High Tensile Plates
High Tensile Strength Steel Plates for Civil Engineering and Industrial Machinery
Champak Industry- high tensile plate manufacturers, high tensile steel plates, tensile steel plates manufacturer, industrial steel plates supplier, high tensile brass plates, industrial machinery equipment suppliers, industrial machinery suppliers, industrial machinery wholesale, high strength steel plate. 590S/690S are economical to use and have good weldability with high toughness, because they are produced by controlled rolling or TMCP and optimized chemical composition. They are, therefore, suitable for civil engineering and industrial machinery, even in cold regions.
780S/980S quenched and tempered steel plates come in thicknesses of up to 50 mm with alloying elements reduced to minimum amounts to provide good weldability and high economy. They are thus suited for use in civil engineering and industrial machinery.
780LE is manufactured using JFE's leading technologies including controlled rolling and micro-alloying in low levels, consequently, providing high weldability and high toughness in low temperature(-40oC) regions. |
