Wear-resistant steel plate is a modern new type of composite wear-resistant steel plate material. Since the 60s of the 20th century, it has been promoted and used in industrially developed countries. With the needs of China's scientific and technological progress and market economic development, the special performance and practical economic value of wear-resistant overlay composite steel plate have gradually been recognized and used by some managers with advanced consciousness in some large industrial and mining enterprises, creating considerable economic benefits for enterprises.

Wear-resistant steel plate is a modern new type of composite wear-resistant steel plate material. Since the 60s of the 20th century, it has been promoted and used in industrially developed countries.

The comprehensive properties of wear-resistant steel plates are as follows:
  
1. Extraordinary wear resistance ratio:
  
The wear test shows that the wear resistance of chromium carbide wear-resistant steel plate is 10-30 times higher than that of ordinary steel plate, 5 times higher than cast stainless steel and high manganese steel, 1 times higher than cast high chromium iron, and roughly equivalent to the wear resistance of ceramic magnets.
  
2. High impact ratio:
  
Since the base metal adopts Q235A low carbon steel matrix, the surface adopts chromium carbide multi-wear-resistant overlay welding composite superhard material. It fully reflects the dual advantages of composite materials, with extraordinary wear resistance and impact toughness. This is better than casting wear-resistant materials. (Traditional castings have poor impact resistance, are fragile and easy to break)
  
3. Convenient processing rate:
  
Maintenance personnel can cut and shape arbitrarily according to the size of the site (plasma cutting), and it is convenient to weld the wear-resistant steel plate to the surface of the wear part (carbon steel surface), or process it into a counterbore and bolt it to the part. It can also be formed by cold bending inward, such as wear-resistant pipes, dust elbows, various special-shaped rounds and other plate components. (The wear plates of castings cannot be assembled by welding, and it is difficult to cast large-area wear plates with cast steel.) In addition, conventional castings are bulky because stiffeners are designed to prevent deformation)
  
4. High performance and low cost ratio:
  
Although the cost of wear-resistant steel plate increases, its price is 3-5 times higher than ordinary steel plate and 25% cheaper than high-chromium stainless steel castings. However, considering the loss of manpower and financial resources such as the service life of machine parts, reduced maintenance costs, downtime and poor production, its performance brings a double gain to production due to the rational use of materials.
  
The stainless steel mesh contains molybdenum, which is resistant to corrosion and high temperature, so it is not difficult to infer that the high temperature resistance of 316 stainless steel mesh is superior. 316 steel mesh has a strong structure and high tensile strength and toughness.
  
The surface of the mesh is flat, and it will not deform even if it is exposed to high temperature for a long time, and the aging rate is very slow. There are many stencils that can be used at high temperatures, such as those used for insulating pipes. He uses 50 knives of stainless steel mesh, 60 knives of stainless steel mesh for food factories, and 100 knives of stainless steel mesh for power plants. It is very necessary to install stainless steel mesh filters. It rained in the middle of the night last night and it kept raining in the morning. Standing water in low-lying areas of the road should be below the knee. What is needed is rapid drainage to restore normal roads as soon as possible and facilitate pedestrian traffic. Auxiliary installation of stainless steel mesh in road sewers.
  
Rainwater can be drained as quickly as possible, and stainless steel can be used for many years. Steel mesh filter plate is a product produced from metal plate. Resistant to rainwater washout, resistant to rainwater acidity and alkalinity, longer service life.
