The jaw plates of the jaw crusher are made of high-quality manganese steel Mn13Cr2 and Mn18Cr2, which are renowned for their excellent impact resistance and work hardening properties. Under heavy crushing loads, their surface hardness can be increased from 200HB to over 500HB, significantly extending their service life. We offer fixed and movable jaw plates for most common models, including PE150x250, PEX150X750,PE250x400, PEX250X1000,PE 400x600, PE 400x900, PE 500x750, PE 600x900, PE 750x1060, PE 900x1060, PE 900x1200, PE 1000x1200, PE1200x1500, PE1500x1800, PEX150x750, PEX250x750, PEX250x1000, PEX250x1200, and PEX300x1300.
