What are the main characteristics of Q235B steel plate?

1. Excellent wear resistance, continuous use for more than 10 years
The wear resistance of the inner wall wear-resistant layer of Q235B steel plate is 25 times that of manganese steel and 12 times that of cast iron of Q235B steel plate, which has been proved to be excellent. Q235B steel plate greatly reduces the wear of equipment in the application of pulverizing system.

2. Q235B steel plate has high strength, high hardness and light weight
The hardness of the inner wear-resistant layer of centrifugal cast Q235B steel plate is as high as hv1200-1500, which is equivalent to tungsten cobalt carbide. Its weight is only 1 / 4 of the ordinary Q235B steel plate, which is easy to install and replace. The Rockwell hardness of the wear-resistant layer is hra82-90, which is much higher than that of wear-resistant steel and stainless steel.

3. It is installed firmly, with good heat resistance and corrosion resistance
The melting point of wear-resistant layer of Q235B steel plate is 1860 ℃. The structure of wear-resistant layer and steel layer is special due to process reasons, and the stress field is also special. When the temperature rises to 950 ℃, Q235B steel plate is put into cold water for many times, and its wear-resistant layer does not crack or crack, showing the incomparable thermal shock resistance of ordinary Q235B steel plate. The inner layer of Q235B steel plate is dense α - Al2O3 with acid resistance of 90-98%.

4. The inner wall of Q235B steel plate is smooth without powder plugging
Q235B steel plate has no gap, its surface is bright and clean, and there is no high and low expression of wear-resistant layer inside. The wear-resistant layer is sintered at high temperature, with compact structure and smooth surface after grinding and deburring treatment.
