SS540 is a high-quality carbon structural steel, available Q420B alternative. Foreign standards often sort them out according to tensile strength of structural steel, such as SS540 (Japan is such a marked), of which 490 indicates that the minimum value of 540 Mpa sigma b ultra high strength steel is refers to the sigma b of 1373 Mpa or steel
Standard: JIS G3101
Dimension range : 1.8mm -580mm x 1000mm-4000mm x 1000mm-18000mm
