Value Collection DA.5X01.0X36 4140 Steel Flat Bar

Product Description

The VALUE COLLECTION DA.5X01.0X36 is a 4140 alloy steel flat bar supplied in a pre-hardened condition, measuring 0.5 inches thick, 1 inch wide, and 36 inches long. 4140 is a chromium-molybdenum alloy steel known for high tensile strength, good fatigue resistance, and solid toughness across a range of applications. The pre-hardened state means this bar ships ready for machining or direct use in fabrication without additional heat treatment, saving setup time in the shop. At 5.71 pounds per piece, it is a manageable stock length suited for small-batch work or repair stock.

This flat bar is commonly used in industrial maintenance, fabrication shops, and tooling applications where a medium-alloy steel with consistent hardness is required. Typical uses include shafts, dies, fixtures, couplings, wear plates, and machine components that demand higher strength than mild cold-rolled steel can provide. It is appropriate for both manual and CNC machining operations where dimensional stability and predictable material behavior are priorities.

Key Features

• 4140 chromium-molybdenum alloy steel for elevated tensile strength and fatigue resistance
• Pre-hardened condition eliminates need for additional heat treatment before use
• Flat bar profile simplifies fixturing and reduces material removal during machining
• 36-inch length provides a practical stock size for a wide range of part sizes
• Consistent cross-section at 0.5 inches x 1 inch suits precision layout and close-tolerance work

Compatibility

Designed as a general-purpose 4140 pre-hardened alloy steel flat bar suitable for industrial fabrication, maintenance machining, and tooling applications requiring medium-alloy steel stock.

Installation Notes

Cutting and machining of hardened alloy steel should be performed by qualified machinists using tooling rated for alloy steel hardness. Use appropriate cutting fluids to manage heat buildup and extend tool life. Secure workpieces firmly in a vise or fixture before cutting to prevent movement. Follow applicable shop safety practices and wear appropriate PPE when grinding or machining.
