Duplex Steel Screws feature a unique blend of austenitic and ferritic stainless steel, typically containing 22–25% chromium, 5–6% nickel, and 3% molybdenum. This combination results in impressive tensile strength, outstanding fatigue resistance, and excellent protection against stress corrosion cracking. They maintain their toughness in both high and low temperatures, resist pitting and crevice corrosion, and show remarkable dimensional stability under heavy loads, making them ideal for critical fastening tasks in challenging environments.
These screws find extensive use in chemical processing, offshore structures, oil and gas equipment, and marine engineering. Their ability to withstand chloride-induced corrosion makes them particularly suitable for seawater applications, heat exchangers, and pipelines. Additionally, they are perfect for high-stress industrial machinery where long-term durability and reliability are essential. The blend of mechanical strength and corrosion resistance ensures secure connections, minimizes maintenance needs, and extends the lifespan of assemblies exposed to harsh or corrosive conditions.
