Midland Alloys Inc. is a reputable Indian producer and international supplier of Duplex Steel Tubes known for excellent performance in critical industrial applications. Duplex Steel Tubes are made from a type of stainless steel that includes both austenitic, and ferritic parts, giving them an exceptional combination of corrosion resistance and strength. These tubes exhibit excellent mechanical strength and are ideal for corrosive and high-pressure applications. We offer a wide range of grades including UNS S31803, UNS S32205, and UNS S32750, available in both duplex welded steel tubes and duplex seamless steel tubes. These tubes, also known as 22 Cr Duplex Steel Schedule 5S Tubes, have a chemical composition that balances chromium (21–23%), nickel (4.5–6.5%), molybdenum (2.5–3.5%), and nitrogen (0.14–0.20%). They provide strong performance in various industries by delivering high tensile strength (up to 620 MPa), and excellent elongation (minimum 25%). Hot Finished Duplex Tubes are part of our product line to increase dependability in challenging conditions.
