Key Features & Applications of UNS N04400 Buttweld Fittings

Monel Buttweld Fittings 400 is resistant to corrosion by hydrofluoric and hydrochloric acids, alkalis and seawater. They are easy to fabricate, and ductile because they can only be hardened by cold working, as well as, high thermal conductivity. UNS N04400 buttweld fittings have very low corrosion rates in flowing marine water, which is why they are the most favored in marine engineering, offshore desalination, chemical processing, oil refinery piping, pharmaceutical manufacturing, and heat exchanger. They are weakly magnetic at ambient temperature and provide a melting temperature of 1300- 1350 °C.
