Strategically located in the industrial heart of Hamilton, Latham Steel has built a reputation for supplying the toughest materials for the most demanding New Zealand projects. Our 700 Brinell Hardness Number sheets and plates represent the pinnacle of wear-resistant steel, offering unparalleled durability that stands up to severe abrasion and impact. We understand that our clients need more than just a product; they need a reliable partner who provides consistent quality and expert support, ensuring these high-performance materials deliver on their promise of extended service life and reduced operational downtime.
The exceptional strength of this steel comes from its specific composition, typically a high-carbon alloy enhanced with elements like chromium and boron, which is then precision heat-treated to achieve its remarkable properties. This controlled process results in a material with a consistent 700 BHN hardness across the entire plate, providing extreme resistance to wearing forces. Despite this incredible surface hardness, the steel retains good toughness, allowing it to be drilled, cut, and welded into the necessary configurations for various heavy-duty applications, balancing immense strength with practical workability.
