The Stainless Steel 347 Flat Bar is an austenitic chromium-nickel stainless steel that’s stabilized with niobium, boosting its resistance to intergranular corrosion. It typically features 17–19% chromium, 9–13% nickel, and 0.5–1% niobium, along with trace amounts of carbon, manganese, and silicon. On the mechanical side, it boasts excellent tensile strength, yield strength, and hardness, maintaining its structural integrity even at elevated temperatures. With remarkable creep resistance and toughness, it stands up to oxidation and scaling in extreme conditions. These characteristics make it perfect for applications that demand long-term reliability and top-notch performance in challenging environments.

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.
Stainless Steel 347 Flat Bar is widely utilized across various industries due to its outstanding corrosion resistance and high-temperature strength. It’s particularly suited for chemical processing equipment, heat exchangers, furnace components, and boiler parts where durability under stress is essential. Additionally, it’s used in automotive, aerospace, and food processing sectors, as well as in architectural structures that face harsh conditions. Its ability to resist oxidation and scaling ensures a long lifespan in high-temperature settings, while its mechanical properties support heavy-duty structural applications. Engineers and manufacturers trust Stainless Steel 347 Flat Bar for its reliability and performance in demanding situations.
