Value Collection CB04.5X12 Alloy Steel Round Rod

Product Description

The VALUE COLLECTION CB04.5X12 is a 4140 alloy steel round rod measuring 4.5 inches in diameter and 12 inches in length. It carries a hot-rolled mechanical finish and has been annealed for improved machinability and reduced internal stress. At 55.61 pounds, this is a substantial bar-stock section suited for heavy-duty machining, fabrication, and tooling applications. Grade 4140 alloy steel is a chromium-molybdenum steel known for high tensile strength, good toughness, and solid response to heat treatment. Machinists, fabricators, and tool-and-die shops are the primary users of this material form.

This round rod is appropriate for general industrial and manufacturing use where a pre-cut bar-stock blank is needed for turning, milling, or further heat treating. The annealed condition makes it easier to machine or cold-work before final hardening. Typical applications include shafts, pins, tooling components, die blocks, and structural inserts in both one-off and short-run production environments. The 12-inch length provides a manageable starting blank for lathe work or can be cut down to final part length as required by the job.

Key Features

• Grade 4140 chromium-molybdenum alloy steel for high strength and toughness
• Annealed heat treatment reduces hardness and improves machinability
• Hot-rolled finish — ready for machining or further processing
• 4.5-inch diameter provides substantial cross-section for heavy-duty components
• 12-inch cut length suits lathe blanks, die blocks, and structural inserts
• UNSPSC Code 30102404 for procurement and inventory classification

Compatibility

Designed as a standard bar-stock blank compatible with conventional metal lathes, milling machines, and machining centers capable of handling 4.5-inch diameter stock. No specific system or equipment model compatibility is stated by the manufacturer for this material form.

Installation Notes

Handling of round bar stock at this diameter and weight requires appropriate lifting equipment or a second person to prevent injury. Machining of 4140 alloy steel should be performed by qualified machinists using tooling rated for alloy steel. If subsequent heat treatment is planned, follow the material supplier's recommended thermal cycle parameters. Secure workholding in the lathe chuck or fixture is essential given the mass of the workpiece.
