Typically, JIS B2220 20K Flanges are made from carbon steel grades such as SS400 or similar, featuring a carbon content of about 0.17–0.21%, manganese levels of 0.30–0.70%, along with trace amounts of sulfur and phosphorus. These flanges boast a tensile strength between 400 to 510 MPa and a yield strength of around 245 MPa. They are known for their good toughness, weldability, and moderate resistance to corrosion. The 20K rating signifies their suitability for medium-pressure systems up to 20 kg/cm², making them robust enough for pipelines that operate under moderate mechanical stress and temperature conditions.
