Stainless Steel 446 Tube is ferritic stainless steel tube known for strong resistance to oxidation and scaling at high temperatures. Preston Alloys is a trusted 446 stainless steel tubing suppliers, offering tubes with precision and quality. These tubes are made up of carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, molybdenum, and nitrogen, which give alloy superior properties. SS 446 tube provide reliable mechanical performance with a tensile strength of 485 MPa and a yield strength of 275 MPa. With a density of 7750 kg/m³ and display thermal conductivity at both 100°C and 500°C, ensuring consistent strength and stability across varying conditions.
Stainless Steel 446 Tube performs well at temperatures ranging between 1500°F and 2100°F, making it ideal for thermal processes, although its high-temperature strength is limited. These tubes are used in oil burners, heat exchangers, furnace parts, kiln liners, glass moulds, and stationary soot blowers in steam boilers. UNS S44600 High Pressure Tube is also relied on in industries such as construction, petrochemical, natural gas, and general industrial setups. Known for their high strength, resistance to mechanical stress, pressure, and temperature, these tubes feature good formability and reusability. Choose SS SA213 tube when durability and long service life are critical.
Our SS 446 seamless tube meet ASTM A213, ASME SA269, ASTM A269, and ASTM A249 standards. Sizes range from 1/8″NB to 30″NB to meet different project needs. These tubes are available in seamless, ERW, welded, fabricated, and LSAW forms. Shapes include round, square, rectangular, and hydraulic, with lengths offered in single random, double random, or custom-cut sizes. End finishes such as plain end, beveled end, or threaded options, giving buyers flexibility for installation and application. Many projects use UNS S44600 high pressure tube for safe and efficient performance in both standard and specialized environments.
Each batch of stainless steel 446 tubes go through quality tests to ensure consistent performance and durability. The tubes are packed securely to prevent damage during transport and handling. As a reliable stainless steel 446 tubes stockist, we offer tubes in custom sizes and shapes for specific project needs. Contact us for ASTM A249 TP446 seamless tubes that provide strength, safety, and performance in a variety of applications.
