AMS 6265 - Aerospace 9310 Carburizing Alloy Steel
AMS 6265 is a specification for materials in the aerospace industry that involves 9310 alloy steel bars, forgings, and billets that have been produced for carburizing in aircraft and other high-performance aircraft systems. It has established strict guidelines for the chemical composition, heat treating, and quality control of the materials in order for them to withstand the extreme environments in the aircraft industry.
It has been formulated in such a way that the alloy can be heat-treated using the carburizing process in order for the steel to have a hard outer layer and a ductile inner layer that can withstand extreme stress and pressure without breaking easily.
