Santner Nickel Alloys, a prominent manufacturer and supplier based in Hamilton, New Zealand, offers premium Duplex Steel Screws designed for exceptional performance in demanding environments. Crafted from high-strength duplex stainless steel, these screws exhibit remarkable resistance to corrosion and stress, making them ideal for applications in harsh conditions. Our Duplex Steel Screws ensure durability, reliability, and enhanced longevity, meeting rigorous industry standards to support various industrial and construction needs with unmatched efficiency.
Mainly composed of iron, chromium (about 22-25%), nickel (about 3-5%), and molybdenum (about 3%), duplex steel chains provide a balanced microstructure of austenite and ferrite These materials provide exceptional strength, period a Tensile strength is typically between 600 and 800 MPa, with excellent resistance to corrosion and stress corrosion cracking the duplex system enhances toughness and fatigue resistance. Advantages include increased strength and weight, excellent durability, and improved corrosion resistance of chloride, making it an ideal candidate for applications in harsh environments.
