自2010年7月起，SAE航空航天材料部已宣布本规范“取消”，并已被AMS 1424取代。当参考已取消的AMS 1427时，应满足最新版AMS 1424的要求。通过这一行动，本文件仍将列在航空航天材料规范索引的数字部分，并指出其已被AMS 1424取代。

This specification has been declared "CANCELLED" by the Aerospace Materials Division, SAE as of July 2010 and has been superseded by AMS 1424. The requirements of the latest issue of AMS 1424 shall be fulfilled whenever reference is made to the cancelled AMS 1427. By this action, this document will remain listed in the Numerical Section of the Index of Aerospace Material Specifications, noting that it is superseded by AMS 1424.
