Description
Introduction:
AMS 5655 is a hardenable stainless steel designed for use at temperatures of up to 650 ºC. AMS 5655 has good resistance to scaling and oxidation. Through heat treatment, high mechanical properties can be developed. AMS 5655 is used in applications such as compressors or steam turbines and also in aircraft parts, valves, high temperature bolting, and other mechanical parts used in high temperature circumstances.
The alloy is usually produced by BEF & AOD followed by electroslag remelting (ESR) / VAR if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
