They serve a variety of industries, including chemical processing, power generation, marine, and automotive, focusing on durability, corrosion resistance, and performance at high temperatures. The company is dedicated to timely deliveries, providing technical support, and fostering long-term partnerships, ensuring that their Stainless Steel 446 hollow bars offer consistent reliability even in harsh, high-temperature, and corrosive environments.
These hollow bars are primarily made of iron, featuring a high chromium content, low carbon levels, and trace amounts of nickel and other alloying elements. This unique composition grants them exceptional resistance to oxidation, scaling, and corrosion, especially at elevated temperatures. On the mechanical side, 446 stainless steel boasts impressive tensile strength, excellent hardness, and robust resistance to creep, thermal fatigue, and dimensional changes during thermal cycling. The hollow design not only makes these bars lightweight but also structurally strong, making them perfect for high-temperature and corrosive service environments.
