ASTM B164 UNS N04400 monel400 1.4301 round bar
Monel is particularly resistant to hydrofluoric and hydrochloric acid. It may be slightly magnetic at room temperature. Monel is more resistant to corrosion than nickel under reducing conditions and more resistant than copper when oxidized.
Compared with other alloys, Monel alloys are more resistant to reducing media than to oxidizing agents. It also exhibits resistance to alkaline, neutral, and acidic salts; however, it is less resistant to oxidizing salts such as ferric chloride. Monel 400 or Alloy 400 (UNS N04400) is a nickel-copper alloy with excellent corrosion resistance, medium/high strength and good weldability. Is Alloy 400 the same as Monel 400? Yes, Alloy 400 is the same as Monel 400.
