Value Collection DA2.0X04.0X12 4140 Steel Bar 2x4x12

Product Description

The VALUE COLLECTION DA2.0X04.0X12 is a pre-hardened 4140 alloy steel flat bar measuring 2 inches thick, 4 inches wide, and 12 inches long. 4140 is a chromium-molybdenum alloy steel known for high tensile strength, good toughness, and resistance to wear and fatigue. The pre-hardened condition means this bar arrives ready for machining or fabrication without requiring additional heat treatment in most applications. It is commonly worked by machinists, tool and die makers, and metalworking shops that need a reliable, high-strength stock material for precision parts and tooling components.

This flat bar is suited for industrial and commercial metalworking applications where strength and dimensional consistency are required. Typical uses include fixture plates, machine components, shafts, dies, jigs, and structural tooling. At 2 inches thick and 4 inches wide, it provides substantial cross-section for heavy-duty part fabrication. The 12-inch length makes it practical for single-component blanks or short-run machining operations. Machinists working in job shops, production facilities, or maintenance departments will find this a standard stock-size piece for general-purpose alloy steel work.

Compatibility

Designed as a general-purpose 4140 pre-hardened alloy steel flat bar stock suitable for machining, tooling, and fabrication applications requiring high-strength chromium-molybdenum alloy steel.

Installation Notes

This material is typically cut, drilled, milled, or ground by machinists using carbide tooling rated for hardened alloy steels. Secure workholding is essential given the weight and rigidity of the stock. Follow applicable shop safety practices for handling heavy steel bar stock, including proper lifting technique and secure clamping before any cutting operation. No heat treatment should be assumed as part of installation unless specified by the end-use engineering requirement.
