Some Features of Material Usage in the Chinese EQ140 Truck 811423

The newly mass-produced EQ 140 truck is designed for difficult service conditions existing in China. The policy of material selection is to ensure good quality of the truck and to make full use of resources rich in the country. In order to beneficially exploit the full value of cast iron, RE-Mg treated irons are employed. Wide application of high strength steels makes the truck more durable and lighter. For good hardenability, a series of boron steels is developed to save large amount of precious alloys. The success of the truck proves that the policy of selection and development of materials is well-based both technically and economically.
