Aluminized steel is steel that has been hot-dip coated both sides with aluminum-silicon alloy. This process assures a tight metallurgical bond between the steel sheet and its aluminum coating, producing a material with a unique combination of properties possessed neither by steel nor by aluminum alone. Aluminized steel shows a better behavior against corrosion and keeps the properties of the base material steel for temperature lower than 800 °C(1,472 F). For example, it is commonly used for heat exchangers in residential furnaces, mufflers, ovens, ranges, water heaters, fireplaces, bar-b-que burners, and baking pans.
Characteristics are defined by the exact metals used, as well as the process used.
The basic structure of aluminized steel is a thin aluminum oxide layer outside, then an intermetallic layer that is a mix of aluminum, silicon, and steel, and finally a steel core. Aluminized Steel is highly resistant to corrosion and shows high levels of heat reflectivity.
These Air Cooled Type Heat Exchangers are used in oil, gas, petrochemical, refinery, and power and condensation plants. All type of fluids in process industries are cooled in Air Fin Coolers with the use of atmospheric air, as the cooling media which resulting in economy in running costs.
Our Air cooled Heat Exchangers are used for high pressure, high temperature applications in process industries with metallurgy suitable for highly corrosive fluid medias.
