AISI/SAE 4130 is a low-alloy steel treating chromium and molybdenum as strengthening agent. It has good strength and toughness, weldability and machinability. AISI/SAE 4130 grade is a multifunctional alloy with good corrosion resistance, shows good combinations of strength, toughness, and fatigue strength. Furthermore, AISI 4130 steel can be easily machined using conventional methods. Below are the chemical component and mechanical properties.
