Value Collection DB01.375X72 4140 Alloy Steel Round Rod

Product Description

The VALUE COLLECTION DB01.375X72 is a 4140 alloy steel round rod measuring 1-3/8 inches in diameter and 72 inches in length. This rod is produced with a hot rolled mechanical finish and delivered in a pre-hardened condition, making it ready for demanding machining, fabrication, and structural applications. 4140 alloy steel offers high tensile strength, good fatigue resistance, and solid toughness, which makes it a standard choice in industrial and maintenance environments. At 30.34 pounds, this full-length bar is suited for shops that require stock material for turning, milling, or custom component fabrication.

This round rod is commonly used in manufacturing environments, machine shops, and maintenance operations where pre-hardened alloy steel stock is needed. Typical applications include shafts, axles, spindles, pins, studs, and tooling fixtures. The 72-inch length provides flexibility for cutting multiple shorter sections or machining a single long component. Fabricators and machinists working with medium-to-heavy duty mechanical assemblies will find this bar suitable for a wide range of turned and milled parts.

Key Features

• 4140 alloy steel grade provides high tensile strength and good impact resistance
• Pre-hardened heat treatment eliminates the need for additional hardening before use
• Hot rolled finish offers a consistent surface suitable for further machining
• 1-3/8 inch diameter and 72 inch length give generous stock for multiple cut-down applications
• Weighs 30.34 pounds — full commercial bar stock weight for industrial use

Compatibility

Designed as a standard alloy steel bar stock replacement or raw material for industrial machining and fabrication applications requiring 4140 pre-hardened round rod in a 1-3/8 inch diameter profile.

Installation Notes

Cutting and machining of pre-hardened 4140 alloy steel requires carbide tooling and appropriate feeds and speeds to avoid work hardening at cut surfaces. Use proper personal protective equipment including eye protection and gloves when cutting or grinding. Secure the bar firmly in a vise or chuck before machining to prevent movement. Consult applicable shop safety standards and material data sheets before welding or heat treating this grade.
