Latham Steel, proudly operating from the industrial heart of Hamilton, New Zealand, is your trusted partner for high-performance piping components. We specialise in supplying robust Carbon Steel WPHY 70 Pipe Fittings, engineered to meet the demanding challenges of modern industrial systems. Our commitment is to provide local and international clients with reliable, high-quality solutions that ensure integrity and longevity in critical applications, backed by our deep understanding of the pressures faced by industries today.
The strength of WPHY 70 fittings comes from their specific chemical composition, which includes precise levels of carbon, manganese, and other micro-alloys. This formulation is carefully balanced to produce exceptional mechanical properties, most notably a minimum yield strength of 70 ksi. This high strength is combined with good ductility and notch toughness, making these fittings capable of withstanding extreme pressures, heavy loads, and low-temperature environments without compromising their structural integrity.
