According to DSTU 8538:2015<\/a>, grinding balls 50 HRC after heat treatment should be consistent with the standards shown in table 2 (DSTU 8538:2015<\/a>), for example, for grinding balls with a nominal diameter of 120 mm, this is at least 50 HRC \/ 477 HB on the surface. Please note that information about the upper rate is not specified.<\/p>\n

\"\"<\/p>\n

The main standards for measuring steel grinding balls 50 HRC, according to the control methods prescribed in DSTU 8538:2015<\/a>, is to determine only the hardness on the surface on two diametrically opposite sites.<\/p>\n

Thus, when production and supply of grinding balls 50 HRC, the testing Energosteel\u2019s laboratory takes measurements only on the balls surface in accordance with the DSTU 8538:2015<\/a> standards. However, if the surface of produced grinding balls exceeds the minimum permissible values this does not mean that grinding balls quality does not comply with DSTU 8538:2015<\/a>, because the upper limit of the norm is not regulated.<\/p>\n","protected":false},"excerpt":{"rendered":"
