Difference between surface oxidation galvanizing and stainless steel in Dalian

Hot dip galvanizing: durable and anti-corrosion. The standard quality hot dip galvanizing antirust thickness makes it have good durability; The toughness of the coating is strong. The hot-dip galvanized zinc coating forms a unique smelting metal structure, which can withstand the mechanical damage during transportation and use.

The main factors affecting the layer thickness of hot-dip galvanizing production line are: the composition of base metal, the surface roughness of steel, the content and distribution of active elements silicon and phosphorus in steel, the internal stress of steel, the geometric size of workpiece and hot-dip galvanizing process. China's hot dip galvanizing standard is mainly divided into several parts according to the thickness of steel. The average thickness and local thickness of the zinc coating shall reach the corresponding thickness to determine the corrosion resistance of the zinc coating. For workpieces with different steel thickness, the time required to achieve heat balance and zinc iron exchange balance is different, and the thickness of coating is also different.

Difference between surface oxidation galvanizing and stainless steel in Dalian

1. Different concepts: galvanizing refers to coating a layer of metal zinc on the surface of the steel plate in order to prevent the surface of the steel plate from corrosion and prolong its service life. This kind of galvanized steel sheet is called galvanized sheet. Corrosion resistant medium of stainless steel, such as acid and alkali resistant medium, is also called corrosion resistant medium of stainless steel.

2. Different processing technology: galvanizing is mainly to coat a layer of dense zinc on the surface of steel. Stainless steel is the addition of other metal elements inside the steel, which makes the product rustless due to internal structural changes.

3. Different application fields: galvanized sheet and strip steel products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery, commerce and other industries. For example, it is used for building roof panels, roof grilles, etc; Kitchen utensils, etc; Storage and transportation of materials, packaging tools, etc. Stainless steel is mainly used in the construction field. It is one of the high-strength metal materials for construction. It is also used in food processing, catering, brewing, chemical industry and other fields with high sanitary conditions.

In fact, the production process of hot-dip galvanizing production line focuses on basically completing the upgrading and adjustment, bringing better redo and upgrading in the processing technology, and also completing better improvement, which has better effect in modern processing solutions. According to the processing solution, the service life of stainless steel plate components can be better improved, and the stability coefficient can be ensured.

The overall appearance of hot-dip galvanizing is slightly rough, which will produce process water marks, dropping tumors and other manifestations, especially one end of the workpiece is obvious, and the whole is silvery white. The surface layer of electro galvanizing is relatively smooth, mainly yellow and green. Of course, there are colorful, cyan and white, green light and so on. The whole workpiece basically will not have zinc tumors, lumps and other phenomena.
