Sumer Metal Industries Pvt. Ltd., based in Mumbai, India, is a leading manufacturer, supplier, and exporter of high-quality Super Duplex Steel S32750 Needle Tubes. Known for their superior strength and corrosion resistance, these tubes are designed to meet the demanding requirements of modern industries. The company has a strong presence in international markets, exporting to countries such as Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and several regions across Africa.
Super Duplex Steel S32750, also referred to as UNS S32750 or SAF 2507, is a highly alloyed steel that combines the beneficial properties of both austenitic and ferritic stainless steels. This makes it exceptionally resistant to pitting, crevice corrosion, and stress corrosion cracking, even in harsh environments. The alloy’s balanced microstructure enhances its mechanical strength, making it ideal for high-pressure and high-temperature applications.
These needle tubes find extensive use in critical industries including oil and gas, chemical processing, desalination plants, and marine engineering. Their high corrosion resistance makes them suitable for handling aggressive chemicals, seawater, and acidic environments. In the oil and gas sector, S32750 tubes are often used for tubing, piping, and heat exchangers where reliability and longevity are crucial.
Super Duplex Steel S32750 Needle Tubes are available in a wide range of dimensions to accommodate various industrial requirements. Standard outer diameters range from 6 mm to 50 mm, with wall thicknesses from 0.5 mm to 5 mm. Tube lengths typically vary from 1 meter to 6 meters, and custom sizes are available upon request. Surface finishes include polished, pickled and passivated, or mill finish depending on the application.

The chemical composition of S32750 is carefully controlled to achieve optimal performance. It contains 24–26% chromium, 6–8% nickel, 3–5% molybdenum, and 0.24–0.32% nitrogen, along with minor elements such as manganese, silicon, phosphorus, and sulfur. Iron makes up the balance of the alloy. This composition provides excellent resistance to localized corrosion and ensures high mechanical strength in demanding environments.
