Ojas Pipes and Tubes, located in Kolkata, India, has earned a solid reputation as a manufacturer and supplier of Stainless Steel 439 Pipes. They provide high-performance solutions designed for various sectors, including industrial, automotive, and architectural applications. SS 439 is a ferritic stainless steel known for its outstanding corrosion resistance, especially in oxidizing environments, and its excellent weldability. Ojas employs cutting-edge production methods and rigorous quality control to deliver reliable, durable, and cost-effective piping solutions that adhere to global standards. With a commitment to timely delivery and customer satisfaction, Ojas Pipes and Tubes has established a strong presence across India and beyond.
Stainless Steel 439 Pipes are primarily ferritic stainless steels, containing 17.0–19.0% chromium, with titanium (0.10–0.50%) added for stabilization. The carbon content is kept low (≤0.03%) to boost corrosion resistance and weldability. These pipes boast a tensile strength ranging from 415 to 620 MPa, a yield strength of about 240 MPa, and an elongation of roughly 20–30%, striking a great balance between strength and ductility. They also show remarkable resistance to stress corrosion cracking and oxidation, along with enhanced formability and performance under thermal cycling, making them perfect for high-heat and mildly corrosive environments.
