Introduction JIS G 3120 specifies quenched and tempered manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates for nuclear reactors and other pressure vessels. These plates are designed for applications requiring high strength, toughness, and reliable performance under demanding pressure and temperature conditions. The standard specifies requirements for chemical composition, mechanical properties, heat treatment, dimensions, testing, and inspection. Ladhani Metal Corporation is a manufacturer, supplier, and exporter of alloy steel plates for pressure vessel and industrial applications. Material can be supplied according to customer requirements, with mill test certificates and quality inspection as applicable. Available Grades SQV1A | SQV1B | SQV2A | SQV2B | SQV3A | SQV3B Material Type Alloy Steel (AS) | Manganese-Molybdenum Steel | Manganese-Molybdenum-Nickel Steel | Pressure Vessel Steel Surface Finish JIS G 3120 plates are supplied with a hot-rolled surface finish and are subjected to applicable requirements for appearance, dimensions, and permissible surface imperfections. Delivery Condition Plates are generally supplied in the quenched and tempered condition. Other specified heat-treatment arrangements, including stress-relieving requirements, depend on the applicable standard provisions and purchaser agreement. Key Features High strength and toughness Controlled alloy composition Quenched and tempered delivery condition Suitable for demanding pressure vessel applications Specified impact testing and mechanical property requirements Inspection documentation available according to order requirements Applications Nuclear reactor pressure vessels Industrial pressure vessels High-pressure process equipment Chemical and petrochemical plants Power generation equipment Heavy-duty pressure-containing structures Industrial equipment requiring specified strength and toughness Conclusion JIS G 3120 alloy steel plates are used in nuclear reactors and other pressure vessels where strength, toughness, and controlled heat treatment are essential. Grade selection should be based on the design code, operating conditions, plate thickness, and applicable material requirements.
