Value Collection DA2.0X02.0X12 4140 Steel Bar 2x2x12 in

Product Description

The VALUE COLLECTION DA2.0X02.0X12 is a 4140 alloy steel flat bar supplied in a pre-hardened condition, measuring 2 inches thick by 2 inches wide by 12 inches long and weighing 14.5 pounds. 4140 is a chromium-molybdenum alloy steel known for high tensile strength, toughness, and resistance to wear and fatigue. The pre-hardened state eliminates the need for additional heat treatment before use in most applications. This bar is commonly worked by machinists, toolmakers, and metalworking shops that require a reliable, consistent steel stock for precision components.

This bar is suited for machining fixtures, jigs, tooling plates, dies, shafts, and structural machine components where a higher-strength alloy steel is required. At 12 inches in length, it is well sized for short-run prototype work or replacement part fabrication. Industrial maintenance shops, job shops, and production facilities regularly stock 4140 pre-hardened bar for on-demand machining of wear parts and mechanical components. The square cross-section simplifies setup on mills and lathes.

Key Features

• 4140 chromium-molybdenum alloy steel for high strength and toughness
• Pre-hardened condition ready for machining without additional heat treatment
• Square cross-section at 2 inches x 2 inches simplifies fixturing and setup
• 12-inch length suitable for prototype and short-run component fabrication
• 14.5-pound bar weight indicates dense, solid stock with no voids

Compatibility

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

Installation Notes

Cutting and machining of 4140 pre-hardened steel requires carbide tooling and appropriate cutting speeds to preserve tool life and surface finish. Secure the workpiece firmly in a vise or fixture before machining operations begin. Welding pre-hardened 4140 requires preheat and post-weld heat treatment procedures per applicable welding codes to avoid cracking. Always use appropriate PPE including eye protection and gloves when cutting or grinding steel bar stock.
