If you work for a manufacturer of industrial, metallic components; you could receive an enquiry for items to be manufactured from AMS 5662 and, the first time that you receive one of those; you might be totally lost as to the type of material that your prospective customer requires. Your first step will probably be to fire up your computer and do a search; possibly with no sensible results; but, you may then think that the customer has gone a bit crazy – since the search tells you that the main usage of AMS is as an abbreviation for the American Meteorological Society. Dig a little deeper and uncover other meanings for AMS; such as – American Mathematical Society; or, American Musicological Society; then it gets really weird with names like; Adult Movie Shop, Alternative Movie Society and Anti-Mugging Stick – any of which could be great fun; but have no relationship to the metal materials that you use for your component production.
Aeronautical/Aerospace Material Specification
So, in desperation, you ‘phone the buyer and he does not seem to know much about what he wants to buy; because, all he can tell you is that AMS 5662 is what is stated on the drawings and in the specifications. You ask him what usage is intended for these components and this is when the bulb lights up. His company needs your components for a project that they are undertaking for an Rockwell Aerospace Company Material Specification 5662 now makes sense and it should be easy for you to (now) find out more about it.
SAE International (Current Name For The Society of Automotive Engineers)
In your daily business; you are more than familiar with standards and specifications promulgated by SAE but you were not aware that they also have a subsection dealing (initially) with aeronautical “engines”; but, nowadays covering the whole of peaceful and military aerospace propulsion. SAE have published close to 7,000 technical documents relating to the aerospace industry; these are available as Aerospace Standards (AS); Aerospace Information Reports (AIR); Aerospace Recommended Practices (ARP); and, this is what you want; Aerospace Material Standards (AMS) which cover materials science and engineering for aerospace applications. All you have to do now; is to look up AMS 5662 and see what material it refers to.
The Answer Is Inconel
SAE detail AMS5662 as a corrosion and heat resistant alloy of nickel; but you are more familiar with it under the name of Inconel 718 (UNS N07718). As luck would have it; you already have this material in stock because it is popular with your oil and gas sector customers.
