SGS is the world’s leading inspection, verification, and testing company. By choosing to audit our manufacturing process, we demonstrate our commitment to international standards.

SGS Test Report Forged Grinding Balls: Key Data

The independent laboratory analysis focuses on three critical areas:

  • Chemical Composition: Verification of Chromium (Cr) and Carbon (C) levels to ensure material consistency.
  • Hardness (HRC): Measurement of surface and core hardness to guarantee wear resistance.
  • Impact Toughness: Testing to ensure the balls can withstand high-stress impacts without fracturing.

What Does the SGS Report Verify?

The SGS inspection covers critical parameters that determine the lifespan and efficiency of grinding media. Here is what our latest certification confirms:

  • Chemical Composition: The report verifies the precise ratios of Chromium (Cr), Carbon (C), Manganese (Mn), and other alloys. This consistency is vital for achieving the desired microstructure during heat treatment.
  • Hardness & Wear Resistance: High hardness (measured in HRC) is essential for reducing wear rates. The SGS test confirms that our balls maintain high hardness throughout their cross-section, ensuring long service life.
