Hot Dip Aluminized Steel, also known as Hot dip Aluminium-Silicon (AS) steel or Alusi steel, is a type of coated steel that has been coated on both sides with aluminum-silicon alloy during a hot-dipped process.

AS (90%AL-10%SI) coating is a commonly used hot forming steel coating, mainly composed of metal compounds such as aluminum and aluminum-silicon, which can prevent the surface oxidation and decarburization of the steel sheet or coil. With its excellent corrosion resistance, high-temperature resistance, moist heat resistance, high heat reflectivity, and alkali resistance, Hot Dip Aluminized Steel is widely used in the manufacture of automotive reinforcements, as well as small appliances such as cookers, ovens, grills, and wall-hanging stoves.

Product Description

Features of Hot Dip Aluminized Steel

 

1

Hear resistance: With the AS coating, the heat resistance and high-temperature oxidation resistance are improved, making it suitable for applications in a corrosive atmosphere subject to high temperatures.

2

High heat reflectivity: Aluminized steel has a high level of heat reflectivity. The steel can still show a heat reflectivity of over 80% at a temperature below 400 °C, making it an ideal coating for thermal insulation applications.

3

Cost reduction: Overall operating costs can be reduced when aluminized steel is used as a replacement for more expensive materials.
