Product Description

The VALUE COLLECTION DA.5X01.5X36 is a pre-hardened 4140 alloy steel flat bar intended for tooling, fixturing, die components, and general machining applications where higher hardness and improved wear resistance are required compared to mild steel. The bar measures 0.5 inches thick, 1.5 inches wide, and 36 inches long, yielding a manageable 3-foot length that suits both bench-shop and production-floor use. Pre-hardening eliminates the need for heat treatment after machining in many applications, saving time and reducing distortion risk. Machinists, tool-and-die makers, and maintenance technicians working in industrial and fabrication environments are the primary users of this material.

This flat bar is suited to applications that demand toughness and fatigue resistance beyond what low-carbon steel provides. Typical uses include wear plates, die blocks, shafts, keys, pins, and structural machine components. The 4140 chromium-molybdenum alloy specification provides a balance of hardness, strength, and machinability. At 0.5 inches thick by 1.5 inches wide, the cross-section is commonly found in jig and fixture construction as well as light tooling and repair stock in job shops and maintenance departments.

Key Features

• 4140 chromium-molybdenum alloy steel for improved toughness and fatigue strength over mild steel
• Pre-hardened condition reduces or eliminates post-machining heat treatment in many applications
• Flat bar profile at 0.5 inches thick by 1.5 inches wide suits wear plates, keys, and die components
• 36-inch length provides a practical 3-foot stock piece for cutting to finished dimensions
• Weighs approximately 8.44 pounds per bar for straightforward handling and shipping

Compatibility

Designed as a general-purpose 4140 pre-hardened alloy steel flat bar suitable for tooling, die making, and machined-component fabrication applications where 0.5 inch by 1.5 inch cross-section stock is specified.

Installation Notes

Cutting, drilling, and machining should be performed with tooling rated for hardened alloy steel. Carbide or high-speed steel tooling is typically required. Standard shop safety practices apply, including eye protection and chip containment. Consult applicable workplace safety and material-handling guidelines when cutting or grinding hardened steel stock.
