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 resistence with high heat resistence and wear resistence. Superior resistence to cracking when exposed to alternating thermal stress is the new wheel's key characteristic. The critical number of cycles has been raised from 5,800 to 9,000 under extreme cycling loading and 6,000 to 12,000 at the normal level of stress cycling.
