For over a generation, Latham Steel has been a cornerstone of Hamilton’s industrial landscape, building a reputation for reliability and precision. We take pride in supplying robust solutions for the most demanding projects across New Zealand, and our alloy steel WP5 pipe fittings are a testament to that commitment. These components are forged to withstand extreme pressures and temperatures, offering our clients in critical sectors the durability and performance they require, backed by our local expertise and dedicated service.
The strength of WP5 alloy steel stems from its carefully balanced composition, primarily chromium and molybdenum, which grants it exceptional resistance to heat and corrosion. This metallurgical recipe translates into outstanding mechanical properties, including high tensile strength and excellent creep resistance. Essentially, this means the fittings maintain their integrity and dimensional stability even when subjected to continuous stress under intense heat, preventing deformation and ensuring a long, reliable service life in challenging environments.

We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
You’ll find these WP5 fittings hard at work in sectors where failure is not an option. They are essential in power generation plants, managing superheated steam, and are equally vital in petroleum refineries and chemical processing units, handling corrosive and high-temperature fluids. Their reliability also makes them a preferred choice for high-pressure piping systems in various industrial settings, providing a secure and long-lasting connection that ensures operational safety and efficiency for years to come.
Latham Steel is a leading manufacturer, supplier and exporter of high-quality Carbon Steel, Alloy Steel, Mild Steel and Galvanized Steel products. Our extensive product range includes Pipes, Tubes, Flanges, Pipe Fittings, Forged Fittings, Sheets and Plates, catering to various industries in Hamilton, New Zealand.
