Supplier — AvekGlob company — offers at various prices from the manufacturer various bulk metal — pipe, wire or circle, made of stainless steel AM-350 (ams 5548). The supplier guarantees the timely delivery of products to any address specified by the consumer /
Steel AM-350 (ams 5548) is a martensitic hardening chromium-nickel-molybdenum stainless steel. Depending on the heat treatment, the steel can have an austenitic structure, which provides increased ductility, or the martensitic structure of conventional martensitic steels. The material usually contains 5 to 10% delta-ferrite. Corrosion resistance of steel AM-350 (ams 5548) approaches the corrosion resistance of chromium-nickel steels.
Urgency of application
Steel is used for the manufacture of components of gas turbine compressors — blades, discs, rotors, shafts and the like, for the long-term operation of which high strength is required at room and moderately high temperatures. Steel AM-350 (ams 5548) also produces bellows, industrial cutters, knives, etc. products.
In accordance with the international specification UNS S35000, steel AM-350 (ams 5548) has the following chemical composition:
Carbon is 0.07… 0.11%;
Chrome — 16… 17%;
Nickel — 4… 5%;
