Latham Steel, based in Hamilton, is a trusted name for industrial strength and reliability. We are proud to supply local manufacturers and workshops with our premium High Carbon Steel C45 sheets and plates. Known for its exceptional durability, this grade is a cornerstone for projects that demand resilience and performance. We understand the needs of New Zealand industry, providing material that stands up to the toughest challenges, ensuring your fabrication and engineering work is built on a foundation of quality you can count on.
The composition of C45 steel is engineered for strength, featuring a carbon content that gives it notable hardness and wear resistance. This balance is achieved through careful control of its elements, resulting in a material that responds well to heat treatment. After proper processes, it delivers excellent mechanical properties, including high tensile strength and good toughness. This makes it a versatile choice where a robust material is essential, capable of withstanding significant stress and impact without compromising its structural integrity.
