Stainless Steel 347 JIS 10K Flanges

Stainless Steel 347 is a type of austenitic stainless steel that contains columbium and tantalum as stabilising elements. This composition provides the steel with excellent resistance to intergranular corrosion, high-temperature creep, and stress rupture, as well as excellent toughness in corrosive environments such as phosphoric and sulfuric acids. The chemical composition of Stainless Steel 347 JIS 10K flanges typically includes: Carbon (C): 0.08% maximum, Manganese (Mn): 2.00% maximum, Phosphorus (P): 0.045% maximum, Sulfur (S): 0.030% maximum, Silicon (Si): 1.00% maximum, Chromium (Cr): 17-20%, Nickel (Ni): 9-13%, Columbium + Tantalum (Cb + Ta): 10xC minimum, Iron (Fe): Balance. This well-balanced chemical composition gives SS 347 the desired properties for various applications. JIS 10K flanges are commonly used in piping and pressure vessel applications, where their high strength and resistance to corrosion make them a reliable choice.

SS 347 JIS 10K Flanges are used in various industrial applications where strength, resistance to high temperature, and corrosion resistance are required. These flanges are made of alloy 347, which contains chromium, nickel, and other elements that enhance its corrosion resistance and high-temperature stability. The JIS 10K rating indicates that they are designed to handle high pressure and withstand a maximum pressure of 10 kilopascals. The high nickel content in these flanges makes them resistant to stress corrosion cracking and intergranular corrosion, making them ideal for use in harsh chemical environments. Additionally, these flanges are easy to fabricate and can be machined to meet specific requirements, making them a popular choice in petrochemical, chemical processing, and power generation industries.
