steel mill balls

steel mill balls, new material steel mill balls finished size precise cylindrical geometry, with overall high hardness, impact toughness, deformation, anti broken capability is strong, which is widely used in non-ferrous metal processing industry, chemical industry, thermal power industry, cement industry and non metal broken self supporting production industry for global energy saving, energy, environmental protection and make a significant contribution.

Product features

1, the broken rate of less than 0.5%, crush resistance is 10 times more than the general cast ball.

2, the impact toughness of high impact toughness is greater than 18J/cm2, 8 meters above the 20 thousand falling ball experiment.

3, the overall high hardness: the surface hardness of 58-67HRC, the volume of hardness of 57-64HRC, and the average hardness gradient distribution.

4, do not always ball deformation: the deformation, failure resistance.

5, compact structure, high cost, obvious cost savings.
