Based in Houston, Texas, George Metals is a leading producer and supplier of premium stainless steel goods, providing customized steel solutions for a variety of industries. With decades of experience, we are experts in manufacturing stainless steel 446 flat bars, which are renowned for their remarkable oxidation resistance, thermal stability, and corrosive stability at high temperatures. Strict quality standards are followed during the manufacturing process to guarantee high performance, dimensional accuracy, and dependability. Globally reputable, George Metals is dedicated to providing robust flat bars that satisfy the most exacting specifications in industries like industrial heating systems, petrochemicals, and power generation.
The main constituents of Stainless Steel 446, a ferritic stainless steel alloy, are 23–27% chromium, 0.2–1.0% silicon, and trace amounts of carbon, iron, and manganese. In high-temperature settings, this composition offers exceptional resistance to oxidation, scaling, and thermal fatigue. Mechanical characteristics include an elongation of 20–30%, a yield strength of 250–450 MPa, and a tensile strength of 480–620 MPa. 446 is perfect for thermal processing, chemical exposure, and mechanically stressed applications in operations involving elevated temperatures because of its low rate of thermal expansion and high structural integrity under heat.

Stainless Steel 446 Flat Bar is primarily used in high-temperature and highly corrosive environments, such as industrial furnaces, heat exchangers, thermal oxidizers, and marine applications, due to its exceptional resistance to oxidation, scaling, and chloride stress corrosion.
Stainless Steel 446 Flat Bar contains approximately 23-27% chromium, 0.2% carbon, up to 1.5% manganese, 1.0% silicon, 0.04% sulfur, and trace amounts of nickel, phosphorus, and molybdenum, offering excellent oxidation and corrosion resistance in extreme environments.
Yes, Stainless Steel 446 Flat Bar is highly suitable for high-temperature applications due to its excellent oxidation resistance and ability to withstand temperatures up to 1100°C (2012°F), making it ideal for furnace components, heat exchangers, and thermal oxidizers.
High-temperature, oxidation-prone, and corrosive environments are common uses for SS 446 Flat Bars. When oxidation resistance and dimensional stability are crucial, they are frequently used in boilers, heat exchangers, chimneys, furnace components, and thermal shields. The alloy is appropriate for the petrochemical, power generation, and aerospace industries due to its performance under harsh conditions. Additionally, incinerators, automobile exhaust systems, and chemical processing equipment use it. Critical infrastructure exposed to extreme heat and corrosive media can benefit greatly from the long-term durability that SS 446 flat bars offer due to their high tolerance to thermal cycling and corrosive gases.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
