Noah Tubefittings is a well-respected manufacturer and supplier located in Kinshasa, Congo, specializing in top-notch **Super Duplex Steel Hydraulic Fittings** that are crafted for outstanding performance in high-pressure and corrosive settings. These fittings are engineered to ensure secure, leak-proof connections in hydraulic systems that face intense mechanical stress and chemical exposure. With a strong dedication to precision manufacturing and adherence to international quality standards, Noah Tubefittings guarantees reliability, durability, and consistent performance. Their Super Duplex Steel Hydraulic Fittings have earned the trust of industries that demand robust and long-lasting solutions for fluid transfer.
Super Duplex Steel Hydraulic Fittings are made up of about 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, creating a well-balanced mix of strength and corrosion resistance. They boast impressive tensile strength (around 800–850 MPa) and yield strength (approximately 550 MPa), along with remarkable impact toughness. The duplex microstructure offers exceptional resistance to pitting, crevice, and stress corrosion cracking in environments with chloride. These fittings maintain their mechanical stability and integrity, even when faced with extreme temperatures and high-pressure situations.
