Stainless Steel 446 Tubing is a ferritic stainless steel that doesn’t require heat treatment and boasts impressive resistance to corrosion and oxidation. It typically contains around 23–27% Chromium, a maximum of 0.20% Carbon, 1.50% Manganese, 1.00% Silicon, and minimal amounts of Phosphorus and Sulfur, along with trace elements of Nickel and Molybdenum. Its mechanical properties include a tensile strength of about 485 MPa, yield strength of 275 MPa, and an elongation of roughly 20%. With a Brinell hardness of around 170, this grade is recognized for its excellent scaling resistance at temperatures reaching up to 1100°C, making it perfect for high-heat applications.
