Rashid Metals is dedicated to supporting sectors like petrochemical, construction, engineering, and power generation with trustworthy stainless steel solutions tailored for demanding industrial needs.
Stainless Steel 347 Flat Bars are stabilized austenitic stainless steel alloys primarily made up of chromium, nickel, and niobium. This unique blend enhances resistance to intergranular corrosion and prevents carbide precipitation during exposure to high temperatures. The alloy is known for its high tensile and yield strength, good hardness, and excellent toughness across a range of temperatures. Its mechanical properties remain stable even under prolonged heat, making it a great choice for applications that experience frequent thermal cycling. Additionally, Stainless Steel 347 offers reliable formability and oxidation resistance, ensuring it performs well in tough 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.
These Stainless Steel 347 Flat Bars are widely utilized in industries that demand exceptional heat resistance, corrosion protection, and mechanical strength. They are perfect for furnace components, boiler parts, exhaust systems, and high-temperature processing equipment. In the petrochemical and refinery sectors, you’ll often find these flat bars in heat exchangers, reactor vessels, catalytic cracking units, and piping systems that are subjected to elevated temperatures. They also play a vital role in power generation plants, food-grade equipment, chemical processing machinery, and structural frameworks. Their flat design not only provides excellent load-bearing capacity but also makes fabrication a breeze.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
