High-performance Duplex Steel S31803 Coil and Slitting Coil are the speciality of Varun Sheets and Plates, a renowned manufacturer and supplier with headquarters in Dubai, United Arab Emirates. These coils are designed to satisfy international quality standards and are renowned for their remarkable strength, resistance to corrosion, and superior workability. Oil and gas, chemical processing, marine, and construction are just a few of the industries Varun Sheets and Plates serve. The company is a preferred option for Duplex Steel S31803 coil products in both domestic and international markets because of its dedication to quality, accurate manufacturing, and prompt delivery, which guarantees dependable and customised solutions for crucial applications.
Chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), nitrogen (~0.14–0.20%), and iron make up the balanced composition of Duplex Steel S31803 Coil/Slitting Coil. Superior corrosion resistance is provided by this alloy, particularly against pitting and stress corrosion cracking. With a minimum tensile strength of 620 MPa, a yield strength of approximately 450 MPa, and an elongation of at least 25%, it demonstrates exceptional mechanical qualities. High strength, good fatigue resistance, and weldability are guaranteed by the dual-phase microstructure of austenite and ferrite, which makes it perfect for demanding structural and corrosive environments.

Duplex steel S31803 coil/slitting coils offer a unique combination of advantages, including high strength and good corrosion resistance, especially against pitting, crack corrosion and stress corrosion cracking Their dual phase design ensures good mechanical properties, e.g higher tensile and yield strengths compared to austenitic steels reduce them in good weldability and formability, and provide they are suitable for complex applications. Furthermore, their high fatigue and corrosion resistance makes them durable in harsh environments, such as chemical manufacturing, marine, and oil and gas industries, and allows them to use time long and reliable.
Yes, we offer custom sizes for Duplex Steel S31803 Coil/Slitting Coil to meet specific project needs. Our team at Varun Sheets and Plates is dedicated to providing tailored solutions for all your requirements. For more details, contact us at sales@aaronsheetsplates.com.
Slitting and Coiling of Duplex Steel S31803 Industries that require high strength and corrosion resistance frequently use coils. In the chemical and oil and gas sectors, these coils are perfect for fabricating piping systems, storage tanks, pressure vessels and heat exchangers. Because of their resilience in salty conditions, they are utilised in the marine industry in seawater equipment, boat fittings, and offshore platforms. High-performance materials are essential for longevity and safety in pulp and paper and desalination plants, as well as in structural elements for buildings and bridges.
