Nakamura Stainless in Pulau Ujong, Singapore, supplies AWS Class ER385 MIG and TIG Filler Wires and Rods, also known as “Alloy 904L” consumables, made for highly corrosive environments. These contain high levels of nickel, chromium, and molybdenum, plus copper, allowing superior resistance to reducing acids like sulfuric acid. ER385 is designed for welding high-alloy stainless steels where resistance to pitting, crevice, and stress corrosion cracking is critical. With stable arc characteristics and quality bead formation, Nakamura Stainless ensures these consumables meet international standards, making them ideal for demanding chemical and marine applications.
AWS Class ER385 wires and rods contain 19–21% chromium, 24–26% nickel, 4–5% molybdenum, and 1–2% copper, with low carbon levels. This combination offers great resistance to reducing acids, chloride-induced stress corrosion cracking, and pitting. Weld deposits typically show tensile strength of around 550–600 MPa and elongation of 30–35%, providing strength and toughness in hard conditions. They also maintain strong resistance to crevice corrosion and keep their stability under thermal stress. These properties make them effective for welding high-alloy stainless steels in harsh environments.
