What is AWS Class E309/309L-16 Coated Electrodes?

The AWS Class E309/309L-16 Coated Electrodes consist of about 23% chromium and 13% nickel, along with a low carbon content to avoid carbide precipitation and intergranular corrosion. The weld metal develops an austenitic structure, which offers excellent crack resistance and strength. Typically, these electrodes provide a tensile strength of around 570 MPa, along with good elongation and toughness. They are designed for use with either AC or DC+ current, ensuring smooth arc performance in all positions. The low carbon variant enhances weld integrity, particularly in high heat or corrosive environments.
