Drawing Revision
Confirm dimensions by measuring the sample or using the customer drawing. Cross-check the drawing revision against the model on the equipment nameplate.
Materials and Processes
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
High-Manganese Steel Mn18Cr2
Solution-treated and water-quenched high-manganese steel; surface work hardening depends on impact and contact loading. Verify initial hardness against the material standard and drawing.
High-Manganese Steel Mn13Cr2
Standard manganese steel, a cost-effective option for crushing medium-hard materials
Metso XT710
Metso proprietary manganese alloy designed to balance wear resistance and toughness
Metso MX composite wear material
A manganese steel matrix with wear-resistant inserts. Metso states that its MX for cones products can achieve up to 2 times the wear life of standard manganese liners under suitable conditions. This is not a service-life guarantee for parts supplied through this website.
High-manganese steel Mn22Cr2
Candidate high-manganese steel; select for actual impact, abrasion and drawing requirements. Manganese content alone does not determine service life.
Wear and Replacement Criteria
Common wear patterns and maintenance guidance are outlined below. Determine replacement intervals from operating conditions, processed material and equipment performance data.
Common Wear Patterns
- The parallel chamber zone typically wears fastest; the liner profile gradually flattens and the product becomes coarser
- Material compression causes surface fatigue spalling and fish-scale wear patches
- Wear at the liner and adjustment ring mating surfaces increases installation clearance
- Wear of trapezoidal rack teeth, where fitted, reduces locking force
Replacement Criteria
Determine replacement timing from the model-specific maintenance manual and actual worn profile. Stop and inspect if CSS adjustment cannot correct abnormal product size or if through-cracks appear. Plan mantle and concave replacement together according to the chamber profile and wear condition.
Materials and Processes
Materials, heat treatment, composite construction and inspection requirements depend on the specific drawing, operating conditions and technical review.
Material Grade / Substrate
High-manganese steels Mn18Cr2 and Mn13Cr2, Metso XT710 and other specified grades
Heat Treatment Condition
Solution heat treatment with water quenching. Final hardness and microstructure must meet the drawing and agreed technical specification.
Composite / Hardfacing Requirements
Metso MX composite liners use a manganese steel matrix with wear-resistant inserts rather than hardfacing. Replace the complete liner; localized repair is not applicable.
Dimensions and Inspection
Verify critical dimensions against the drawing for the OEM part number, including fits, sealing surfaces and oil groove locations. Select nondestructive testing methods for the material, part geometry and technical agreement; MT applies only to suitably magnetizable ferromagnetic materials. Check copper alloy bushing hardness and uniformity as specified in the drawing.
Parts with the same name may not be interchangeable because of differences in machine model, drawing revision, mounting interface or material specification. Use the complete model, serial number, drawing number and drawing before manufacture.
