China's current general wear resistant material series of high manganese steel series: such as high manganese steel (ZGMN13),
High manganese alloy (Zgmn13Cr2MoR), ultra-high manganese alloy (Zgmn18Cr2MoR), etc.
High manganese steel (such as ZGMN13) under severe impact or contact stress, its surface will rapidly harden, while the core still maintains a strong toughness, hard outside and tough inside both wear resistance and impact resistance.And the heavier the impact on the surface, the more full the surface hardening, the better the wear resistance.Because the hardness of high manganese steel itself is very low (HB170-230), the wear resistance is extremely limited before hardening. If the surface of high manganese steel is not enough to bear the impact force, the surface can not be fully hardened (after full hardening, the surface hardness can reach HB550 or below, otherwise), then the wear resistance will not play a role, and the wear resistance will not be shown.
Because Zgmn18Cr2 contains more manganese, the surface hardening can be more sufficient, so more wear-resistant.
Of course, ZGMN18Cr2 series (such as ZGMN18Cr2MORE) is also more expensive than ZGMN13 series.
The performance grade of ball mill bolts can be divided into 10 performance grades: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9, among which the strength bolts above 8.8 grade (including) are made of medium carbon steel and alloy steel after heat treatment, and these bolts are called high strength bolts, and the rest are generally called ordinary strength bolts.
