Elvis Nickel Alloys, a trusted manufacturer and supplier located in Houston, USA, specializes in high-performance Duplex Steel Pipe Fittings that are built for outstanding strength, corrosion resistance, and long-lasting reliability. Crafted from top-quality materials like UNS S31803 and S32205, these fittings boast a unique dual-phase microstructure that blends austenitic and ferritic stainless steels. This special combination offers remarkable protection against stress corrosion cracking, pitting, and crevice corrosion, particularly in environments rich in chlorides. Available in various types such as elbows, tees, reducers, caps, and stub ends, they meet international standards like ASTM A815 and ASME B16.9, making them suitable for a wide range of industries.
Duplex Steel Pipe Fittings generally consist of 22% chromium, 5–6% nickel, 3% molybdenum, and 0.15–0.20% nitrogen, along with iron and trace elements. This well-balanced chemistry guarantees excellent corrosion resistance and mechanical strength. Duplex steel can achieve tensile strength up to 750 MPa and yield strength of at least 450 MPa, along with good impact resistance even in freezing temperatures. Its microstructure enhances fatigue resistance and weldability compared to traditional stainless steels. With a high PREN (Pitting Resistance Equivalent Number), it’s perfect for challenging environments involving seawater or harsh chemicals.
