High manganese steel fixed jaw plates and movable jaw plates are critical wear parts in crushers, designed for crushing hard materials like ores and rocks. Made from high manganese steel (typically 10-15% manganese), they leverage the material’s unique work-hardening property—surface hardness rises sharply under impact, while the core retains toughness.

The fixed jaw plate is stationary, forming one side of the crushing chamber, while the movable counterpart oscillates, squeezing materials between them. Their robust structure resists severe abrasion and repeated impacts, ensuring long service life. Ideal for heavy-duty crushing, these plates balance durability and performance, making them indispensable in mining and construction crushers.
