AM 355 is a chromium nickel molybdenum stainless steel，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.
It offers high strength at moderately elevated temperatures and its corrosion resistance is superior to other quench-hardenable martensitic stainless steels. Higher strengths can also be obtained through cold working processes.
Alloy AM-355 has been used for gas turbine compressor components such as blades, rotors and shafts. Alloy AM-355 has good resistance to atmospheric corrosion and to a number of other mild chemical environments.

AM-355 (634 type) stainless steel is a semi austenitic precipitation hardening type stainless steel with excellent mechanical properties and corrosion resistance. It is composed of elements such as chromium, nickel, molybdenum, vanadium, and niobium, among which the addition of niobium can improve its strength and corrosion resistance.
The mechanical properties of AM-355 stainless steel are excellent, with high yield strength, tensile strength, and elongation. At the same time, it also has excellent corrosion resistance and performs well in harsh environments such as hydrogen corrosion, hydrogen sulfide corrosion, and chloride stress corrosion.
AM-355 stainless steel is commonly used for manufacturing high-strength bolts, bearings, springs, valves, and other parts and components. It is also commonly used in the manufacturing of high-strength structural components in industries such as aerospace, shipbuilding, and petrochemical. However, it should be noted that due to the continued precipitation of intermetallic compounds above 315 ℃ during long-term use, the material becomes brittle, so the use temperature needs to be limited to below 315 ℃.
