Monel 405 (Alloy 405, UNS N04405) Plate/Sheet Description
Monel 405 (Alloy 405, UNS N04405) Plate/Sheet is a nickel-copper alloy that has a content of cobalt and molybdenum. It has increased sulfur content than Monel 400, thus enhancing machinability into a free-cutting Monel alloy. Like Monel 400, alloy R405 is resistant to seawater and steam at high temperatures, as well as salt, and caustic solutions alkalis. It is also resistant to sulfuric acids and performs well in subzero temperatures.
There is no need for post-weld heat treatment for Monel R405. However, thorough cleaning after welding is critical for optimum corrosion resistance. Otherwise, there is the risk of contamination and embrittlement.
