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.

1. High abrasion resistance and impact resistance

Through scientific and reasonable alloying element formula, the alloy steel lining plate in the double medium quenching has good physical and chemical properties, hardness HRC45-55 above, impact toughness value 25J above, and service life is more than 2 times that of high manganese steel.Able to withstand tremendous impact force.It can keep the surface shape of the lining board for a long time in order to ensure that the mill can increase the output by more than 5% stably.

⒉ High strength and high toughness

In the process of lining plate quenching, the special double medium quenching agent with good thermal stability is used as the medium, so that the product can achieve the match of high strength, high hardness and high toughness, so as to meet the technical requirements of wear resistance

3. High cost performance and good adaptability

After the advanced double medium quenching process, it has the characteristics of high quenching hardness and high toughness value, so that the lining plate has good wear resistance. Compared with the lining plate of high manganese steel, the lining plate of alloy steel ball mill in the middle alloy double medium quenching shows excellent cost performance.Suitable for mine wet mill, dry mill, mixed mill, etc.

The main material in the hammer of high manganese steel is high manganese steel (Mn13,Mn13Cr2 and Mn18Cr2). With the continuous development of wear-resistant materials, the high toughness of high manganese steel is incomparable to other wear-resistant materials.
