Specializing in providing dependable solutions for oil and gas, marine, and chemical industries, we cater to various customer requirements. Our Super Duplex Steel Screws provide excellent corrosion resistance, strength, and durability, making them suitable for harsh applications in high-pressure conditions. We guarantee on-time delivery, with our customers receiving the finest quality high-performance screws that satisfy the strictest demands.
Super Duplex Steel Screws consist of 25-30% chromium, 6-7% nickel, 3-5% molybdenum, and 0.2-0.3% nitrogen, offering outstanding strength and corrosion resistance. They possess mechanical properties such as tensile strength of up to 800 MPa, yield strength of about 550 MPa, and superior ductility. Physical properties exhibit a density of 7.8 g/cm³, superior resistance to chloride stress corrosion cracking, pitting, and crevice corrosion. These screws work outstandingly well in high-temperature, high-pressure applications and are therefore perfectly suited for industries like oil and gas, chemical processing, and marine engineering
