12Cr1MoV steel plates are widely used in the power industry for manufacturing high-temperature and high-pressure boiler components, such as boiler drums, superheater headers, and steam pipelines, as they exhibit excellent creep resistance and thermal stability at temperatures up to 580°C. In the chemical and petrochemical sectors, they are applied to produce hydrogenation reactors, high-temperature heat exchanger shells, and pressure vessels handling high-temperature media, benefiting from their good high-temperature strength and corrosion resistance to mild industrial atmospheres. They also find applications in the metallurgical industry (for high-temperature furnace shells) and thermal power plant auxiliary equipment (for high-pressure pipeline flanges), ensuring long-term reliable operation in harsh high-temperature and high-pressure industrial scenarios.
