Best Jaw Crusher Wear Parts Manufacturer In China
INTRODUCTION
High manganese steel jaw plates are the most essential wear parts of jaw crushers. Manufactured using Mn13Cr2 and Mn18Cr2 alloy steel, our jaw plates offer superior impact resistance, excellent work-hardening ability, and exceptional durability in the toughest crushing environments. Designed for both primary and secondary crushing, these jaw crusher plates guarantee stable performance and extended wear life, significantly reducing maintenance downtime and operational costs.
Our Mn13Cr2 and Mn18Cr2 high manganese jaw plates are fully compatible with a wide range of crusher brands such as Metso, Sandvik, Terex, Kleemann, Trio, Shanbao, PE Series, C Series, and more.
Product Overview
High manganese jaw plates perform the crucial function of crushing rocks, ores, limestone, granite, basalt, river stone, and various hard materials inside a jaw crusher. The material Mn13Cr2 and Mn18Cr2 is specifically designed to withstand strong impact loads and repeated crushing forces. Each jaw plate will work-harden during operation, ensuring the surface becomes harder and more wear-resistant over time.
Our jaw plates are produced through a strict foundry process, advanced heat treatment, and precise machining to ensure optimal performance.
Key Features of Our High Manganese Jaw Plates

Prevents cracking or breakage under severe crushing conditions.Excellent Chemical Composition
Strict alloy control ensures consistent mechanical properties.Precision Machining and Perfect Fit
Ensures smooth installation and minimal downtime.Optimized Tooth Profiles
Suitable for different crushing stages: coarse, medium, and fine crushing.OEM & Customized Design Available
Profiles, hardness, alloy content, and thickness can be customized.
Material Grades: Mn13Cr2 and Mn18Cr2 Explained
1. Mn13Cr2 Jaw Plates
Mn13Cr2 is a standard high manganese steel grade featuring moderate hardness, high toughness, and excellent impact resistance. It is suitable for:
Soft to medium-hard rock materials
Primary crushing applications
Low-abrasion crushing environments
Situations requiring high toughness
Advantages of Mn13Cr2 jaw plates:
Excellent work-hardening performance
High toughness for impact-rich environments
Suitable for general quarry and mining usage
2. Mn18Cr2 Jaw Plates
Mn18Cr2 manganese steel is a premium wear-resistant grade with improved hardness, higher manganese content, and better abrasion resistance. It is widely used in:
Medium to hard materials
High-impact crushing conditions
High-output crushing lines
Larger jaw crushers
Advantages of Mn18Cr2 jaw plates:
Longer service life compared to Mn13Cr2
Excellent resistance to wear and abrasion
Ideal for hard materials such as granite, basalt, and iron ore
