Located in the industrial heart of Hamilton, New Zealand, Will Sheetsandplates is a trusted name for robust and innovative steel solutions. We take pride in supplying the exceptionally durable X120MN12 High Manganese Steel Sheet and Plate. This remarkable material is engineered for the most punishing environments, offering unparalleled impact resistance and longevity. It’s the ideal choice for local industries that demand a material which doesn’t just withstand punishment, but actually gets tougher with use.
The strength of X120MN12 comes from its unique composition, rich in manganese which gives it its characteristic work-hardening ability. When subjected to impact or high pressure, its surface becomes even harder, while the core remains ductile to prevent cracking. This combination delivers superior toughness and exceptional wear resistance, making it far more durable than conventional steels in high-stress applications where abrasion and heavy impact are constant challenges.
