AMS vs ASTM vs UNS: How Material Specifications Cross-Reference
A single alloy can carry half a dozen spec numbers. Inconel 718, for example, appears as AMS 5662 on an aerospace purchase order, ASTM B637 in a power-generation RFQ, and UNS N07718 in a cross-reference database. Each spec number points to the same nickel-chromium composition. For engineers and procurement teams sourcing specialty metals, the difference […]

A Guide to Purchasing Inconel: Tips and Considerations
Inconel® is a family of nickel-chromium superalloys known for high strength, corrosion resistance, and oxidation resistance at elevated temperatures. Well-suited to demanding applications, Inconel alloys typically comprise 50–70% nickel, 15–25% chromium, and other elements such as iron, cobalt, molybdenum, and tungsten. The specific composition of an Inconel alloy depends on its intended applicati
