Stainless Steel 347 JIS 15K Flanges

Stainless Steel 347 is austenitic stainless steel that contains columbium and tantalum as stabilising elements. These elements help to prevent intergranular corrosion, provide high-temperature creep resistance and stress rupture, and increase toughness in corrosive environments like phosphoric and sulfuric acids. The chemical composition of Stainless Steel 347 JIS 15K flanges typically includes elements such as carbon, manganese, phosphorus, sulfur, silicon, chromium, nickel, columbium and tantalum, and iron. The specific proportions of these elements vary, but they work together to create a well-balanced composition that gives SS 347 its desirable properties. JIS 15K flanges are often used in high-pressure piping and pressure vessel applications due to their strength and resistance to corrosion.

Stainless Steel 347 JIS 15K Flanges are commonly used in industrial applications where high strength, high temperature, and corrosion resistance are required. These flanges are made of alloy 347, which contains chromium, nickel, and other elements that enhance its durability and corrosion resistance. The JIS 15K rating indicates that they are designed to handle high pressure, with a maximum pressure rating of 15 kilopascals. This makes them ideal for use in high-pressure piping systems. The high nickel content in these flanges makes them resistant to stress corrosion cracking and intergranular corrosion, making them suitable for use in harsh chemical environments. In addition, these flanges are easy to fabricate and can be machined to meet specific requirements, making them a popular choice in industries such as petrochemical, chemical processing, and power generation.
