From Hamilton’s industrial heart, Latham Steel has built a reputation as a reliable local partner for quality steel components. We take pride in supplying robust Carbon Steel A105 Forged Fittings, trusted by industries across New Zealand. Sourced to meet rigorous international standards, these fittings are the backbone of dependable piping systems. We understand that your projects require durability you can count on, and our A105 range is selected with that exacting standard in mind, ensuring performance and longevity for the demanding conditions you face every day.
The strength of A105 fittings comes from their specific makeup. Primarily composed of carbon, manganese, and silicon, this material is forged, a process that enhances its inherent strength. This results in excellent tensile strength and good yield properties, allowing it to handle high pressure effectively. While not inherently corrosion-resistant, its toughness makes it ideal for a wide range of service conditions, particularly where mechanical stress is a primary concern rather than chemical attack.
