Product Description
Product introductionShip Plate
Marine steel plates refer to hot-rolled steel plates produced according to the requirements of the Classification Society's construction specifications for the manufacture of hull structures.
Due to the harsh working environment of the ship, the hull is subject to chemical corrosion, electrochemical corrosion and corrosion of marine organisms and microorganisms; The hull bears large wind wave impact and alternating load; The ship shape makes the processing method complex and other factors, so the requirements for hull structure steel are strict. First of all, good toughness is the most critical requirement. In addition, high strength, good corrosion resistance, welding performance, processing and molding performance and surface quality are required. In order to ensure quality and enough toughness, Mn/C of chemical composition is required to be above 2.5, and carbon equivalent is also strictly required, which shall be produced by a steel factory approved by the ship inspection department. Structural steel for hull is classified into general strength structural steel and high strength structural steel according to its minimum yield point. Structural steel for hull is divided into general strength steel and high strength steel, and general strength steel is divided into four grades: A, B, D and E according to quality; High strength steel is divided into two strength grades and three quality grades; AH32,DH32,EH32,AH36,DH36,EH36.
