Heat-treated wide and heavy steel plates are steel plates processed through special heat treatment techniques, primarily used in applications requiring high strength and wear resistance, such as heavy machinery, construction structures, shipbuilding, and pressure vessels. These steel plates typically have a thickness exceeding 60 mm and widths reaching several meters, making them suitable for the fabrication of large structural components. Carbon steel wide and heavy plates, after heat treatment, exhibit improved strength, toughness, and wear resistance, making them suitable for manufacturing heavy machinery, automotive components, and construction equipment. Q235B carbon steel heat-treated wide and thick plates are low-carbon structural steel plates processed through specific heat treatment techniques. This type of steel is known for its excellent ductility, toughness, and weldability. Through heat treatment processes such as normalizing, quenching, and tempering, its mechanical properties and wear resistance can be significantly enhanced.
