From the industrial heart of Hamilton, New Zealand, Latham Steel has built a reputation as a trusted partner in high-performance materials. We proudly supply Carbon Steel A333 GR 7 Tubing, a product engineered for reliability in the most demanding environments. As a local manufacturer and supplier, our focus is on providing seamless access to this critical-grade steel, backed by the expertise and service that projects in our region and beyond can depend on.
The strength of A333 GR 7 lies in its carefully balanced composition and properties. The addition of nickel, typically between 2.0% and 3.0%, gives this steel its defining characteristic: excellent toughness at low temperatures. Alongside its carbon and manganese content, this nickel alloying allows the tubing to maintain its integrity and resist impact, preventing brittleness even when conditions drop well below freezing, making it a dependable choice.
