Jaw plate is the main wear part of jaw crusher, it has two types: swing and fixed types. Based on different demands, the material can be Mn13, Mn18, Mn13Cr2, Mn18Cr2, etc.
Jaw crusher, used as the primary crushing step, is widely used in mining, metallurgy, construction meterial, highway, railway, water conservancy and chemical industries for crushing various materials with compression strength less than 350MPa.
Trusted by customers in 30+ countries. Standard lead time 15-30 days.
High manganese steel Mn13, Mn13Cr2, Mn18Cr2 and Mn22Cr2, plus high chrome iron (Cr26) for fine crushing. We select the material based on your abrasive and impact conditions - send your working conditions for a recommendation.
Aftermarket parts fit Metso (HP, GP, C, NP series), Sandvik (CH, CS, H, S series), Symons 2FT-7FT, Terex Pegson, Kleemann, McCloskey, Shanbao, SBM, Telsmith, Minyu, Hazemag and more. Any model can be custom made by drawing or sample.
Yes. Send a drawing (PDF, DWG or CAD) or a used sample. We measure, draft and confirm all dimensions with you before production. OEM part numbers are welcome for reference.
Standard lead time is 15-30 days and samples ship in 7-15 days. MOQ is flexible - trial orders from 1 piece are accepted.
ISO 9001 certified factory (Kaixin Certification, CNAS-accredited; certificate valid through June 2028). Every shipment includes a Material Test Report (MTR) with chemical composition and mechanical properties.

| Material | Initial Hardness | Best For |
|---|---|---|
| Mn13 (ASTM A128) | HB 200-230 | General crushing with medium impact |
| Mn13Cr2 | HB 210-240 | Standard jaw plates and cone liners |
| Mn18Cr2 | HB 220-250 | High-impact, abrasive feed |
| Mn22Cr2 | HB 230-260 | Severe impact, hard and large rock |
| High Chrome Cr26 | HRC 58-62 | Blow bars, fine crushing of abrasive material |
* High manganese steel work-hardens under impact to 500+ HB at the wearing surface, giving long life in hard-rock crushing.
