Vipul Pipes and Tubes has made a name for itself as a reliable partner for stainless steel tubing solutions across the country by emphasising accuracy, dependability, and prompt delivery.
Stainless Steel 439 Tubing is a ferritic stainless steel alloy that has a low carbon content (≤0.03%) and a chromium content of 17–19%. Titanium has been added to improve stability and resistance to intergranular corrosion. Particularly in conditions with high temperatures, the alloy provides good oxidation resistance and formability. Tensile strength ranges from 415 to 620 MPa, yield strength is approximately 260 MPa, and elongation is roughly 25%, according to mechanical properties. Because of its exceptional structural integrity during welding and fabrication, SS 439 tubing is appropriate for industrial and automotive applications requiring moderate resistance to corrosion and thermal stability.
