Introduction JIS G 3118 specifies hot-rolled carbon steel plates used mainly for pressure vessels operating at intermediate and moderate temperatures. These plates are designed to meet specified requirements for strength, weldability, chemical composition, and mechanical properties. JIS G 3118:2024 is the current edition of this standard. The plates are used in pressure-containing equipment where material quality and compliance with the specified operating conditions are essential. Ladhani Metal Corporation is a manufacturer, supplier, and exporter of carbon steel plates for industrial and pressure vessel applications. Material can be supplied according to required grades, dimensions, and delivery conditions, with mill test certificates and quality inspection as applicable. Available Grades SGV410 | SGV450 | SGV480 Forms of Supply Hot-rolled carbon steel plates Pressure vessel steel plates Cut-to-size plates Plates supplied in required thicknesses, widths, and lengths Material Type Carbon Steel (CS) | Pressure Vessel Steel | Hot-Rolled Steel Plates Chemical Composition The chemical composition of JIS G 3118 plates depends on the grade and applicable thickness. The standard specifies limits for carbon, silicon, manganese, phosphorus, and sulfur, along with other requirements where applicable. Example Grade: SGV410 Carbon (C): As per standard requirements Silicon (Si): As per standard requirements Manganese (Mn): As per standard requirements Phosphorus (P): As per standard requirements Sulfur (S): As per standard requirements Mechanical Properties The mechanical properties of JIS G 3118 plates include tensile strength, yield point or proof stress, and elongation. Required values depend on the grade and plate thickness. SGV410: Nominal tensile strength class of 410 MPa SGV450: Nominal tensile strength class of 450 MPa SGV480: Nominal tensile strength class of 480 MPa Final mechanical property requirements must be confirmed against the applicable standard and material test certificate. Surface Finish JIS G 3118 carbon steel plates are generally supplied with a hot-rolled surface finish. Surface quality and permissible imperfections are subject to the applicable standard and purchase requirements. Delivery Condition Plates are supplied in the delivery and heat-treatment condition specified for the selected grade, thickness, and order requirements. Any required heat treatment or additional testing should be confirmed when placing the order. Key Features Suitable for specified pressure vessel applications Controlled chemical composition and mechanical properties Suitable for welding and fabrication using appropriate procedures Available in different grades and plate dimensions Material documentation and inspection according to order requirements Applications Pressure vessels and process vessels Industrial storage tanks Chemical and petrochemical processing equipment Pressure-containing equipment for moderate-temperature service Industrial plant and process equipment Power generation equipment where the selected grade is suitable Heavy-duty fabricated pressure structures Conclusion JIS G 3118 carbon steel plates are used in pressure vessel manufacturing and industrial equipment that require specified strength, weldability, and material quality.
