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 established manufacturing tolerances applicable to sheet, strip, and plate of corrosion and heat resistant steels, iron alloys, titanium, and titanium alloys ordered to inch dimensions. These tolerances apply to all conditions, unless otherwise noted. The term “excl” is used to apply only to the higher figure of the specified range.
This specification, in conjunction with the general requirements for steel heat treatment covered in AMS2759, establishes the requirements for annealing of austenitic corrosion-resistant steel parts. Parts are defined in AMS2759. General ordering instructions are specified in AMS2759.
