Vinit Stainless, one of the top manufacturers and suppliers in Chennai, India, offers premium Stainless Steel 446 Pipes. These pipes are tailor-made for uses requiring superior resistance to high-temperature corrosion and oxidation. Our SS 446 pipes are thoroughly crafted to endure harsh thermal conditions, making them a perfect fit for furnaces, heat exchangers, and other high-temperature industrial operations where reliability and scaling resistance are essential to achieve operational longevity.
Stainless Steel 446 is a ferritic stainless steel with high chromium content, renowned for its outstanding resistance to oxidation and sulfur-containing gases at high temperatures. Its composition is normally 23-27% Chromium with low carbon, supplemented with small amounts of silicon and manganese. Mechanically, it has good strength at high temperatures with tensile strength ranging from 415-550 MPa and yield strength of 275-380 MPa. It is not hardenable and retains structural stability in severe thermal conditions.
