Value Collection DA1.0X02.0X36 4140 Steel Flat Bar

Product Description

The VALUE COLLECTION DA1.0X02.0X36 is a pre-hardened 4140 alloy steel flat bar measuring 1 inch thick, 2 inches wide, and 36 inches long. 4140 is a chromium-molybdenum alloy steel known for high tensile strength, toughness, and good fatigue resistance. The pre-hardened condition means this bar arrives ready for machining to near-final dimensions without the need for additional heat treatment cycles. It is commonly used in fabrication shops, machine shops, and industrial maintenance environments where a reliable, high-strength steel stock is required for tooling, fixtures, shafts, and structural components.

This flat bar is suited for applications demanding higher strength than mild steel can provide. Typical uses include die blocks, jigs, tool holders, machine components, and structural repair work in industrial and manufacturing settings. The 36-inch length provides a practical working stock that can be cut to multiple shorter pieces. Machinists and fabricators working with this material should plan for appropriate cutting tool selection given the hardened state of the bar.

Key Features

• 4140 chromium-molybdenum alloy steel for high strength and toughness
• Pre-hardened condition eliminates need for post-machining heat treatment
• Flat bar profile: 1 inch thick by 2 inches wide by 36 inches long
• Consistent cross-section suitable for precise machining and fabrication
• Suitable for tooling, fixtures, shafts, and structural components

Compatibility

Designed as a general-purpose 4140 pre-hardened alloy steel flat bar for use in machining, fabrication, and industrial maintenance applications requiring high-strength steel stock.

Installation Notes

Cutting and machining of pre-hardened 4140 alloy steel requires tooling rated for hardened materials, such as carbide-tipped or high-speed steel cutting tools. Always use appropriate personal protective equipment including eye protection and gloves when cutting or grinding. Secure the bar firmly in a vise or fixture before performing any machining operations. Consult applicable shop safety standards and material data sheets before processing.
