Wear resistant plate refers to multilayer wear-resistant steel plate plated with high chromium alloy on ordinary steel plate, which is a plate product used under equipment wear. It is a wear-resistant layer with high hardness and excellent wear resistance on the surface of low carbon steel or low alloy steel with good toughness and plasticity
Surface inconsistency: only pickling and passivating the weld will cause uneven surface of Hardox400 wear-resistant plate and affect the appearance.
Uneven polishing and passivation: after manual polishing and pickling passivation, it is difficult to achieve uniform treatment effect on a large area of plate, and the ideal uniform surface cannot be obtained. And the cost of working hours and auxiliary materials is also relatively high.
3. Weld defects: serious weld defects are compensated by manual and mechanical grinding, resulting in uneven surface and affecting appearance.
4. Scratch is difficult to remove: after pickling and passivation, all kinds of scratches produced in the processing process can not be removed, and impurities such as carbon steel and spatter adhered on the surface of Hardox400 wear-resistant plate due to scratch and welding spatter can not be removed. In the presence of corrosive medium, chemical corrosion or electrochemical corrosion rust is caused.
5. The scratch caused by human factors is more serious: in the process of hoisting, transportation and structural processing, the scratch caused by collision, dragging, hammering and other factors is more serious, which makes the surface treatment more difficult, and is also the main reason for the corrosion after treatment.
Pickling capacity is limited: pickling passivation paste is not omnipotent, the black scale produced by plasma cutting and flame cutting is difficult to remove.
7. Equipment factors: the scratches and creases of profiles and plates during rolling and bending are also the main causes of corrosion after treatment.
8. Other factors: in the process of purchasing and storing Hardox400 wear-resistant plate raw materials, the collision and abrasion caused by hoisting and transportation are also very serious, which is one of the reasons for corrosion.
