AWS Class ER309/309L is a stainless steel welding wire primarily made up of 23–25% Chromium, 12–14% Nickel, and a low Carbon content (≤0.03%). This specific composition offers outstanding resistance to corrosion and oxidation, particularly in high-temperature settings. The low carbon content helps to reduce carbide precipitation, which in turn minimizes the risk of intergranular corrosion. Typical mechanical properties include a tensile strength of about 550 MPa (80 ksi), a yield strength of roughly 350 MPa (51 ksi), and an elongation of 30% or more. ER309/309L provides stable arc characteristics and a smooth weld bead finish, making it ideal for critical welding applications.
