JFE-EH500LE wear resistance steel


JFE Steel has succeeded in developing super abrasion-resistant steel plate EVERHARD-SP with higher abrasion-resistance than that of the Brinell hardness 500 grade. In addition, JFE Steel has developed EVERHARD-C400LE, EVERHARD-C450LE and EVERHARD-C500LE, which are produced by the leading-edge manufacturing process and guarantees low temperature toughness at −40°C (−40°F). All these products have earned an outstanding reputation with customers.

 
EVERHARD is available in 6 grades of the Standard Series and 3 grades of the High Toughness Series, which guarantees low temperature toughness of −40°C (−40°F) and also considers internal hardness. With the addition of the super abrasion-resistant grade EVERHARD-SP to these two series, the EVERHARD product line includes a total of 10 grades. The target value (average value) of Brinell surface hardness is used in the numerical figures in the grade names so that customers can easily understand the properties of each grade. By specifying narrow ranges of Brinell hardness, consideration is given to reducing variations in formability in customers’ manufacturing processes.
 
Standard Series In the Standard Series, priority is placed on the hardness of the steel with minimum addition of alloying elements to the chemical composition. The lineup now includes two new products; EVERHARD-C340, which focuses on formability in heavy-gauge products with thicknesses exceeding 100 mm, and EVERHARD-C550, EVERHARD-C600, which is designed especially for abrasion resistance in simpleshaped parts such as liners. High Toughness Series By applying a leading-edge manufacturing process, JFE Steel succeeded in developing an abrasion-resistant steel that guarantees low temperature toughness at −40°C (−40°F) in the product line up to Brinell 500 grade. These are the optimum products for applications where higher toughness or internal hardness is required, particularly for use in cold environment or in the cases with heavy impacts, etc. These materials can be used with confidence, as they also provide high weld cracking resistance performance.
 
Super Abrasion-Resistant Steel Plates (EVERHARD-EH500LE) Longer life of abrasion-resistant steel plates is constantly demanded by customers from the viewpoint of reducing running costs. However, it had been difficult to manufacture steel materials with abrasion resistance exceeding Brinell hardness 500 grade by conventional technologies due to problems with weldability and formability. EVERHARDSP, developed by JFE Steel, provides higher abrasion resistance than that of the Brinell hardness 500 grade without sacrificing weldability and formability.
