This are common mild steel/carbon steel plate for structural, manufacturing plant, machinery, mining equipment , excavators, loader, bulldozers, crane, mining hydraulic supports, construction, power plant, sugar mill, palm oil mill, oil and gas, port equipments, fans, drilling rigs, power shovel and other structural parts. Heat analysis shall be used to determine the required chemical composition for carbon. Manganese, phosphorus, sulfur, silicon, and copper. Tensile strength, yield strength, and elongation shall be evaluated using tension test.
S275JR and its related series (S275J0, S275J2, S235JR, S235J0, S235J2) are very versatile common mild steel/carbon steel plate for multiple structural applications e.g. manufacturing plant, machinery, mining equipment and vehicles, excavators, loader, bulldozers, crane, mining hydraulic supports, construction, power plant, sugar mill, palm oil mill, oil and gas, port equipments, fans, drilling rigs, power shovel and other structural parts. Heat analysis shall be used to determine the required chemical composition for carbon. Manganese, phosphorus, sulfur, silicon, and copper. Tensile strength, yield strength, and elongation shall be evaluated using tension test.
