Medium thick plate is a commonly used steel product, with main features including high strength, good toughness, and weldability. There are various types of medium thick plates, including carbon steel plates, low-alloy steel plates, and stainless steel plates. They are usually manufactured through hot rolling processes, which can ensure the steel plates feature uniform thickness and a smooth surface. Medium thick plates can also undergo heat treatment and surface treatment according to different application requirements to improve their corrosion resistance and wear resistance. Medium thick carbon steel plates are made from steel with moderate carbon content, and their thickness usually ranges between 4mm to 60mm. This type of steel plate, because of its excellent mechanical properties and cost-effectiveness, is widely used in various industrial fields. They are mainly used for the manufacture of construction, bridges, ships, vehicles, and heavy machinery.
