Yes, Super Duplex Steel Zeron 100 bars can be welded. However, proper welding procedures and pre-heat treatments are essential to avoid issues like cracking and maintain its high strength and corrosion resistance.
Super Duplex Steel Zeron 100 rods are highly resistant to galvanic corrosion due to their exceptional corrosion resistance properties. However, if exposed to more active metals in a corrosive environment, some risk of galvanic corrosion may still exist.
Super Duplex Steel Zeron 100 rods are available in a range of diameters, typically from 10 mm to 300 mm, and can be customized based on specific requirements. They are commonly offered in finishes like hot-rolled, cold-rolled, and bright polished.
The remarkable properties of Zeron 100 make it the material of choice for some of the world’s toughest industries. You’ll find these bars and rods performing flawlessly in offshore oil and gas platforms, resisting the corrosive effects of seawater. They are essential in chemical processing plants handling aggressive acids, in pollution control systems like flue gas desulphurization units, and even in desalination plants that turn seawater into fresh water. Essentially, wherever extreme corrosion and high strength are non-negotiable, our Zeron 100 products provide a reliable and long-lasting solution for engineers.






We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
