Rithav Pipes and Tubes stands out as a top manufacturer and supplier of Stainless Steel 446 Tubing, proudly based in Delhi, India. We specialize in high-performance SS 446 tubing that’s built to endure extreme heat and resist corrosion, especially in high-temperature and oxidizing settings. Crafted from top-notch raw materials and utilizing cutting-edge production techniques, our 446 tubing guarantees outstanding durability, dimensional stability, and a long lifespan. Stainless Steel 446 is a ferritic alloy celebrated for its exceptional resistance to oxidation and scaling. At Rithav Pipes and Tubes, we’re dedicated to providing reliable and cost-effective stainless steel tubing solutions, ensuring timely service throughout India.
Stainless Steel 446 Tubing features a high chromium content (23–27%) and low carbon, which gives it remarkable resistance to oxidation, sulfidation, and high-temperature corrosion. As a ferritic stainless steel, it boasts moderate tensile strength (380–580 MPa), yield strength (170–260 MPa), and good thermal conductivity. It maintains its structural integrity and resists scaling even at elevated temperatures of up to 1100°C. While it may not be as weldable as austenitic grades, its ability to withstand thermal fatigue, carburization, and chemical attacks makes it perfect for tough environments where heat and corrosion resistance are essential.
