Product Code:SAE MAM2204
Title:Tolerances, Metric, Aluminum Alloy Standard Structural Shapes (Cancelled Jul 1989, Superseded by ANSI H35.2(M))
Issuing Committee:Ams D Nonferrous Alloys Committee
Scope: This specification covers established metric manufacturing tolerances applicable to aluminum alloy standard structural shapes ordered to metric dimensions. Standard structural shapes are shapes in certain standard alloys, tempers, sizes, and sections such as angles, channels, Tees, Zees, I-Beams, and H-Beams commonly used for structural purposes. These tolerances apply to all conditions, unless otherwise noted. This specification has been declared 'NONCURRENT' by the Aerospace Materials Division, SAE, as of September 1994. It is recommended, therefore, that this specification not be specified for new designs.
