The manufacturing process of steel balls
JUNDA company produces φ20 to φ 150 forged steel balls ,select high
quality round 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
make our forged steel balls have a better performance in the overall hardness,
surface hardness 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 content in
0.05-1 2.
We can product different size according to customer's request.
