Latham Steel, a reputable manufacturer and supplier based in Hamilton, New Zealand, specializes in high-quality S355JO+N steel sheets and plates tailored for structural, engineering, and construction needs. This particular steel, known for its normalization, boasts high strength and exceptional toughness, along with reliable weldability and consistent mechanical performance. Latham Steel guarantees precise dimensions, a superior surface finish, and strict adherence to EN 10025-2 standards, making these plates perfect for critical load-bearing applications. With enhanced impact resistance and improved strength from normalization, S355JO+N is a popular choice for industrial projects that demand durability, stability, and long-lasting structural integrity.
S355JO+N steel features a low carbon content, complemented by controlled amounts of manganese, silicon, phosphorus, and sulfur. The “JO” designation signifies that it has been impact-tested at 0°C, while “+N” indicates normalization, which enhances toughness and refines the grain structure. This steel offers a minimum yield strength of 355 MPa and impressive tensile properties, ensuring dependable structural performance. It also provides excellent weldability, good ductility, and uniform hardness. Normalization boosts its resistance to brittle fracture, making S355JO+N a solid choice for demanding structural applications that require enhanced safety margins and stable mechanical behavior.
