In addition to being used in landscape architecture design and decoration, weathering steel is also widely used in construction projects. Vehicles. Roads highway Bridges. Towers and other steel frames exposed in the air for a long time, as well as production and processing containers. Railway rolling stock. Oil door crane. Seaport construction engineering. Changqing Oilfield Company integrated service platform and other parts. The important reason why it is used as a road, highway, bridge and coastal area is that the air humidity in such areas is far higher than that in other areas, so the corrosion level needs to be much more serious. Relevant experts and professors have tested on the spot, even if the average corrosion depth of weathering steel in coastal areas is about 0.02mm/ year, its corrosion resistance is expected to greatly exceed the general carbon steel plate.

The gas corrosion resistance of weathering steel is 3 to 10 times that of general alloy tool steel, and the expected effect of painting is 2-8 times that of general carbon steel after its application period grows up to 40 years.
Weathering steel is also known as gas corrosion-resistant steel, which generally adopts the production process line of concentrate feeding into the furnace - feeding the soil wire in the concentrator - controlled rolling and controlled cooling. Add carbon to the production process. Copper. Phosphorus. Chromium. Sulfur. Nickel, calcium, manganese, molybdenum and other rare elements.
Aluminum alloy composition and net weight percentage moisture content in weathering steel: C: 0.12 ~ 0.21.Si: 0.2 ~ 2.0.Mn: 0.7 ~ 2.0.S≤0.036.P≤0.034.Cu: 0.10 ~ 0.40.Al<0.2,
The others are Fe and trace element sediment. Phosphorus is added to stainless steel plates. After copper, chromium, nickel and other trace elements, the surface of the stainless steel plate causes a high density and strong bonding force of the original film, prevent the corrosion from spreading and developing trend, maintain the basic maintenance of the rust layer to reduce its corrosion rate.
Compared with the general carbon steel plate, the steel plate is further improved. Molding. Welding and cutting. Cavitation erosion. High temperature. Etc.
