2. Provide customers with drawings based on their machine models, spare parts dimensions, etc.
3. After sales, we will continue to pay attention to the usage of the product and provide timely help.
If you need detailed technical information of the product or cannot find the product you need on the website, please email us（cnwearparts@lyzhili.com）, because we are a customized factory for crusher spare parts.
Our Jaw plates are cast from the highest grade of ferro Manganese, to provide the hardest composition for maximum wear resistance. We offer a wide variety of tooth profiles & surface shapes to best suit your crushing needs.
The jaw plate is a key wear-resistant spare part in the jaw crusher. A set of jaw plates consists of a movable jaw plate and a fixed jaw plate.
The materials of high manganese steel Jaw plates include Mn13Cr2, Mn18Cr2, Mn13 or Mn18 ｉｎｓｅｒｔ tungsten-molybdenum alloy bars and surface surfacing wear-resistant alloys.
Applicable working conditions: Suitable for cement plant, stone factories and other rocky places with poor conditions.
Zhili New materials jaw plates have the following features:
1.Designed for maximum operational flexibility;
2.Maximize uptime;
3.Reduce wear;
4.Optimize production;
5.Extend service life.

We use proper alloying and and related technological measures to make High chromium iron Jaw plates’surface hardness reaches more than 58HRC , during the process of wearing will maintain high hardness and high wear resistance.
Applicable working conditions: Suitable for making wearable spare parts with lower impact load and simpler shape.

1：There are no exact corresponing value between rockwell hardness(HRC) and brine hardness(HB),so ,this two kind of hardness value can be inspend used 。 | ||||||
Alloy steel jaw plate is a widely used at present. It has relatively high hardness and appropriate toughness which is enough to resist the fluid wear and repeated impact of the material, so it shows good wear resistance performance.
Applicable working conditions: Widely used in Cement, Quarry and Mining plants
