For over five decades, Latham Steel has been a cornerstone of Hamilton’s industrial landscape, proudly supplying New Zealand’s toughest industries from our base in the heart of the Waikato. We understand that demanding projects require uncompromising materials, which is why we supply 450 BHN sheet and plate, a product engineered for resilience. When your work involves intense abrasion and impact, this high-strength steel is the trusted choice for building machinery that endures and performs, day in and day out.
This high-strength steel achieves its remarkable durability through a carefully balanced composition and advanced thermal processing. The result is a uniform Brinell Hardness Number of 450, a key indicator of its exceptional resistance to wear and abrasion. Alongside this impressive hardness, the material maintains crucial toughness and yield strength, providing a vital balance that prevents cracking under heavy impact. This combination makes it a robust and reliable choice for the most punishing environments.

The real-world uses for 450 BHN sheet and plate are found wherever equipment faces constant, punishing wear. You’ll see it lining dump truck bodies, guarding against heavy, abrasive loads, and forming the buckets of excavators that tackle rocky ground. In quarries and mining operations, it’s essential for constructing hoppers, chutes, and screening plants that must withstand years of impact from raw materials. Essentially, this steel is the first line of defence for any machinery that needs to last while grappling with the toughest conditions.
