Value Collection DA.75X04.0X36 4140 Steel Flat Bar

Product Description

The VALUE COLLECTION DA.75X04.0X36 is a 4140 alloy steel flat bar supplied in a pre-hardened condition, measuring 0.75 inches thick, 4 inches wide, and 36 inches long. Weighing 34 pounds, this bar is ready for machining, fabrication, or tooling applications where elevated strength and wear resistance are required. The 4140 grade combines chromium and molybdenum alloying elements to deliver high tensile strength, good toughness, and reliable fatigue resistance compared to plain carbon steel. It is stocked in pre-hardened form, eliminating the need for additional heat treatment before use in most tooling and fixture applications.

This flat bar is suited for industrial and trade fabrication environments where a machine-ready steel blank is needed. Typical applications include die blocks, fixtures, jigs, shafts, and structural machine components. The 36-inch length provides a usable blank that can be cut to final dimensions on a bandsaw or cold saw. It is appropriate for use in general metalworking shops, industrial maintenance operations, and HVAC or mechanical equipment fabrication where custom steel components must be machined from bar stock.

Key Features

• 4140 chromium-molybdenum alloy steel for high tensile strength and toughness
• Pre-hardened condition eliminates additional heat treatment in most applications
• 0.75 inches thick by 4 inches wide flat bar profile for versatile machining
• 36-inch length provides a full usable blank for cutting to final dimensions
• 34-pound bar weight supports heavy-duty structural and tooling uses

Compatibility

Designed as a general-purpose 4140 pre-hardened steel flat bar blank suitable for machining into custom components, fixtures, and tooling in industrial and mechanical fabrication settings.

Installation Notes

Cutting and machining of pre-hardened 4140 steel requires carbide tooling or appropriate high-speed steel rated for hardened materials. Wear appropriate PPE including eye protection and gloves when cutting or grinding. Secure the bar firmly in a vise or fixture before any cutting operation. Consult applicable shop safety standards and equipment manufacturer guidelines before processing.
