Jaw plates are commonly made from manganese steel, an alloy that boasts high wear resistance and toughness. Manganese steel typically contains between 11% to 14% manganese, which contributes to its unique and advantageous properties. The addition of manganese enhances the alloy's hardenability, allowing it to become exceptionally hard when subjected to heavy impacts. This characteristic makes manganese steel an ideal choice for high-stress applications, such as crushing abrasive materials in mining.

One of the most critical components of a jaw crusher is the jaw plates. These are the surfaces that come into direct contact with the material being crushed. They typically come in two varieties the fixed jaw plate and the movable jaw plate. The fixed jaw plate is stationary and mounted on the frame, while the movable jaw plate moves back and forth, creating a crushing motion. The wear and tear of jaw plates are significant since they constantly encounter abrasive materials. Hence, they are often manufactured from high-grade manganese steel to enhance their durability.
