Andre Stainless, based in Pulau Ujong, Singapore, manufactures and supplies high-quality welding materials, including AWS Class ER385 MIG and TIG filler wire and rod. These products are made for welding highly corrosion-resistant alloys like Alloy 904L. ER385 offers excellent resistance to sulfuric, phosphoric, and organic acids. Andre Stainless guarantees that each spool or rod meets strict AWS standards for chemical makeup and weld quality. This product is perfect for critical applications in harsh settings, where long-term resistance to stress corrosion cracking and pitting is essential.
ER385 filler wire typically contains 20-22% Chromium, 24-26% Nickel, 4-5% Molybdenum, and up to 1.5% Copper, with very low carbon content (<0.02%). It has a tensile strength of about 85,000 psi (586 MPa), yield strength of around 60,000 psi (414 MPa), and 30% elongation. The composition provides great resistance to reducing and oxidizing acids and strong pitting resistance in chloride environments. This balanced mix ensures high toughness and reduces the risk of intergranular corrosion after welding.
