On the web page to see more information on the plating aluminum plate, I do not know what is the difference between aluminized and aluminum plating performance?
Microstructure characteristics of hot dipped aluminized steelHot dip aluminizing steel to achieve the combination of atoms between iron and aluminum by metal bond, close together, as was shown under the microscope, from the outside to the inside with two aluminum film, three aluminum oxide layer, the alloy layer sequentially formed coating. If the coating of carbon steel, the banded structure and base metal contact.Coating thickness: if carbon steel, then the aluminum layer is 0.04-0.07mm alloy layer, the average 0.05mm. However, the thickness of each layer depends on the type of steel, the amount of carbon, and the temperature and time of the dipping. If the parent material is alloy steel, coating and the differences (omitted).
Brief introduction of hot dip aluminizing of steelHot dip aluminizing of steel is a new type of coating process for forming alloy aluminum layer on the surface of steel when molten steel products are inserted into molten aluminum liquid at a certain temperature.Hot dipped aluminized steel has high strength of steel matrix and corrosion resistance, wear resistance and high temperature resistance of aluminum layer. Its corrosion resistance is 5-10 times that of galvanized steel; it is resistant to sulfide and heat corrosion. Its performance is better than 18-8 stainless steel. Therefore, it can bring obvious economic benefits to users.
Hot dip aluminizing applicationsAluminized steel is widely used. The type I aluminized steel plate, originally developed, is mainly used in automobile exhaust pipes and silencers. Type II is used mainly for roofing and side walls of buildings, as well as for chemical containers. The aluminized steel wire produced by the new process is expected to be used as the core of the transmission line instead of the galvanized steel wire. Aluminized steel pipe has been widely used in power plants, boilers, water wall tubes, steam pipes, heat exchangers and so on. Aluminized steel structure has been widely used in power transmission tower, told highway guardrail and so on.
