Aluminized Steel Sheet

Aluminized steel is a type of steel that improves its corrosion and heat resistance through a thermal diffusion process. The process involves immersing the steel components in molten aluminum bath, which is simple and suitable for continuous operation. However, due to the high melting point of aluminum at 660°C, the steel pieces to be aluminized require pretreatment and activation, as well as prevention of oxidation. Steel plates, strips, and wires can all undergo surface aluminization, with the thickness of the aluminized layer reaching up to 0.05mm. The heat resistance of general aluminized steel can reach 700°C, and it also has excellent heat-reflective properties, reflecting about 75% of radiant heat. Aluminized steel can be used in muffle furnaces, local heating devices, heating stoves, and more.
