Catering to sectors like oil & gas, marine, chemical, and construction, Neith Metals has built a solid reputation for excellence, performance, and customer satisfaction.
Super Duplex Steel Round Bars are mainly made up of chromium (25%), nickel (7%), molybdenum (4%), and nitrogen, which together create a dual-phase microstructure of ferrite and austenite. This unique blend offers remarkable mechanical strength, outstanding corrosion resistance, and excellent toughness. These bars typically showcase high tensile and yield strength, ranging from 800 to 1000 MPa, along with impressive resistance to pitting, crevice corrosion, and stress corrosion cracking. Their exceptional fatigue strength and low thermal expansion make them perfect for demanding, high-pressure industrial settings.

Yes, Super Duplex Steel Round Bars can withstand moderately high temperatures but are not ideal for prolonged use above 300°C, as this may reduce their corrosion resistance and mechanical properties.
Yes, Super Duplex Steel Round Bars are highly recyclable. Their materials, including chromium, nickel, and molybdenum, can be reused, promoting sustainability and reducing waste in industrial applications.
No, Super Duplex Steel Round Bars typically do not require additional corrosion protection coatings, as their high chromium, molybdenum, and nitrogen content provides excellent inherent corrosion resistance in harsh environments.
Super Duplex Steel Round Bars find extensive use across various industries where top-notch strength and corrosion resistance are crucial. In the oil & gas sector, they are utilized in drilling equipment, heat exchangers, and offshore platforms. The marine industry relies on them for propeller shafts, fasteners, and fittings that come into contact with seawater. They are also widely used in chemical and petrochemical plants for pressure vessels, reactors, and process piping. Additionally, these round bars play a vital role in construction, desalination, and the paper & pulp industries, ensuring long-lasting performance and reliability even in extreme operating conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
