Super Duplex Steel Screws are produced from a harmonized combination of austenitic and ferritic stainless steels, offering mechanical strength coupled with superior corrosion resistance. They possess very high tensile strength, superior hardness, and superior fatigue resistance. These screws provide performance at both high and low temperature levels and are resistant to pitting, crevice corrosion, and stress corrosion cracking, especially in environments rich in chlorides. Their enhanced strength-to-weight ratio means they are lighter than standard stainless steel screws but have high mechanical toughness, thus being well-fitted for high-stress, high-pressure, and corrosive industrial applications.
Super Duplex Steel Screws are commonly used in high-strength, corrosion-resistant, and reliable industries. In chemical processing, they are resistant to aggressive chemicals and pressures. In marine applications, they resist corrosion by seawater, providing long life during service. Under high tension, these screws offer safe fastening in the oil and gas sector. They are also applied in the power generation and building industries, where operating conditions are harsh, requiring long-lasting, high-performance fasteners. Their strength, reliability, and corrosion resistance make them perfect for demanding and critical applications in industry.
