High-hardness wear-resistant steel plate is a medium-carbon, high-hardness wear-resistant plate; high-hardness steel plate can be processed and manufactured according to the traditional cutting method under appropriate preheating conditions, according to the recommended preheating temperature and cutting speed.
Precautions for cutting high hardness steel plate:
1. Slow cooling of the stack of cut pieces can reduce the risk of cracks after cutting.
2. Heating after cutting can effectively prevent delayed cracks, and the heating temperature is consistent with the preheating temperature.
3. The temperature of the workpiece will increase during the oxygen cutting process. The smaller the workpiece, the higher the temperature, which is more than 500. degree, the workpiece will soften to a certain extent.

Due to the extremely high hardness of high-hardness wear-resistant steel, cold working of the material is not recommended.
Welding, drilling and tapping of high-hardness wear-resistant steel plates are very difficult and require high equipment capabilities.
The ultra-high mechanical properties of high-hardness wear-resistant steel sheets are obtained by quenching and subsequent tempering under necessary conditions, and the ultra-high mechanical properties cannot be maintained at temperatures above 250 degrees Celsius.
High hardness wear resistant steel plates cannot be used for further heat treatment.
Safety instructions and suggestions for high hardness wear-resistant steel plates:
High-hardness wear-resistant steel plates are designed to be used in wear-resistant components, not structural components.
In order to avoid damage caused by unsafe and inappropriate use of high-hardness steel plates.
The purchaser or user must take appropriate and necessary security measures under the responsibility to avoid injury or damage to people or equipment during the use and processing of high-hardness wear-resistant steel.
