Easy-to-Weld 4130 Alloy Steel Rods

Yield Strength: Not Rated
Hardness: Rockwell C21 (Hard)
Fabrication: See table
Specifications Met: See table

Made from 4130 alloy steel, also known as chrome-moly steel, these rods have low carbon content for good weldability. They’re often used to make gears and bushings. The surface of these rods is hardened to make them more resistant to wear and impacts. They’re also normalized, which is a heating process that relieves internal stress and helps prevent cracking during machining or additional hardening. These rods have been manufactured to ASTM and SAE standards for quality and performance.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
