Applications & Benefits of Super Duplex Steel S32750 Fasteners
Super Duplex Steel S32750 Fasteners offer superior mechanical properties compared to conventional austenitic stainless steel fasteners. It has an excellent combination of high strength and corrosion resistance, which makes it an ideal choice in highly corrosive environments. It offers superior pitting resistance in chloride-containing environments due to its high chromium content (up to 25%) and molybdenum content (up to 5%). The high molybdenum content increases its resistance to localized attacks such as pitting corrosion or crevice corrosion. Additionally, this grade of fastener can be welded without any pre- or post-weld heat treatment due to its low carbon content (< 0.03%).
Applications of Super Duplex Steel S32750 Fasteners
Super Duplex Steel S32750 Fasteners are widely used in many industries, including the oil & gas industry; petrochemical industry; chemical processing industry; marine engineering; power generation industry; food processing industry; etc. These fasteners are highly resistant to chloride-induced stress corrosion cracking (SCC), making them suitable for use in saltwater environments. They are also suitable for use in sour service conditions because they have excellent resistance to sulfide stress cracking (SSC). Additionally, these fasteners have the ability to withstand high temperatures up to 600°F, which makes them suitable for use in extreme temperature applications.
Benefits of Super Duplex Steel S32750 Fasteners
The main benefit of using SDS S32750 Fasteners is that they offer superior strength and corrosion resistance compared to conventional austenitic stainless steel fasteners. This makes them perfect for use in highly corrosive environments where conventional stainless steel fasteners may not be able to provide adequate protection against corrosion or where weight savings is important due to their lighter weight when compared with other materials such as carbon steel or alloy steel fasteners. Additionally, they offer excellent weldability, making them easy to install without any pre- or post-weld heat treatments required, which can help reduce installation time significantly.
Super Duplex Steel S32750 Fastener offers superior strength and excellent corrosion resistance compared with traditional austenitic stainless steels such as 316L. This grade of fastener can withstand harsh environmental conditions such as those encountered offshore and onshore oil & gas production facilities providing long-term reliability even under extreme conditions. Furthermore, their lightweight design allows for significant weight savings over heavier materials like carbon steel or alloy steel. Additionally, these fasteners offer excellent weldability, which helps reduce installation time, helping save both labor costs and time.
