Aftermarket Crusher Wear Parts: Jaw Plates, Cone Liners, Blow Bars
Aftermarket wear parts for jaw, cone, impact, hammer and roll crushers, cast in our own foundry in high-manganese steel (Mn13 / Mn18Cr2 / Mn22Cr2Mo), chromium-molybdenum alloy steel and high-chromium white cast iron. Parts fit Sandvik C series, Metso/Nordberg HP and GP series, Terex and other common machines, and PE/PEX jaw crushers. Anything not in the pattern library is cast from your drawing — part of our custom metal casting program.
Crusher Wear Part Families
Each crusher type has its own wear mechanism and material route. The table below maps the castings we supply by machine type.
| Crusher type | Castings | Material route |
|---|---|---|
| Jaw crushers | Fixed and swing jaw plates, cheek plates, toggle plates | High-Mn for hard rock; Cr-Mo where impact is moderate. Jaw crusher parts |
| Cone crushers | Mantles, concaves, bowl liners | Mn18Cr2 / Mn22Cr2Mo by cavity position. Cone crusher parts |
| Impact crushers | Blow bars, impact plates | High-chromium white iron; ceramic-composite for abrasive duty. Impact crusher parts |
| Hammer crushers | Ring hammers, liners | Forged-equivalent cast grades; power-plant ring hammers available |
| Roll crushers | Roll shells, wear plates | Cr-Mo alloy steel |
Material Grades Across Crusher Types
| Grade | As-cast hardness | In service | Best for |
|---|---|---|---|
| Mn13 (Hadfield) | HB 170–230 | Work-hardens to HB 450+ | High-impact cavities |
| Mn18Cr2 / Mn22Cr2Mo | HB 180–260 | HB 450–550 | Strong-impact, hard rock |
| Cr-Mo alloy steel | High initial hardness | Stable | Moderate impact |
| High-chromium white iron | HRC 58+ | Abrasion-dominant | Low-impact, high-abrasion |
High-manganese grades work-harden under impact — the surface hardens while the core keeps its toughness. For the full grade-by-grade selection logic, see our crusher liner selection guide: Mn13 vs Mn18Cr2 vs high-chromium.
Compatibility
Our pattern library covers the common Metso/Nordberg HP and GP, Sandvik C, Terex and PE/PEX ranges. Send the machine model or the worn part, and the casting is matched to it. Custom parts from drawings are routine practice.
Manufacturing and Quality Control
Induction-furnace melting with controlled Mn/C ratio for manganese steel; water-toughening retains the austenitic structure that enables work-hardening. Every heat is checked by spectrometric analysis; finished parts pass hardness gradient and dimensional inspection. ISO 9001 quality system throughout; material and test reports supplied on request.
