Advantages of wear plates
1. Good impact resistance
The wear-resistant composite steel plate is made of low-carbon
steel or low-alloy, stainless steel and other tough materials as
the base material. The metal material not only has good wear
resistance, but also can withstand impact and wear such as falling
from a height during the transportation process.
2. Good heat resistance
The alloy wear-resistant layer is made of vanadium, molybdenum and
other alloy materials in the production process, so it can be used
and worn at a high temperature of ≤800 °C. Compared with ordinary
carbon steel substrates, it can only be used below 380°C, and
low-alloy heat-resistant steel sheets work below 540°C. This shows
how high the heat resistance coefficient of the wear plate is.
3. Good corrosion resistance
The wear-resistant plate contains a large amount of metallic
chromium, so it has good anti-rust and anti-corrosion properties.
It is especially suitable for the use of coal drop drums and
funnels. Not only solid and firm, but also to prevent coal
sticking.
