Description of material
V225MN is a Molybdenum and Nitrogen alloy ferritic-austenitic stainless steel whose duplex structure containing approximately the same amounts of Ferrite and Austenite is able to provide a good pitting and uniform corrosion resistance, as well as very good stress corrosion cracking resistance, together with high mechanical properties and toughness.
Applications
Pump and valve parts, pressure vessels, desalination plants, tanks, bolts, nuts, rings, stirrers, hollows bars handling solutions containing Chloride, marine environments, boat shafts where corrosion fatigue resistance is required, and reinforcing bars for structural application such as roads, bridges, harbors landing zones, and buildings.
