Located in the heart of Hamilton, New Zealand, Hemi Metals is a trusted name for precision-engineered metal solutions. We take pride in our role as a dedicated manufacturer and supplier, specializing in high-performance materials like our Duplex Steel Bright Bar. Our focus is on providing local industries with reliable, top-tier products that meet the rigorous demands of modern engineering, combining local expertise with a commitment to exceptional quality and service.
Our Duplex Steel Bright Bar offers a unique balance, thanks to its mixed microstructure of austenite and ferrite. This composition grants it a combination of high strength and excellent resistance to corrosion, particularly against stress corrosion cracking. It is significantly stronger than standard stainless steels like 304 or 316, while also maintaining very good toughness, making it a robust and durable choice for challenging environments.
