Elvis Nickel Alloys, located in Houston, USA, stands out as a leading manufacturer and supplier of Super Duplex Steel Slitting Coils. These coils are specifically crafted for tough industrial applications that demand exceptional mechanical strength, corrosion resistance, and precise dimensions. Utilizing advanced grades like UNS S32750 and UNS S32760, these slitting coils boast a unique dual-phase austenitic-ferritic microstructure, ensuring top-notch performance even in harsh environments rich in chlorides, acids, and marine conditions. They are produced in accordance with global quality standards such as ASTM A240, ASTM A276, and EN 10088, making them a go-to choice in industries like chemical processing, desalination, oil & gas, and marine engineering.
Super Duplex Steel Slitting Coils are typically made up of 24–26% chromium, 6–8% nickel, 3–5% molybdenum, 0.2–0.3% nitrogen, along with trace elements like manganese, silicon, and copper. This high-alloy mix provides impressive tensile strength of up to 800 MPa, yield strength of at least 550 MPa, and elongation of 25% or more. The duplex structure significantly boosts resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides, while also ensuring excellent impact toughness in both high and sub-zero temperatures. These coils are perfect for applications that require durability and longevity in challenging environments.
