Ashraf Nickel Alloys stands out as a top manufacturer and supplier of Super Duplex Steel S32750 Coils in Riyadh, Saudi Arabia, providing high-quality solutions for critical industrial needs. Renowned for its impressive resistance to pitting, crevice corrosion, and stress corrosion cracking, S32750 is a super duplex stainless steel featuring a ferritic-austenitic microstructure, perfect for tough environments. Our coils come in both hot-rolled and cold-rolled finishes, all crafted in line with ASTM, ASME, and international standards. With exceptional mechanical strength, weldability, and durability, S32750 coils are the go-to choice for oil & gas, marine, desalination, chemical, and offshore applications that demand top-notch performance.
Super Duplex Steel S32750 Coils are made up of around 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, resulting in a Pitting Resistance Equivalent Number (PREN) of 42 or higher. They boast a tensile strength ranging from 795 to 1,000 MPa, a yield strength of about 550 MPa, and impressive impact toughness even at low temperatures. This alloy features a ferritic-austenitic dual-phase microstructure that ensures high fatigue strength, excellent thermal conductivity, and strong oxidation resistance. S32750 coils are particularly resistant to chloride stress corrosion cracking, erosion, and seawater corrosion, making them ideal for challenging industrial environments with long-lasting performance and minimal maintenance needs.
