Grinding Steel Balls

Our product advantages：
1.Solid Forged Structure & Superior Impact Resistance.
 One-piece hot forged solid structure without casting defects. Resist heavy continuous impact inside mills, low breakage rate, ideal for high-impact SAG milling conditions.
2.Dense Metallurgical Structure, Zero Inner Porosity.
Forging process creates compact internal metal structure with no pores or shrinkage cavities. Lower attrition loss and longer service life, reducing mill downtime for ball refilling.
3.Hardened Surface with Outstanding Wear Resistance .
Professionally heat-treated, surface hardness HRC58–63. Low specific consumption when grinding ores, cutting clients' total operational cost.
4.Precise Sphericity & Stable Dimensions.
Calibrated diameter with good roundness and tight tolerance. Perfect spherical shape ensures stable grinding efficiency and reliable media gradation.

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.

Our main products include forged grinding steel balls, hot-rolled grinding balls, high-, medium-, and low-chromium cast grinding balls,grinding cylpebs and grinding rods. Our products are manufactured under strict quality control to ensure excellent hardness, toughness, wear resistance, and impact resistance, meeting the demanding requirements of modern grinding applications.
