Stainless steel grades such as Super Duplex are ideal for marine and offshore applications. These alloys have high strength and low thermal conductivity, and require special machining techniques. Proper speeds and feeds are essential for efficient machining. These grades are registered trademarks of Sandvik, USA. Listed below are some of the advantages of using Super Duplex.
What is super duplex steel?
Super Duplex Steel is a high-performance alloy that has excellent resistance to acids, chlorides, and caustic solutions. It also provides superior mechanical resistance. This steel is commonly used in pipelines, valves, fasteners, oil and gas components, and pumps. It is also used in aerospace and automotive components.
Duplex steels have higher chromium and molybdenum content than austenitic stainless steels. They also exhibit higher resistance to localized corrosion. Due to these properties, the steels are also referred to as “super duplex”. Duplex steels are two-thirds chromium and one-third molybdenum, and have double the strength and ductile properties of austenitic steel.
The characteristics of Super Duplex steel make it a desirable choice for marine applications. It is resistant to corrosion and oxidation, and is easy to fabricate. Super Duplex stainless steel is extremely useful for high-temperature environments, and its corrosion resistance makes it an excellent choice for marine equipment.
