Latham Steel, a reliable manufacturer and supplier based in Hamilton, New Zealand, offers high-performance Sailma 350 HI sheets and plates tailored for heavy structural and engineering tasks. Sailma 350 HI is a high-strength, low-alloy steel celebrated for its remarkable toughness, weldability, and consistent performance under dynamic loads. Latham Steel guarantees precise dimensional accuracy, a uniform surface finish, and compliance with international quality standards, making these plates perfect for construction, cranes, machinery, and transport structures. With its impressive strength-to-weight ratio and enhanced impact resistance, Sailma 350 HI is a go-to choice where durability, reliability, and long-term structural stability are crucial.
Sailma 350 HI steel is crafted with controlled levels of carbon, manganese, silicon, sulfur, and phosphorus, along with microalloying elements like niobium, vanadium, or titanium. It boasts a minimum yield strength of about 350 MPa, along with outstanding tensile strength and excellent impact toughness, even in low temperatures (the “HI” signifies enhanced impact performance). This steel showcases dependable weldability, good formability, and a refined grain structure achieved through controlled rolling. Sailma 350 HI maintains consistent hardness and strong fatigue resistance, making it ideal for heavy-load and dynamic applications.
