At Adinox Overseas, we specialize in manufacturing and supplying high-performance Stainless Steel 347 Sheets that are trusted across a wide range of industrial sectors. Recognized for their excellent resistance to intergranular corrosion and superior mechanical strength, our SS 347 sheets are designed to deliver outstanding performance in extreme operating conditions. This austenitic stainless steel is stabilized with columbium (niobium), which enhances its resistance to chromium carbide precipitation, especially in applications involving continuous and intermittent heating up to 870°C.
One of the key benefits of SS 347 Sheet is its exceptional performance in environments exposed to high thermal gradients. The niobium content in 347 stainless steel prevents the formation of chromium carbides, which could otherwise lead to intergranular corrosion. As a result, Stainless Steel 347 is an ideal choice for applications that require welding or involve frequent thermal cycling. Adinox Overseas ensures that each sheet undergoes strict quality control processes to meet or exceed the standards outlined in ASTM A240.
Our Stainless Steel 347 Sheets are manufactured according to international quality standards, primarily following ASTM A240 specifications and are categorized under UNS S34700. These sheets are widely utilized in industries such as chemical processing, oil & gas, power generation, and heat exchangers, where resistance to high temperature oxidation and stress corrosion cracking is essential.
We provide Stainless Steel 347 Sheets in various surface finishes such as No.1, 2B, BA, and mirror polish depending on customer requirements. These sheets are available in a variety of thicknesses and dimensions, which can be customized as per project specifications. Whether you are working on architectural components or high-temperature process equipment, our 347 stainless steel sheets ensure unmatched reliability and longevity.
