Renowned for our commitment to excellence, we at Aiman Metals specialize in providing durable and corrosion-resistant Duplex Steel products to meet the diverse needs of industries such as oil and gas, marine, and chemical processing. With a focus on precision and reliability, our Duplex Steel S31803 Bars and Rods offer exceptional strength, stress corrosion cracking resistance, and excellent weldability. We stand out for our customer-centric approach, ensuring timely deliveries and superior service for all industrial applications. Our dedication to quality and service makes us a trusted partner for all your duplex steel requirements.
Duplex Steel S31803 Bars and Rods are composed primarily of 22% chromium, 5% nickel, and 3% molybdenum, with nitrogen added for enhanced strength. This alloy combines the properties of both austenitic and ferritic stainless steels, offering excellent corrosion resistance, particularly in chloride-rich environments. It provides high tensile strength (up to 620 MPa), good toughness, and resistance to stress corrosion cracking. Advantages include superior resistance to pitting, crevice corrosion, and erosion, high strength-to-weight ratio, good weldability, and cost-effectiveness compared to other stainless steels. These bars and rods are ideal for applications in marine, chemical, and petrochemical industries.
