Products classified as premium material grades include super duplex fittings. The biphasic structural composition of the superduplex is just one of its many features and advantages. Due to their excellent microstructure, super duplex steels are twice as strong as austenitic steels. In this case, it can be seen that Super Duplex has a higher chromium and molybdenum content, which significantly improves corrosion resistance.
There are three metals present in super duplex fittings, but the amounts of these metals vary by composition. Here, the super duplex fittings include 25% chromium, 7% nickel and 4% molybdenum. Due to the high concentrations of these elements, super duplex fittings are resistant to corrosion. Super Duplex Fittings comply with all national and international standards established for this product.
The properties of super duplex fittings are listed below.
stress corrosion
Super duplex fittings are known for their excellent resistance to stress corrosion and have specific compositions.
Anti-cracking
Super duplex stainless steel is an austenitic-ferritic iron alloy containing nickel and chromium with good resistance to pitting corrosion. In addition, they exhibit very good stress and tensile strength. Both onshore and offshore applications can benefit from the use of these fittings due to their potential to perform in extremely corrosive environments.
Excellent mechanical quality
Super Duplex has good tensile strength and pitting resistance. They are extremely resilient to stressful conditions due to the super duplex function.
Durability and sturdiness
The strength and mechanical properties of super duplex stainless steel, a material that combines ferritic and austenitic grades, are improved in pipe fittings. These pipes are tough, ductile and hard, and have high tensile strength in addition to being tough. Super Duplex Fittings are known for their reliability, simplicity of installation and ease of maintenance. In addition, the welding process can be completed quickly with these fittings.
Super Duplex Fittings: Applications
Heat exchangers, pipes and fittings in oil and gas plants are just a few of the applications where super duplex fittings are suitable. Additionally, these fittings are helpful in environments where chlorides are present. Chemical tankers require super duplex fittings, which are also used for hydraulic lines, rotors and shafts. These commodities also help chemical processing facilities, marine engineering and desalination plants.
