Barsham Nickel Alloys, situated in Doha, Qatar, is a respected producer and provider of top-class nickel alloys and specialty metals. We supply these to a variety of industries such as oil and gas, marine, and chemical processing. Our Super Duplex Steel Coils provide excellent strength, corrosion, and toughness under harsh conditions. With superior resistance to pitting and stress corrosion cracking, our coils are ideal for high-pressure, high-temperature service applications. We ensure customer satisfaction as a top priority through timely delivery, fulfilling every requirement with reliability and precision.
Super Duplex Steel Coils consist of 25% chromium, 7% molybdenum, 4% nickel, and nitrogen, with the remainder being iron. The composition offers excellent strength, superior corrosion resistance, pitting, and crevice corrosion resistance. The mechanical properties are a minimum tensile strength of 80 ksi (550 MPa) and a yield strength of 50 ksi (345 MPa). The material has a density of 7.8 g/cm³ and a melting point of approximately 1350°C (2462°F). These coils are well-suited for high-pressure, high-temperature applications, providing outstanding durability and long-term performance in demanding environments.
