Thermally treated medium-thick plates are steel plates whose mechanical and physical properties are enhanced through precise heat treatment processes. The heat treatment process involves heating, holding at temperature, and cooling, which are designed to modify the microstructure of the steel, thereby improving its strength, toughness, hardness, and wear resistance. Q235B carbon steel thermally treated medium-thick plate is a medium-thickness carbon steel plate processed through heat treatment and belongs to the low-carbon steel grade specified in the Chinese standard GB/T 700. Due to its good ductility, toughness, and weldability, Q235B steel is widely used in engineering and construction fields. Heat treatment can further enhance the mechanical properties of this steel, such as strength and hardness, while improving its wear resistance and impact resistance.
