Ashraf Nickel Alloys stands out as a top manufacturer and supplier of Super Duplex Steel Pipes S32750 in Riyadh, Saudi Arabia. We provide high-performance piping solutions tailored for industries that demand strength, durability, and outstanding corrosion resistance. Crafted from S32750 grade super duplex stainless steel, our pipes boast a well-balanced ferritic-austenitic microstructure, which offers remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. Available in both seamless and welded options, our pipes meet ASTM, ASME, and UNS standards, ensuring precise dimensions, high-quality finishes, and long-lasting reliability. They’re perfect for offshore, chemical, petrochemical, and marine applications where strength and corrosion resistance are essential.
Super Duplex Steel Pipes S32750 are made up of approximately 25% chromium, 7% nickel, 4% molybdenum, along with nitrogen additions, resulting in a Pitting Resistance Equivalent Number (PREN) greater than 40 for exceptional corrosion resistance. They deliver a tensile strength ranging from 795 to 1,000 MPa and a yield strength of around 550 MPa, along with impressive impact toughness, even in low temperatures. The dual-phase microstructure guarantees high fatigue resistance, dimensional stability, and excellent weldability. These pipes can handle chloride-rich, marine, and chemical environments while maintaining their structural integrity under high-pressure and high-temperature conditions, making them ideal for critical industrial and offshore pipeline applications.
