UltraDur ER8H Deep hardness 265HBW around the wheel tread The world's leading high-speed bike based on the new UltraDur ER8H material in terms of smoothness and mileage was developed together with CRRC. The requirement profile for use in China was demanding: speeds up to 380 km / h, temperature fluctuations from -40 ° C to + 45 ° C, humidity up to 95%, resistance to strong winds, rain, snow and acid rain, sandstorms and salt fog and the like more. The new UltraDur ER8H high-speed wheels meet all these requirements by increasing the hardness to at least 265HBW evenly around the wheel circumference and in the depth down to the wear line. And of course it complies with the demanding material parameters such as strength and impact work in the wheel rim and web as well as the customer's metallographic specifications regarding structure, degree of purity and grain size. The partially contradicting requirements, e.g. for hardness and notch impact, cannot be met without outstanding expertise in the areas of material development and heat treatment. This is where the special competence of the BVV lies. This is one of the reasons why we are considered to be the only ones in the world that demonstrably meet the Chinese requirements. This is also good news for customers all over the world who rely on smoothness and mileage in high-speed traffic.
