Of course, it also complies with the demanding material characteristics such as strength and notch impact energy in the wheel flange and fillet as well as the customer\u2019s metallographic specifications regarding microstructure, degree of purity and grain size.<\/p>\n The partially contradictory requirements, e.g. hardness and notch impact, cannot be met without outstanding expertise in the areas of material development and heat treatment. These represent the core competencies of BVV.\u00a0 This is one of the reasons why we are the only ones in the world that have proven the ability to meet Chinese requirements.<\/p>\n Good news for customers around the world who are looking for smooth running and good mileage during high-speed transportation!<\/p>\n Our offer: Individual wheelsets, wheels and wheelset axles according to your needs.
