What is the difference between cladding wear plate and ordinary steel plate
Surfacing wear-resistant plate is mainly divided into alloy wear-resistant steel plate and composite wear-resistant steel plate. Alloy wear-resistant steel plates are nm400, JFE-EH400, DILLIDUR 400 and so on. Composite wear-resistant steel plate is also known as bimetallic wear-resistant steel plate by making wear-resistant alloy layer by welding on ordinary steel plate.
Surfacing wear plates are mainly divided into alloy wear plates and stacked wear plates. Alloy wear plates include nm400, JFE-EH400, DILLIDUR 400, etc. Stacked wear plates are made with a wear-resistant alloy surface welded to a general plate, also known as bimetallic wear plates.
Regardless of the type of wear-resistant plate, the surface may not differ much from the general plate, but the function and composition, etc. are far apart. So what is the difference between wear-resistant plate and general plate?
1. Composition is not the same
All plates are injected with steel, cooled and extruded plates, according to the thickness can be divided into thin plates, medium plates, thick plates and so on. According to the utility and composition, it can be divided into general plate, alloy plate, wear-resistant plate, stainless steel and so on.
Among them, the wear-resistant plate belongs to the plate, with good wear resistance, impact resistance and toughness properties, including bimetallic wear-resistant plate is more special, belongs to the reprocessing plate.
2. Different uses
Wear-resistant plate wear resistance is good, can be used in high wear conditions, the service life can not be compared with the general plate, with impact resistance and high toughness security. Therefore, wear-resistant plate can often be seen in mines, machinery, coal mines, wharves, cement and other places, can greatly improve production efficiency and reduce costs.
3. Rust is not the same
It is difficult to distinguish between wear-resistant plate and general plate without rust, so when you buy, you need to check the quality assurance certificate and other certificates provided by the factory, or take the sample to a third-party organization for inspection.
After the plate is rusted, it can be judged according to the traces of rust. General plate rust more, rust, rust, wear-resistant plate melting point is smaller and denser.
4. Price is not the same
Surfacing wear-resistant plate belongs to the special steel, production process and technical requirements than the general plate is much higher, so the cost is certainly not the same. Buy wear-resistant plate need to choose professional enterprises. Uncounted businessmen can't pretend to be general plate and lose a lot of money.
The structural characteristics of the surfacing wear plate: the wear plate consists of two parts: the low carbon plate and the alloy wear-resistant surface, and the alloy wear-resistant surface is generally 1/3~1/2 of the total thickness. when working, the body has the comprehensive performance of strength, toughness, plasticity, etc., which can resist the external force, and the alloy wear-resistant surface has the wear-resistant property to meet the requirements of the specified working conditions.
There is metallurgical bonding between the alloy wear surface and the base body of the surfaced wear plate. Through special equipment using automatic welding process, high hardness self-protecting alloy wire uniformly welded to the substrate, the number of superimposed surfaces for 1 ~ 2 surfaces ~ 2 surfaces, superimposed in the process of alloy shrinkage is not the same, so the emergence of uniform transverse cracks is a prominent feature of wear-resistant plate.
