From the heart of Hamilton, Neesham Flanges proudly stands as a trusted source for industrial piping solutions. We understand that the integrity of your system hinges on the quality of its components, which is why our Stainless Steel 348 Flanges are manufactured to the highest standards.

Stainless Steel 348 is carefully formulated for stability, featuring a composition that includes chromium and nickel for excellent corrosion resistance. Its key characteristic is the addition of columbium, which is balanced with tantalum, giving these flanges exceptional strength at high temperatures. This specific makeup prevents harmful precipitation, allowing the material to maintain its toughness and mechanical properties, such as strong tensile strength and good ductility, even under the sustained heat and pressure often found in critical industrial settings.
