This specification has been declared CANCELLED by the Aerospace Materials Division, SAE, as of November, 2007, and has been superseded by SAE AIR 4127. The requirements of the latest issue of SAE AIR 4127 shall be fulfilled whenever reference is made to the cancelled SAE AMS-STD-66. By this action, this document will remain listed in the Numerical Section of the Index of Aerospace Materials Specifications, noting that it has been superseded by SAE AIR 4127.This standard, as referenced in the applicable product specifications in procurement documents contains, a) a catalog of the standard carbon steels, alloy steels (including H-steels), and stainless and heat-resisting steels that are designed by chemical composition, or (for H-steels) by chemical composition and hardenability limits by reference to standard industry documents; and b) rules for designing the chemical content of carbon steels, alloy steels, and stainless and heat-resisting steels that are not classified as standard.
