AM-355 ams 5547 pipe, wire, circle
Supplier — AvekGlob Company — offers pipe, wire and a circle, made of stainless steel AM-355 (ams 5547) at an affordable price from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Steel AM-355 (ams 5547) is a chromium-nickel-molybdenum stainless steel. Depending on the heat treatment regime, it can have an austenitic or martensitic structure. A peculiarity of the properties of this steel is the optimal combination of strength parameters characteristic of the strength of heat-treated martensitic grades with corrosion resistance of some grades of austenitic grades of chromium-containing steels.
Urgency of application
Steel AM-355 (ams 5547) is used for the production of blades, knives, industrial cutters, discs, blades and rotors, shafts and the like, where high strength is required at intermediate elevated temperatures. The operating temperature of the application should not exceed 535… 540 0 С.
In accordance with the specification AMS 5547, steel AM-355 (ams 5547) has the following chemical composition (iron — the rest):
Carbon — 0.10… 0.15%;
