Materials and Processes
Review the following upper cheek plate material and process information when assessing specifications and alternatives.
XT710 manganese steel
Verify cheek plate material against the specific part drawing and material certificate. The XT710 designation alone does not establish composition, hardness or interchangeability with jaw plates.
Mn13Cr2 / Mn18Cr2
Mn13Cr2 and Mn18Cr2 are candidate chromium-bearing manganese steel grades. Confirm composition, heat treatment and suitability against the drawing, material standard and actual loading.
Installation
Cheek plates are bolted to the frame sidewalls; some models use a recessed mounting arrangement.
Wear and Replacement Criteria
Use the following upper cheek plate wear patterns and replacement considerations during maintenance.
Main wear zones
Material flow zones along the middle and upper chamber sidewalls, and around bolt holes. Upper cheek plate wear is generally lighter than lower cheek plate wear.
Replacement Criteria
Assess remaining thickness against the model-specific maintenance limits. Stop and inspect if there is wear-through, cracking or loosening caused by bolt-hole wear.
Recommended Actions
Measure thickness and check bolt tightness regularly. Schedule upper and lower cheek plate replacement according to actual wear and model-specific maintenance requirements.
Information Needed for an Inquiry
