Based on different working conditions, Qiming Machinery supplies different materials to suit. There are 4 kinds of materials for jaw plates.
Manganese steel is made by alloying steel, containing 0.8 to 1.25% carbon, with 11 to 15% manganese. Mangalloy is unique non-magnetic steel with extreme anti-wear properties. The material is very resistant to abrasion and will achieve up to three times its surface hardness during conditions of impact, without any increase in brittleness which is usually associated with hardness. This allows manganese steel to retain its toughness.
There are some grades for manganese steel jaw plates:
- Mn14Cr2 Jaw Plates. Mn14cr2 jaw plates are used in crushing soft stone. For example, it has a good life when crushing the easy and non-abrasive blasted rock, non-abrasive gravel, and non-abrasive round rock.
- Mn18Cr2 Jaw Plates. Mn18Cr2 is the most popular material for casting jaw crusher jaw plates. This Mn18Cr2 jaw plates widely in crushing difficult and non-abrasive blasted rock, medium and non-abrasive,non-abrasive gravel, and non-abrasive round rock.
- Mn22Cr2 Jaw Plates. Mn22Cr2 jaw plates are widely used in crushing hard and abrasive stones. Under our technology, its span life much better than normal.

This material is developed by Qiming Machinery, it has improved our customer jaw plate by TIC(titanium carbide) insert. Compare with normal manganese jaw crusher liners, TIC insert wear parts span life can be 2-3 times. Based on our customer feedback, the more hard material to crush, the long the span life.

Alloy Steel Jaw Plates
This material is developed by Qiming Machinery. We use alloy steel to cast small jaw crusher jaw plates. Normally, the weight of alloy steel jaw plates less than 2 tons. After the jaw plate is energized, it can achieve the function of magnetic separation of raw materials.

Microalloy Steel Jaw Plates
This material is also developed by Qiming Machinery. By adding some rare elements into manganese steel, the manganese steel jaw plate gets more good wearable and hardness. This kind of material is widely used in crush copper mine.
