Products Description
- Duplex steel indeed consists of two phases, ferrite and austenitic stainless steel, which contribute to its unique properties. Here are some key points about duplex steel:
- Combination of ferrite and austenitic stainless steel: Duplex steel is composed of a balanced mixture of ferrite and austenitic stainless steel phases. This combination provides the material with a desirable combination of properties, including enhanced toughness compared to pure ferritic grades.
- Superior strength: The presence of both ferrite and austenitic stainless steel phases in duplex steel contributes to its excellent strength. It offers higher strength than pure ferritic or austenitic stainless steels, making it suitable for applications that require robust mechanical properties.
- Resistance to stress corrosion cracking: Duplex steel exhibits resistance to stress corrosion cracking, which is a type of corrosion that occurs under specific conditions of tensile stress and corrosive environments. The carbon and chromium contents of the alloy contribute to this resistance, making it suitable for applications where corrosion resistance is crucial.
- Commonly used stainless steel grades: While duplex steel is distinct from stainless steel grades like 304 and 316, these grades are indeed widely used in industrial applications. Stainless steel 304 is known for its corrosion resistance and versatility, making it suitable for various applications. Stainless steel 316 offers even higher corrosion resistance, particularly in chloride environments, making it commonly used in marine and chemical processing industries.
