Andre Stainless offers AWS Class ER308 and ER308H SAW wires with corresponding flux for submerged arc welding of Type 308 stainless steels. Engineered for high-volume, high‑speed stainless welding applications, this system provides uniform arc behavior and consistent weld quality. Headquartered in Pulau Ujong, Singapore, Andre Stainless assists local shipyards, fabrication plants, and industrial workshops with prompt delivery and technical support. ER308/308H SAW system is best for general-purpose 18–8 stainless welds, featuring both common (ER308) and high–carbon creep-resistant (ER308H) grades to accommodate diverse thermal and mechanical requirements.
ER308 and ER308H wires contain 18–20% chromium and 9–11% nickel. ER308H contains slightly more carbon (≥0.04%) than ER308‘s low–carbon version. Tensile strength is generally greater than 560 MPa with elongation approximately 30%. ER308H delivers better creep resistance, while ER308 focuses on corrosion control. The flux is designed for deep penetration, weld bead shape under control, and good slag removal efficiency. They, together, make dense, smooth welds with few inclusions and high structural soundness, appropriate for SAW in flat-position continuous welding.
