Blundell Pipes and Tubes, a well-respected manufacturer and supplier based in Hamilton, New Zealand, offers top-notch Stainless Steel 446 Tubing that’s built to last in the toughest high-temperature and corrosive settings. Crafted with cutting-edge techniques, this tubing boasts impressive resistance to oxidation, scaling, and sulfur gases. It’s designed to maintain structural integrity and a long lifespan, even when faced with constant thermal stress. With meticulous attention to dimensional accuracy and quality, Blundell Pipes and Tubes delivers reliable tubing solutions that are perfect for critical industrial, thermal processing, and chemical applications.
This tubing is made from a high-chromium ferritic stainless steel, containing around 23–27% chromium, which gives it remarkable resistance to oxidation and thermal wear. It features moderate tensile and yield strength, along with strong resistance to carburization and sulfidation, ensuring dependable creep strength at high temperatures. The ferritic structure not only enhances dimensional stability but also minimizes thermal expansion, guaranteeing consistent mechanical performance. These characteristics make the tubing an excellent choice for extended use in harsh, high-heat industrial environments.
