Introduction to EH32 steel plate
1. Introduction to EH32 steel plate:
EH32 steel plate is a kind of marine structural steel plate, which is usually used to manufacture various structural components of ships and offshore engineering. It has good weldability, plasticity and impact toughness, and is suitable for use under low temperature conditions. EH32 steel plate has higher strength and belongs to the category of high-strength steel plate. EH32 steel plate implementation standard: implement GB/T18979 standard.
EH32 is a special steel plate for ships and ocean engineering. EH32 steel plate can be certified by nine classification societies including ABS, French BV, British LR, German GL, Norwegian DNV, Italian RINA, Japanese NK, Chinese CCS, and Korean KR.
Marine steel plates refer to hot-rolled steel plates used to manufacture ship hull structures produced in accordance with the requirements of classification society construction specifications. Mainly used for manufacturing hulls, decks, etc. of ocean-going, coastal and inland waterway shipping ships. The working environment of ships is harsh. The hull shell has to withstand the chemical corrosion, electrochemical corrosion of seawater, and the corrosion of marine organisms and microorganisms. It also has to withstand the impact of large wind and waves and alternating loads. In addition, the ship's processing and molding are complex and other reasons. Therefore, There are strict requirements for steel used in hull structures. Good toughness is the most critical requirement. In addition, it must have high strength, good corrosion resistance, welding performance, processing and forming performance and surface quality. Its Mn/C ratio should be above 2.5, it also has strict requirements on carbon equivalent, and it should be produced by a steel factory approved by the ship inspection department. Steel for hull structures is divided into two types: general strength steel and high strength steel. The quality of general strength steel is divided into 4 grades A, B, D, and E; high strength steel is divided into two strength levels and 3 quality grades: AH32 , DH32, EH32, AH36, DH36, EH36.
