Nestled in the industrial heart of Hamilton, Hemi Metals is proud to be a trusted local source for high-performance materials. We understand that robust, reliable components are the backbone of strong industry, which is why we specialise in supplying top-tier Duplex Steel Hex Bars. Our commitment is to provide New Zealand’s engineers and manufacturers with products that combine exceptional strength with real-world durability, backed by the personalised service that comes from being part of the community.
Duplex Steel gets its name from a balanced microstructure of austenite and ferrite, giving it a remarkable combination of qualities. This material boasts a high tensile and yield strength that surpasses standard stainless grades, providing excellent resistance to stress corrosion cracking. It also maintains very good toughness and offers strong general corrosion resistance, making it a robust and dependable choice for challenging environments where both strength and corrosion resistance are non-negotiable.

Yes, Duplex Steel Hex Bars are fully recyclable. They can be melted down and reused without losing their essential properties, making them an environmentally sustainable option for various applications.
Duplex Steel Hex Bars have inherent corrosion resistance due to their composition. However, in highly aggressive environments, additional coatings or treatments may be necessary to enhance their longevity and performance.
To choose the right Duplex Steel Hex Bar, consider factors such as mechanical strength, corrosion resistance, temperature conditions, and compatibility with your application’s specific industry standards and environmental factors.
The superior properties of Duplex Steel Hex Bar make it a go-to material for demanding applications across numerous sectors. You’ll find it machined into vital components for the offshore and marine industries, chemical processing plants, and oil and gas equipment. Its strength and corrosion resistance also make it ideal for structural parts in bridges and building projects, as well as for high-stress fasteners, shafts, and valves that need to perform reliably under pressure and in harsh conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
