AMS 5616 - Greek Ascoloy Stainless Steel
AMS 5616 is an SAE International specification for Greek Ascoloy (UNS S41800), a hardenable martensitic stainless steel engineered for high-stress, heat-resistant aerospace applications up to 1200°F (649℃). It is widely used in gas turbine compressor blades, fasteners, and other critical components requiring superior creep strength, corrosion resistance, and high-temperature performance.
