Extended data:

Formation of weathering steel;

After adding trace elements such as phosphorus, copper, chromium and nickel. When it enters the steel, a dense and highly adherent protective film is formed on the surface of the steel, which prevents the corrosion from spreading and developing to the inside, protects the matrix under the rust layer and slows down its corrosion rate.

The amorphous spinel oxide layer formed between the rust layer and the matrix has a thickness of about 50μ m ~100μ m, which is compact and well combined with the matrix metal. Because of the existence of this dense oxide film, oxygen and water in the atmosphere are prevented from infiltrating into the steel matrix, the corrosion development of steel materials is slowed down, and the atmospheric corrosion resistance of steel materials is greatly improved.

Weathering steel is a kind of steel system that can be used thinly, exposed or simplified, which can make products corrosion-resistant, prolong life, save labor and reduce consumption, and upgrade. It is also a steel system that can be integrated into modern metallurgical new mechanism, new technology and new technology to make it develop and innovate continuously.
