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.
