JIS G 3103 SB 450 is a carbon steel plate used for manufacturing boilers and pressure vessels, primarily applied in the following areas:
Boiler Manufacturing: Due to its excellent high-temperature strength and pressure resistance, SB 450 steel plates are commonly used in the production of pressure components for industrial boilers, such as boiler shells and pipelines.
Pressure Vessels: Suitable for the fabrication of medium and low-pressure vessels, such as storage tanks, heat exchangers, and reactors, particularly in scenarios requiring resistance to specific pressures and temperatures.
Energy Industry: Widely used in pressure components for thermal power plants, petrochemical facilities, and natural gas processing equipment.
Other Industrial Applications: Employed in engineering projects requiring moderate strength and good weldability, such as certain chemical industry equipment or heat treatment devices.
