JIS B 2220 flanges are Japanese Industrial Standard pipe flanges used for pressure piping connections. They are typically made from carbon steel (e.g., SS400, S10C), stainless steel (e.g., SUS304, SUS316), or alloy steel, depending on application requirements. Composition varies with material grade but generally includes iron with controlled amounts of carbon, manganese, silicon, chromium, and nickel. Mechanical properties include tensile strength of 400–520 MPa, yield strength of 245 MPa minimum, and elongation of 20% or more. These flanges offer excellent strength, durability, and corrosion resistance for industrial use.
