The primary alloying element in Stainless Steel 347 is niobium (Nb), which stabilizes the material against carbide precipitation during welding and high-temperature exposure. This enhances its resistance to intergranular corrosion and improves its overall high-temperature strength.
Stainless Steel 347 is most suitable for applications in the temperature range of 800°C to 1500°F (427°C to 815°C). This range allows it to maintain its strength, corrosion resistance, and stability, particularly in high-temperature environments like furnaces.
Typical dimensions of a Stainless Steel 347 flat bar range from 0.25 inches (6 mm) to 6 inches (150 mm) in thickness and 1 inch (25 mm) to 12 inches (300 mm) in width. Custom sizes are also available.
The Stainless Steel 347 Flat Bar is commonly utilized in scenarios that demand high strength along with heat and corrosion resistance. Typical applications include petrochemical equipment, heat exchangers, boilers, pressure vessels, and exhaust manifolds. It’s also frequently found in power generation plants, refineries, and chemical processing facilities that experience continuous thermal cycling. In the realms of fabrication and construction, these flat bars serve as structural supports, frames, and components where long-lasting durability and dependable performance are crucial.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
