We pride ourselves on delivering top-notch piping solutions tailored for the toughest industrial settings. With a focus on precision manufacturing, rigorous quality control, and compliance with international standards, Mitchell Stainless caters to industries that demand exceptional corrosion resistance and long-lasting reliability. Our Stainless Steel 348 Pipes are specially designed for high-temperature and welded applications. Thanks to our state-of-the-art production facilities, skilled technical team, and a customer-centric approach, we guarantee consistent performance, timely delivery, and customized solutions to meet a variety of project needs across New Zealand and beyond.
Stainless Steel 348 is a unique blend of niobium and tantalum-stabilized austenitic stainless steel, with chromium and nickel as its main alloying elements. This stabilization effectively prevents carbide precipitation during welding and high-temperature use. Typically, these pipes contain about 18% chromium and 10% nickel, providing outstanding resistance to intergranular corrosion. On the mechanical side, they boast impressive tensile strength, ductility, and toughness, even when exposed to elevated temperatures. These pipes maintain their structural integrity under thermal stress, making them ideal for pressure and heat-intensive applications.
