What are the characteristics of weathering steel?

With the continuous improvement of my country's comprehensive national strength, the weathering steel industry is also constantly developing, and weathering steel also has many functions. For example, it can be used in railway vehicles, oil derricks, containers, and platforms for oil extraction. Because of its good corrosion resistance.

Weathering steel is actually a steel resistant to atmospheric corrosion. It is a low-alloy steel series between ordinary steel and stainless steel. Weathering steel is made of plain carbon steel and added a small amount of corrosion-resistant elements such as copper and nickel. It has the strength of high-quality steel. Toughness, ductility, forming, welding, abrasion, high temperature, and fatigue resistance. The weather resistance of this steel is several times higher than that of other steels.

At the same time, it has the characteristics of rust resistance, corrosion resistance and longevity of components, thinning and consumption reduction, and labor and energy saving. This kind of just has its outstanding visual expressive power, this is because the steel will change over time, and its color vividness and saturation are higher than ordinary building materials, so it will be easier to highlight It also has a strong ability to shape the shape, which can be easily molded into a rich variety of shapes, and can ensure a good integrity. These characteristics are difficult to achieve for wood and stone, and they are rusting. In the process.

Rust spots will begin to grow in the first stage;
In the second stage, the rust spots will be thicker and denser, the rust water of ordinary steel plates will be more, and the bottom of the workpiece will be black.
In the third stage, the authentic weathering steel will have a clear and dense rust layer, which is adhered to form a protective layer, and it will hardly fall off when rubbed by hand.
