Value Collection DA1.5X12.0X12 4140 Steel Bar 1.5x12x12

Product Description

The VALUE COLLECTION DA1.5X12.0X12 is a 4140 pre-hardened steel flat bar sized at 1.5 inches thick, 12 inches wide, and 12 inches long. 4140 is a chromium-molybdenum alloy steel known for its high tensile strength, toughness, and wear resistance. The pre-hardened condition means this bar arrives ready for machining, toolmaking, or fabrication without requiring additional heat treatment. At 65.12 pounds, this is a solid, full-section piece suited for heavy-duty industrial and manufacturing applications. Machinists, tool-and-die makers, and fabricators work with this material regularly in job shop and production environments.

This bar is appropriate for applications where standard mild steel lacks the strength or hardness required. Common uses include die blocks, jigs, fixtures, mold bases, shafts, and machine components that see significant mechanical stress. Its pre-hardened state makes it suitable for direct use in toolmaking operations where dimensional stability and surface integrity are important. The 12-inch by 12-inch face and 1.5-inch thickness offer a generous cross-section for milling, drilling, or cutting to final part dimensions.

Key Features

• 4140 chromium-molybdenum alloy steel for high strength and toughness
• Pre-hardened condition — no additional heat treatment required before use
• Full cross-section at 1.5 inches thick, 12 inches wide, and 12 inches long
• Weighs 65.12 pounds — dense, full-material piece suitable for heavy structural or tooling applications
• Suitable for machining, milling, drilling, and fabrication operations

Compatibility

Designed as a general-purpose 4140 pre-hardened steel flat bar for industrial machining, toolmaking, and fabrication applications where a 1.5-inch by 12-inch by 12-inch alloy steel section is required.

Installation Notes

Handling a 65.12-pound steel bar requires appropriate lifting equipment or two-person handling to avoid injury. Secure the bar properly in a vise or fixture before cutting or machining operations. Use cutting fluids appropriate for alloy steel when machining to extend tool life and maintain surface finish. Consult applicable shop safety standards and equipment manufacturer guidelines before beginning any cutting or grinding operations.
