JFE-EH360LE Wear Resistance Steel Sheet

 

The requirements placed on steel plates for construc­tion and industrial machinery use have diversified in recent years, as exemplified by low temperature tough­ness to enable use in cold districts and improved weld­ability by lowering the preheating temperature for weld­ing. 


To meet these requirements, JFE Steel has developed new abrasion resistant steel plates, “JFE-EH360LE/EH500LE,” and a new high strength steel plate, “JFE-HITEN780LE,” with good weldability and low tempera­ture toughness guaranteed at -40°C. In the developed steel plates, high hardness or high strength was achieved by selecting the optimum C content and hardenability (DI), while reducing the carbon equivalent (Ceq) in con­sideration of weldability. 


Low temperature toughness at -40°C was improved in the developed steel plates by applying microalloying and thermo-mechanical control process (TMCP)/controlled heat treatment process tech­nologies to refine prior austenite grains.


JFE produces 11 grades of abrasion-resistant steel plate. This grade is made with the emphasis on microalloying technology, controlled heat treatment, and high toughness. This datasheet provides information on composition, hardness, tensile properties, and bend strength as well as fracture toughness. It also includes information on low temperature performance as well as forming, machining, and joining.
