What is the performance index of Q235B steel plate?

Q235B steel plate is a new type of modern composite wear-resistant steel plate material, which has been widely used in developed countries since 1960s. With the development of science and technology and the demand of market economy in China, the special properties and practical economic value of hardfacing composite steel plate have been gradually recognized and used by some large-scale industrial and mining enterprises with advanced consciousness, and have created considerable economic benefits for enterprises.

1. Extraordinary wear resistance ratio:
The wear test shows that the wear resistance of chromium carbide Q235B steel plate is 10-30 times higher than that of ordinary steel plate, 5 times higher than that of cast stainless steel and high manganese steel, and 1 times higher than that of as cast high chromium iron, which is roughly equal to that of ceramic magnetism HRC≤63.

2. High impact resistance ratio:
Because the base metal is Q235A soft steel base plate, the surface is made of chromium carbide multi-element hardfacing composite super hard material. It fully embodies the dual advantages of the composite material, which has both extraordinary wear resistance and impact toughness. This is inferior to as cast wear-resistant material. (the traditional casting has poor impact resistance and is brittle and easy to fracture)

3. Convenient processing performance ratio:
The repairman can cut and shape the wear-resistant steel plate according to the size of the site (plasma cutting). It is very convenient to weld the wear-resistant steel plate on the surface of the wear-resistant parts (carbon steel surface). It can also be processed into countersinks and connected to the components with bolts. It can also be bent inward to form plate components such as wear-resistant pipes, dust removal elbows, and various special-shaped Tianyuan places. (the wear-resistant plate of casting can not be assembled by welding, and it is difficult for cast steel to cast large area wear-resistant plate. In addition, the traditional casting is very heavy, because the reinforcement is designed to prevent deformation.)

4. High performance and low cost ratio:
Although the cost of Q235B steel plate is increased, the price is 3-5 times higher than that of ordinary steel plate and 25% cheaper than that of high chromium stainless steel casting. However, considering the service life of the parts, reducing the maintenance cost, downtime and other losses of all human and financial resources, due to the rational use of materials, its performance brings multiple gains to the production.
