Value Collection DB01.25X12 4140 Steel Round Rod 1.25in

Product Description

The VALUE COLLECTION DB01.25X12 is a 4140 alloy steel round rod measuring 1.25 inches in diameter and 12 inches in length. Produced with a hot rolled finish and supplied in a pre-hardened condition, this rod offers the elevated strength and wear resistance characteristic of 4140 chromium-molybdenum alloy steel. It is a general-purpose bar stock used across machining, fabrication, and tooling operations. Machinists, tool and die makers, and general fabricators work with this material when a balance of toughness and machinability is required. The pre-hardened state eliminates a separate heat treatment step for many applications.

This round rod is suited for light to medium fabrication work where 4140 alloy steel properties are specified. Typical applications include shafts, pins, bolts, studs, and general machined components in industrial and maintenance environments. The 12-inch length makes it practical for single-piece or short-run machining operations on a lathe or mill. It is appropriate for job shops, maintenance and repair operations, and prototype work requiring a controlled-composition alloy steel bar stock in a manageable cut length.

Key Features

• 4140 chromium-molybdenum alloy steel composition for high tensile strength and toughness
• Pre-hardened condition reduces the need for additional heat treatment in many applications
• Hot rolled finish suitable for general machining after surface cleanup
• 1.25-inch diameter round cross-section ready for lathe or mill operations
• 12-inch cut length convenient for single-piece machining or short-run production

Compatibility

Designed as a general-purpose 4140 alloy steel round bar stock suitable for machining, fabrication, and tooling applications where AISI 4140 material specification is required.

Installation Notes

Cutting, drilling, and turning operations on 4140 pre-hardened steel require carbide or high-speed steel tooling rated for alloy steel. Secure the workpiece firmly in a vise or chuck before machining to prevent movement. Eye protection and appropriate chip guards are required when cutting or turning. Follow your facility safety plan and applicable OSHA standards when operating metalworking equipment.
