This specification covers a corrosion and heat resistant nickel alloy in the form of sheet, strip, and plate procured in inch/pound units. MAM 5598 is the metric version of this AMS. These products have been used typically for parts requiring high strength up to 1500 degrees F and oxidation resistance up to 1800 degrees F and for bellows and flat springs requiring optimum resistance to relaxation up to 1000 degrees F with moderate or relatively low stresses, particularly where welding is involved, but usage is not limited to such applications. Parts may be formed, welded if required, and then heat treated to improve strength at elevated temperatures.
