This SAE Aerospace Standard (AS) defines the nomenclature for surface finishes commonly used for sheet and strip in aerospace material specifications. It is applicable to steel and to iron, nickel, cobalt, and titanium base alloys.
This specification covers manufacturing tolerances applicable to seamless and welded tubing of corrosion and heat-resistant steel. These tolerances apply to all conditions and are based on individual measurements, unless otherwise noted. Tubing may be specified by two dimensions only (OD and wall thickness, ID and wall thickness, or OD and ID).
This specification establishes a procedure for designating minimum elevated-temperature tensile property requirements of castings by means of this AMS number and a series of dash numbers.
