JUNDA company produces p 20 to p 150 forged steel balls ,select high qualityround steel, low-carbon alloy,high manganese steel, high carbon and high manganese alloy steel as raw material produced by air hammer forging process.We select high-quality round steel as raw materials, and adopts advanced equipment,unique heat treatment process and strict quality control system to makeour forged steel balls have a better performance in the overall hardness, surfacehardness up to 58-65HRC, volume hardness up to 56-64HRC.
The hardness distribution is uniform, the impact toughness value is 12J/cm2,and the crushing rate is far less than 1%.Forged steel ball chemical composition: carbon content in 0.4-0.85, manganese content in 0.5-1.2, chromium contentin 0.05-1.2.
We can product different size according to customer's request.
