I.Overview of NS336:
alloy is a solid solution-strengthenednickel-based deformation superalloy with molybdenum and niobium as mainstrengthening elements. It has excellent corrosion resistance and oxidationperformance, and has good stretching from low temperature to 980 °C,Performance and fatigue properties, and resistance to stress corrosion undersalt spray. Therefore, it can be widely used in the manufacture of aero-enginecomponents, aerospace structural components and chemical equipment. The alloysare well processed and welded to supply a wide range of sheets, rods, tubes,wires, strips and forgings.
