本规范涵盖了以SI（公制）单位采购的棒材、锻件、闪光焊环和锻坯、闪光焊环或镦头形式的耐腐蚀耐热镍合金。AMS 5706是该MAM的英寸/磅版本。这些产品通常用于要求高强度高达815摄氏度、抗氧化性高达955摄氏度的零件，如紧固件、法兰和环，尤其是那些成型或焊接后进行热处理以获得所需性能的零件，但用途不限于此类应用。

This specification covers a corrosion and heat resistant nickel alloy in the form of bars, forgings, flash welded rings, and stock for forging, flash welded rings, or heading procured in SI (metric) units.AMS 5706 is the inch/pound version of this MAM. These products have been used typically for parts, such as fasteners, flanges, and rings, requiring high strength up to 815 degrees C and oxidation resistance up to 955 degrees C, particularly those parts which are formed or welded and then heat treated to develop required properties, but usage is not limited to such applications.
