Latham Steel, a reputable manufacturer and supplier located in Hamilton, New Zealand, specializes in high-performance 400 Brinell Hardness Number (BHN) Sheets and Plates designed for tough wear conditions. These abrasion-resistant plates are known for their remarkable hardness, durability against impacts, and long-lasting performance even under constant friction, material flow, and heavy mechanical stress. Latham Steel guarantees precise processing, consistent hardness, and adherence to international quality standards, making these plates perfect for industries like mining, construction, quarrying, and heavy machinery. With a dependable supply chain and rigorous quality control, Latham Steel provides 400 BHN plates that minimize downtime, prolong component life, and enhance overall operational efficiency.
400 BHN Sheets and Plates are crafted from high-strength, abrasion-resistant alloy steel that features increased levels of carbon and manganese, along with alloying elements such as chromium, boron, and molybdenum to boost hardness and toughness. This material reaches a Brinell hardness of around 400 HBW, delivering excellent resistance to sliding wear, impacts, and abrasive forces. Its mechanical properties include high tensile and yield strength, impressive impact toughness, and reliable performance under continuous load stress. Despite their extreme hardness, these plates can be shaped using the right cutting, forming, and welding techniques, making them ideal for demanding industrial applications.
