Alloy C-276

UNS N10276 : ASTM B574 (VO2.04)

General scope

C-276 nickel alloy has a particularly high molybdenum level which combined with the tungsten addition gives it very good is crevice and pitting corrosion resistance. This makes it a particular suitable material for use in severe environments such as pollution control and chemical processing.
