Latham Steel, a reliable manufacturer and supplier located in Hamilton, New Zealand, specializes in high-quality S355JO steel sheets and plates designed for structural, construction, and engineering needs. S355JO is a low-alloy, high-strength structural steel recognized for its impressive toughness, excellent weldability, and consistent mechanical performance. The “JO” impact rating guarantees reliable toughness at 0°C, making it a great choice for moderate-temperature settings. Latham Steel is committed to delivering precise dimensions, a consistent surface finish, and compliance with EN 10025 standards. Thanks to its outstanding strength and versatility, S355JO is perfect for load-bearing structures, fabrication tasks, and industrial projects that demand durability and long-lasting reliability.
S355JO steel features low carbon content along with controlled amounts of manganese, silicon, phosphorus, and sulfur. It boasts a minimum yield strength of 355 MPa and impressive tensile properties, making it ideal for structural applications. The “JO” designation signifies that the steel has successfully undergone Charpy V-notch impact testing at 0°C, ensuring reliable toughness. This material offers good weldability, uniform hardness, and stable ductility, making it perfect for structural fabrication. With its refined grain structure, S355JO performs consistently well under moderate dynamic loads and varying environmental conditions.
