Latham Steel, a trusted manufacturer and supplier based in Hamilton, New Zealand, specializes in high-strength MAXIL 690 sheets and plates that are perfect for tough structural, engineering, and heavy-duty applications. MAXIL 690 is a quenched and tempered high-strength steel, celebrated for its remarkable toughness, impressive yield strength, and reliable performance even under extreme loads. Latham Steel guarantees precise dimensions, a consistent surface finish, and full adherence to international quality standards. These plates are ideal for crane structures, lifting equipment, heavy machinery, trailers, and advanced engineering projects that demand lightweight yet incredibly strong steel with long-lasting durability and resistance to fatigue.
MAXIL 690 steel is crafted with low carbon levels and a mix of alloying elements like manganese, nickel, chromium, and molybdenum, which boost its hardenability, strength, and impact resistance. After undergoing quenching and tempering, this material achieves a minimum yield strength of around 690 MPa, along with excellent tensile strength. MAXIL 690 is known for its high toughness, uniform hardness, and strong resistance to brittle fracture. Despite its impressive strength, it remains weldable when proper heat-control procedures are followed. Its refined microstructure ensures consistent performance in applications that are highly stressed, fatigue-sensitive, and dynamically loaded.
