Santner Nickel Alloys is a reputable manufacturer and supplier of Duplex Steel Slitting Coils based in Hamilton, New Zealand. They provide top-notch materials designed for demanding industrial applications. These slitting coils undergo precise processing to ensure consistent quality, impressive strength, and outstanding corrosion resistance. With a strong commitment to quality control and adherence to international standards, Santner Nickel Alloys delivers products that you can count on for critical operations. Industries like chemical processing, oil and gas, marine, and construction rely on Duplex Steel Slitting Coils for durable, high-performance solutions that stand up to tough conditions, resisting pitting, stress corrosion, and ensuring long-term reliability.
Duplex Steel Slitting Coils are made up of about 22% chromium, 5–6% nickel, 3% molybdenum, and the rest is iron with a bit of nitrogen. Their unique dual-phase microstructure, which combines ferritic and austenitic phases, gives them remarkable mechanical strength, high yield strength, and excellent toughness. These coils are particularly resistant to pitting, crevice corrosion, and stress corrosion cracking, especially in environments rich in chlorides. They also boast great fatigue resistance, ductility, and thermal stability. This blend of mechanical and chemical properties guarantees reliable performance in tough industrial settings where strength and corrosion resistance are essential.
