Value Collection DA1.0X01.0X36 4140 Steel Bar 1x1x36

Product Description

The VALUE COLLECTION DA1.0X01.0X36 is a 4140 pre-hardened steel flat bar measuring 1 inch thick by 1 inch wide by 36 inches long. 4140 is a chromium-molybdenum alloy steel known for high tensile strength, good toughness, and resistance to fatigue and wear. The pre-hardened condition means this bar arrives ready for machining or fabrication without requiring a separate heat-treat cycle. It is commonly used by machinists, tool-and-die makers, maintenance technicians, and fabricators who need a reliable alloy bar stock for structural, mechanical, or tooling applications. At 11.56 pounds, this single-piece bar is practical for bench-top work or integration into a larger fabrication workflow.

This 4140 pre-hardened flat bar suits a wide range of industrial and maintenance applications including shafts, pins, tooling fixtures, brackets, machine components, and wear plates. Its square cross-section profile makes it straightforward to clamp, mill, drill, or turn on a lathe. It is appropriate for both job-shop environments and in-house maintenance departments that require consistent, ready-to-machine alloy steel bar stock. Each unit ships as a single 36-inch length.

Key Features

• 4140 chromium-molybdenum alloy steel for high strength and wear resistance
• Pre-hardened condition eliminates the need for post-purchase heat treatment
• Uniform 1 inch x 1 inch cross-section for predictable machining and clamping
• 36-inch length provides flexibility for single-piece or cut-to-length applications
• Consistent alloy specification supports applications requiring tight mechanical tolerances

Compatibility

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

Installation Notes

Cutting, drilling, or machining 4140 pre-hardened steel requires carbide-tipped tooling due to the elevated hardness of this alloy condition. 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 machining to prevent movement. Consult applicable workplace safety standards and material safety data when welding or grinding 4140 alloy steel.
