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 in industries that demand high strength and superior corrosion resistance. In the oil and gas industry, they are utilized for subsea equipment, pipelines, and offshore platforms. The marine sector employs them for shipbuilding, propeller shafts, and seawater cooling systems. In the chemical and petrochemical industries, they are essential for heat exchangers, pressure vessels, and storage tanks. Furthermore, construction, pulp & paper, and desalination plants depend on these bars for their durability and toughness. With excellent weldability and performance in extreme conditions, Super Duplex Steel Round Bars are the go-to choice for many applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
