Yes, Super Duplex Steel Hex Bars are magnetic due to their mixed microstructure of austenite and ferrite, which gives them magnetic properties, though they are less magnetic than ferritic steels.
Yes, Super Duplex Steel Hex Bars are suitable for hygienic and sanitary applications due to their corrosion resistance, durability, and ease of cleaning, making them ideal for industries like food processing and pharmaceuticals.
Super Duplex Steel Hex Bars are less susceptible to galvanic corrosion compared to other materials due to their high corrosion resistance. However, they may still experience galvanic corrosion when in contact with less resistant metals.
Super Duplex Steel Hex Bars are widely used in industries that demand high strength, corrosion resistance and durability. They are particularly favored in the marine industry. For applications such as shipbuilding, offshore platforms and subsea equipment. Where resistance to seawater corrosion is critical. In the oil and gas industry they are used for pressure vessels, heat exchangers and valves ensuring long-term reliability in harsh conditions. The chemical processing sector also relies on Super Duplex Steel Hex Bars for equipment that handles aggressive chemicals. Other industries, including power generation and desalination, use this material for its excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
