In the Houston area, distributors and steel service centers provide stainless steel 446 angle sections that are perfect for high-temperature applications. These L-profiles, which typically range from 20×20 mm to 100×100 mm and can be up to 10 mm thick, are ready to ship in both hot-rolled and cold-rolled finishes. Suppliers are equipped to cut them to length, bundle, and deliver them swiftly throughout Greater Houston, catering to industries like petrochemical, power generation, and industrial furnace fabrication. Many of these products meet ASTM A240 standards and come with full traceability. They also offer services like precision cutting, machining, and welding preparation to fulfill the demands of high-temperature structural applications.
The 446 alloy is a ferritic stainless steel that contains about 23–27% chromium, no more than 0.20% carbon, up to 1.5% manganese, up to 1% silicon, and up to 0.75% nickel, along with trace amounts of phosphorus and sulfur. It has a density of around 7.8 g/cm³, a melting range of approximately 1425–1510 °C, and a Young’s modulus close to 200 GPa. When annealed, its tensile strength is roughly between 485–585 MPa, yield strength is around 275–485 MPa, and it has an elongation of about 20%, with a Brinell hardness of approximately 185–201 HB. It can resist oxidation up to about 1100 °C, but it may become brittle at certain mid-range temperatures.

The stainless steel 446 angle provides excellent benefits, especially in high-temperature environments. It provides exceptional resistance to oxidation, corrosion and scaling even at temperatures up to 1100 degrees Celsius. The high chromium content increases strength and durability, making it ideal for applications such as heat exchangers, industrial furnaces, heating appliances, etc. It exhibits excellent resistance to sulfur gases and dried water, and maintains durability under harsh conditions. In addition, its robust mechanical properties and weldability make it applicable to a variety of construction and industrial applications, providing reliable performance and long service life.
Stainless steel 446 angle sections are particularly well-suited for high-temperature and corrosive environments. They find common use in components for furnaces and kilns, including combustion chambers, muffles, recuperators, muffler parts, stack dampers, boiler baffles, and soot blowers, where maintaining oxidation resistance up to 2000 °F is crucial. In the petrochemical and power sectors, they are essential for heat exchangers, spouts, and splicing for molten metal, as well as refractory applications.
