This specification has been declared "NONCURRENT" by the Aerospace Materials Division, SAE as of September 2001. It is recommended, therefore, that this specification not be specified for new designs.

This specification covers a low-carbon steel in the form of sheet and strip coated on both faces with aluminum-silicon alloy by the hot-dip process. Primarily for low-stressed parts, such as brackets, clips, and sheathing, requiring corrosion resistance and oxidation resistance up to 1200F degrees (650C degrees).
