Contents of Material Specification

The contents of a material specification depend on the purpose and application of this specification. A typical AMS on a product such as an engineering alloy is identified with a Title section on the first page, followed by eight other sections Scope, Applicable Documents, Technical Requirements, Quality Assurance Provisions, Preparation for Delivery, Acknowledgment, Rejections, and Notes. 

The Title section reveals the revision history of this AMS, the type of alloy, highlights of the material characteristics, nominal composition, and heat 

The Scope section covers product form, such as sheef, sfrip, and plate, and the primary applications of fhis material, such as typically for parts requiring strength and oxidation resistance up to 816°C (1,500°E).  

The Applicable Documents section lists all the relevant documents that form part of this specification. Two SAE publications are listed in AMS 5663, which has a composition similar to that of commercial 718 nickel alloy— AMS 2261, Tolerances, Nickel, Nickel Alloy, and Cobalt Alloy Bars, Rods, and Wire, and AMS 2269, Chemical Check Analysis Limits, Nickel, Nickel Alloys, and Cobalt Alloys —along with seven other AMS publications. Also, two ASTM publications, ASTM E8M, Tension Testing of Metallic Materials (Metric), and ASTM ElO, Brinell Hardness of Metallic Materials, are listed, along with seven other ASTM publications. Therefore, to claim the conformance of AMS 5663 to the OEM design data, the comparative tensile properties should be evaluated in accordance with ASTM E8M (or its equivalence), which is part of the design document. 

The following information is included in many of the Technical Requirements sections composition, melting practice, condition of utilization, heat treatment, properties, quality, and tolerance. This is one of the core sections of many material specifications. The acceptable chemical composition is usually tabulated with the minimum and maximum elemental contents specified. The acceptable analytical methods are listed in the subsection of the composition. In AMS 5663, the weight percentage of constituent elements is required to be determined by wet chemical methods in accordance
