Nickel alloy 200 is a solution-strengthened, commercially-pure material. The alloy demonstrates good mechanical properties over a fairly wide range of temperatures. The alloy has excellent corrosion resistance to alkaline solutions and high velocity flowing seawater; however stagnant or low velocity seawater will severely attack N200. Service temperatures should be limited to less than 600 °F. The alloy is used in the chemical and petro-chemical industries.
