Test method for compressive resistance and wear resistance of wear-resistant steel plate
Wear-resistant steel is a special steel with excellent wear resistance. In the industrial field, wear-resistant steel is widely used in the manufacture of wear-resistant parts, such as excavator teeth, crusher tooth plates, etc. Understanding the compressive and wear-resistant properties of wear-resistant steels is a key factor in evaluating their applicability and reliability. The following will introduce several commonly used test methods to evaluate the compression and wear resistance of wear-resistant steel.

Compression test method: Compressive strength is an indicator of the ability of wear-resistant steel to resist external pressure and deformation. A common test method is the compression test. Install the sample on the machine, then apply a pressure perpendicular to the axis of the sample, and observe the deformation of the sample. By measuring the relationship between load and deformation, the compressive strength of wear-resistant steel can be calculated.

Abrasion resistance test method: Wear resistance is one of the most important characteristics of wear-resistant steel, which refers to the durability of wear-resistant steel under friction and wear conditions. One of the commonly used abrasion resistance testing methods is the cup and plate test. In this test, a certain quality of wear-resistant material (generally a material with poor wear performance, such as diamond) is used as an abrasive, and the wear of wear-resistant steel is observed by applying a load on the surface of the sample and performing reciprocating rotation. According to the wear degree of the sample, the wear resistance of the wear-resistant steel can be determined.

In addition, there are some other test methods that can be used to evaluate the wear resistance of wear-resistant steel, such as ball-on-disk test, roller test, etc. These test methods can quantify the wear resistance of materials under specific conditions, and provide an important reference for the reasonable selection and application of wear-resistant steel.
To sum up, the test methods of compressive resistance and wear resistance of wear-resistant steel are the key steps to evaluate its performance. By understanding the compressive and wear-resistant properties of wear-resistant steels, we can select wear-resistant materials for specific applications and improve the service life and efficiency of equipment.
