The AWS Class ER309/309L SAW and flux system is a specialized stainless steel welding consumable designed specifically for Submerged Arc Welding of 309/309L austenitic stainless steels. The 309L version features a low carbon content (≤ 0.03–0.04%) to minimize carbide precipitation and enhance resistance to intergranular corrosion, making it an excellent choice for cladding, overlay work, or joining dissimilar metals.
When it comes to typical weld metal composition, you can expect carbon levels around 0.03–0.04%, chromium between 23–25%, nickel from 12–14%, molybdenum up to 0.75%, manganese ranging from 1–2.5%, and silicon at about 0.3–0.65%. The mechanical properties are impressive, with a tensile strength of roughly 590 MPa, yield strength close to 400 MPa, and an elongation of around 40%, ensuring strong, durable, and corrosion-resistant welds.
