What is HASTELLOY® C-4 Coated Electrodes?

HASTELLOY® C-4 Coated Electrodes are composed primarily of nickel, with significant additions of molybdenum and chromium, along with controlled amounts of iron and other elements to enhance corrosion resistance. This unique composition provides outstanding stability against strong oxidizing agents, chlorides, and stress-related cracking. Mechanically, these electrodes deliver high tensile strength, excellent ductility, and reliable toughness even under elevated temperatures. Their robust properties make them ideal for welding critical components in chemical processing, pollution control, and marine industries, where long-term durability and performance are essential.
