Leading Industrial Supplier of HASTELLOY® C-4 Coated Electrodes For Welding Solutions in Tunis
HASTELLOY® C-4 coated electrodes are made from a nickel-chromium-molybdenum alloy with very low levels of carbon and silicon, enhancing both weldability and corrosion resistance. This carefully balanced composition provides outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, especially after welding. The electrode coating ensures stable arc characteristics, a smooth weld bead appearance, and easy slag removal. Weld deposits typically show high tensile strength, good ductility, and excellent toughness, maintaining their mechanical stability even under thermal cycling and exposure to aggressive chemicals.
