Kunj Sheets and Plates is a prominent manufacturer and supplier of Super Duplex Steel S32760 circles in Delhi, India, renowned for providing high-performance products engineered to satisfy the needs of critical industrial processes. Our S32760 circles provide superior strength, superior corrosion resistance, and durability to last long, making them suitable to be used in highly corrosive and high-pressure environments. Carefully manufactured with rigorous testing to global standards, we supply oil & gas, chemical processing, desalination, and marine engineering industries with dependable and efficient solutions engineered to withstand the toughest service conditions.
Super Duplex Steel S32760 rings are manufactured using a highly alloyed stainless steel grade comprising around 24–26% Chromium, 6–8% Nickel, 3–4% Molybdenum, 0.2–0.3% Nitrogen, and supplemented Tungsten for superior corrosion resistance. These circles show very good mechanical properties with minimum tensile strength of 800 MPa, yield strength of 550 MPa, and elongation of 15%. The duplex microstructure of the alloy shows great resistance to stress corrosion cracking, pitting, and crevice corrosion due to its suitability for aggressive environments with chlorides and high mechanical stress.
