I believe many customers know that when purchasing crusher wear-resistant parts, you can ask suppliers to provide material inspection reports. The material inspection reports provided by different suppliers are slightly different. Even the inspection reports of the same manufacturer may have some differences in different orders. Today we will briefly describe the meaning of each chemical element in the material inspection report.
Here is a sample suit for Nordberg HP300 feed plate, PN: 1055981158, material Mn13Cr2. (This material also used for crusher mantle and crusher concave, China jaw plate, cheek plate jaw crusher, etc.)
As the name suggests, Mn13Cr2 means that the high manganese steel content is 13% and the high chromium content is 2%. Therefore, as long as the content values are within the range, there is no problem.
The advantages of high manganese steel are wear resistance and good toughness, but high chromium steel has better wear resistance and is more expensive. The disadvantage of high chromium steel is that it is very brittle and the product is easy to break during use, so the more chromium steel, the better. The life of Cr is 2-2.5 times that of Mn.
P and S stand for phosphorus and sulfur respectively. They are impurities, so the lower their content, the better.
In addition to the above materials, we often encounter Mo. Its function is to increase the fineness of tissue particles and increase toughness, but the price is very high.
Titanium carbide, also known as cemented carbide, is expensive, but its lifespan is 1.5-1.8 times that of Mn.
