IRAETA offers traditional forged ball products to customers whose diameter requirement is more than 125 mm or who have special requirements. Forged balls are made from our custom grade raw materials. IRAETA has over five years of manufacturing expertise of forged balls. We ensure that the ball size is uniform and that they have a smooth surface. We ensure that each ball is subject to strict quenching and tempering heat treatment regimes. We ensure uniformity in outer hardness and inner toughness, which gives excellent impact resistance, toughness and durability to the product. Results achieved after inspection indicate that the spherical hardness and volume hardness of the grinding ball meet the standards required in HRC58-65, and that the impact toughness is greater than 15 j/cm2. The drop test is carried out more than 10000 times, while the actual crushing rate is lower than 0.5%.
