Jinan Haoyang Casting and Forging has been dedicated to the research and production of wear-resistant steel balls for 20+ years. The 45# forged grinding steel ball is hot‑forged from solid round steel with complete quenching & tempering heat‑treatment. The 45# forged grinding steel ball delivers stable medium‑impact performance with surface hardness HRC48‑55. The 45# forged grinding steel ball is widely applied for cement raw mill, clinker mill and sand‑making grinding operations. We supply the 45# forged grinding steel ball directly from our factory in Shandong, China. Batch chemical composition test reports and hardness inspection reports are available for every batch of the 45# forged grinding steel ball.
45# Forged Grinding Steel Ball Φ50mm
Product Overview
The 45# forged grinding steel ball is specially developed for medium‑load grinding conditions inside cement plants and sand‑making industries. The stable spherical structure of the 45# forged grinding steel ball effectively reduces wear loss during continuous grinding work. Operators can reduce the frequency of adding new grinding media, and the 45# forged grinding steel ball helps plant owners cut comprehensive operation cost. All production of the 45# forged grinding steel ball complies with YB/T 091‑2019 Chinese industry standard for grinding balls.
