The AWS Class ER316/316H MIG and TIG filler wires are made from austenitic stainless steel consumables that contain chromium (around 16–18%), nickel (10–14%), and molybdenum (2–3%) to boost corrosion resistance. The 316H grade has a higher carbon content, which enhances its strength at elevated temperatures. This unique composition offers excellent protection against pitting, crevice corrosion, and oxidation. Typically, the mechanical properties include good tensile strength, high ductility, and outstanding toughness. The weld deposits are known for their stable arc characteristics, smooth bead appearance, and strong resistance to hot cracking, even under demanding service conditions.
AWS Class ER316/316H MIG and TIG wires are commonly used for welding austenitic stainless steels in situations that require exceptional corrosion and heat resistance. They are frequently employed in the fabrication of chemical processing equipment, pressure vessels, heat exchangers, piping systems, and offshore structures. These wires are also well-suited for marine environments, pharmaceutical plants, and the food processing industry. The 316H grade is particularly effective in high-temperature applications, such as boilers and furnace components. They deliver clean, high-quality welds whether in shop fabrication or on-site work.
