Based in the heart of Hamilton, New Zealand, Will Sheetsandplates is your trusted local source for high-performance metals, with a specialized focus on Maraging Steel Sheet and Plate. We understand that true strength isn’t just about the material itself, but about the reliability of the supplier behind it. Our team is dedicated to providing not just superior product quality, but also the expert guidance and dependable service that New Zealand’s innovators need to push their most ambitious projects forward, right from our own backyard.
This remarkable steel achieves its exceptional strength through a unique heat treatment process, rather than traditional carbon hardening. Its composition is a sophisticated blend of nickel, cobalt, and molybdenum, which allows it to develop ultra-high strength while maintaining excellent toughness. After aging, Maraging Steel Sheet and Plate offers an outstanding strength-to-weight ratio and superior fracture resistance, all while being relatively easy to machine and weld in its initial, soft condition. It’s this rare combination of brawn and workability that sets it apart.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
Marraging steel sheets and plates provides many advantages such as exceptional strength, high toughness and excellent hardness. They are resistant to fatigue, shock, and stress making them more susceptible to cracking, making them ideal for aerospace, security, and equipment applications. Marezing steel also has good weldability, formability and dimensional stability at good temperatures. Its ability to retain mechanical properties for extended periods of time, coupled with its relatively low elongation and minimal distortion, makes it a desirable material for high-performance, precision-designed materials requiring machining high quality.
The unparalleled properties of Maraging Steel Sheet and Plate make it indispensable for demanding applications where failure is not an option. You’ll find it forming the core of high-performance aerospace components, critical defence systems, and advanced tooling for injection moulds that must withstand immense pressure. Beyond these, it’s the preferred choice for custom racing engines, specialised landing gear, and any pioneering prototype that requires a material as resilient and reliable as the engineering vision behind it.
