Latham Steel, a trusted name in Hamilton, New Zealand, specializes in manufacturing and supplying top-notch NAXTRA 70 Sheets and Plates designed for exceptional structural performance. This high-strength, thermomechanically rolled steel grade boasts impressive toughness, weldability, and dimensional stability, making it perfect for tough construction and engineering projects. With a commitment to strict quality control, Latham Steel delivers plates that feature consistent mechanical properties and precise tolerances, ensuring reliable fabrication. Industries that rely on heavy machinery, transport equipment, cranes, structural frames, and high-load-bearing components count on NAXTRA 70 for its long service life, reduced weight, and enhanced efficiency in challenging operating conditions.
NAXTRA 70 Sheets and Plates are crafted through thermomechanical rolling, resulting in a fine-grained, uniform microstructure. The steel is formulated with controlled amounts of carbon, manganese, niobium, titanium, and vanadium to boost strength, toughness, and weldability. This grade offers a minimum yield strength of 690–700 MPa, along with robust tensile properties and excellent impact resistance. Its low carbon equivalent allows for efficient welding without compromising structural integrity. Additionally, NAXTRA 70 exhibits good cold-forming capabilities and stable performance under high stress, making it an ideal choice for precision fabrication and heavy-duty engineering tasks.
