AISI 4130 Alloy Steel Bars are primarily made up of chromium and molybdenum, with a carbon content usually around 0.30%. This composition provides an excellent balance of strength, ductility, and weldability. This low-alloy steel boasts good tensile strength, typically ranging from 560 to 700 MPa, and a yield strength of about 460 MPa, along with impressive toughness and fatigue resistance. Heat treatment methods like quenching and tempering further improve these mechanical properties, making 4130 bars perfect for components that need a high strength-to-weight ratio and strong resistance to wear and corrosion.
