SS490 Structural Steel H Beam
SS490 H-beam is a hot rolled structural steel that conforms to JIS G 3101. It is commonly used in various structural applications. SS490 has a higher tensile strength than SS400 steel. Its chemical composition includes up to 0.050% phosphorus and sulfur, as well as iron and minor impurities. Its mechanical properties make it ideal for the manufacture of structural pipes, tubes, bars and various profiles.
