自2007年4月起，SAE航空航天材料部已宣布本规范“取消”，并已被ASTMD A 439取代。当参考已取消的SAE AMS 5393时，应满足最新版ASTM A 439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ASTMD A 439取代。

This specification has been declared "CANCELLED" by the Aerospace Materials Division, SAE, as of April 2007, and has been superseded by ASTMD A 439. The requirements of the latest issue of ASTM A 439 shall be fulfilled whenever reference is made to the cancelled SAE AMS 5393. By this action, this document will remain listed in the Numerical Section of the Index of Aerospace Material Specifications noting that it has been superseded by ASTMD A 439.
