DISC RINGS

Forgings are made by the closed die method as Germany. Subsequent processing consisting of two machining steps and four heat treatment steps are completed in China.The steel manufacturing processes are designed to keep impurities to the lowest.Melting in an Electric Arc Furnace is followed by vacuum degassing. Ingot molds are filled from the bottom with the liquid steel shrouded in argon gas. Exceptionally clean steel ensures high resistance to fatigue, resulting in longer cutter disc life
