Characteristics: The unique domestic advanced technology of vacuum smelting combine with rolling and heat treatment
Small and closely crystalline grain without any defect
Strong fatigue resistance with high heat resistance and wear resistance
Superior resistance to cracking when exposed to altemating thermal stress is the new wheel's key characteristic. The critical number of cycles has been raised from 5800 to 9000 under extreme cycling loading, and from 6000 to 12000 at the normal level of stress cycling.
