Stainless Steel AM 355 (AMS 5547 / AMS 5743)

Technical Data Sheet

AM 355 is a chromium nickel molybdenum stainless steel. AM 355 is a heat treatable austentic/ martensitic alloy (depending on the heat treatment). The properties of AM355 are that of strength of a heat treatable martensitic grades with the corrosion resistance of some of the chromium nickel austenitic grades. AM 355 is used for blades, knives, industrial cutters, discs, rotors, shafts and in similar parts where high strength is required at intermediate elevated temperatures.
