Value Collection DA1.5X02.0X12 4140 Steel Bar

Product Description

The VALUE COLLECTION DA1.5X02.0X12 is a pre-hardened 4140 alloy steel flat bar measuring 1.5 inches thick, 2 inches wide, and 12 inches long. Weighing 10.93 pounds, this bar is produced from chromium-molybdenum alloy steel to the 4140 material specification, which delivers elevated tensile strength, good machinability, and resistance to wear and fatigue compared to mild carbon steel. The pre-hardened condition means the bar ships ready for machining without a separate heat-treat step, making it a practical choice for toolmakers, machinists, and maintenance professionals working in industrial and manufacturing environments.

This bar is suited for fabrication of machine components, tooling fixtures, jigs, dies, shafts, and structural parts that require higher hardness and strength than standard low-carbon stock. The 12-inch cut length fits benchtop milling and lathe work without requiring a full stock bar. It is commonly used in job shops, maintenance and repair operations, and production environments where tight-tolerance parts are machined from pre-hardened plate or flat bar stock.

Key Features

• 4140 alloy steel specification provides superior strength and wear resistance over mild steel
• Pre-hardened condition eliminates the need for a separate heat-treat cycle before use
• Flat bar profile at 1.5 inches thick by 2 inches wide suits a wide range of milling and grinding operations
• 12-inch cut length is ready for immediate use on standard benchtop equipment
• 10.93-pound piece weight indicates dense, solid stock with consistent cross-section

Compatibility

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

Installation Notes

This bar is machined or cut to final shape by a qualified machinist or toolmaker using appropriate metalworking equipment such as milling machines, lathes, or surface grinders. Carbide or high-speed steel tooling is typically required for working pre-hardened 4140 material. Wear appropriate personal protective equipment including eye protection and gloves when cutting or grinding. Secure the workpiece firmly in a vise or fixture before machining to prevent movement and maintain dimensional accuracy.
