Khaled Stainless, based in Cairo, Egypt, specializes in providing AWS Class ER385 MIG and TIG filler wire and rod designed for extreme corrosion conditions. Manufactured to meet AWS A5.9 / ASME SFA 5.9 standards, ER385 is the go-to filler for 904L-type and similar super-austenitic alloys, especially where resistance to sulfuric, phosphoric, and chloride-laden environments is essential. Khaled Stainless meticulously manages melting, chemistry, and spool/rod finishing to guarantee low residuals and dependable arc performance. Available in standard diameters for GMAW and GTAW, these fillers come with traceable test certificates and welding guidance tailored for chemical, fertilizer, and heavy process plant fabricators.
ER385, which corresponds to UNS N08904 / 904L chemistry as deposited, is a high-nickel, copper-bearing super-austenitic filler. The typical deposited analysis includes: C ≈0.02, Cr ≈20–21%, Ni ≈24–26%, Mo ≈4.2–4.8%, Cu ≈1.2–1.6%, Mn ≈1–2.1% (with Fe as the balance); phosphorus and sulfur levels are tightly controlled. The mechanical properties after welding usually show tensile strength in the range of ~520–600 MPa and elongation around ~30–36% (depending on the process and heat input). The low carbon content and controlled impurities help minimize the risk of hot cracking, while the copper and molybdenum enhance resistance to acid and chloride attacks.
