一、asic information of weathering steel
Weathering steel, also known as atmospheric corrosion resistant steel, the design concept behind it is to create a low-alloy steel by adding a specific amount of alloying elements to ordinary steel. This special steel has a wide range of application scenarios, and can be divided into two kinds of welding structure weathering steel and high weather resistance structural steel according to different characteristics, which can adapt to different application needs.
In terms of specifications, the thin steel plate used in weathering steel is a steel plate with a thickness of 0.2-4mm that is produced by hot rolling or cold rolling. The width of this thin steel plate is 500-
1400mm, because it has excellent wear resistance and strong toughness, so it can show its unique advantages in different application scenarios.
When faced with different use needs, thin steel plates are usually rolled from billets of different materials. For example, according to the characteristics of the thin steel plate in the production process, the materials usually used are carbon steel, excellent carbon steel, alloy structural steel, carbon tool steel, stainless steel, spring steel and electrical silicon steel. These different billet materials provide a rich choice for the production and application of weathering steel
At present, the world's largest producer of weathering steel is Germany, followed by China and Japan, accounting for two-thirds of the total global production of weathering steel. In the global market, the demand for weathering steel is dominated by the construction industry, especially large-scale projects such as high-end buildings, Bridges, Marine structures and steel structures
Weathering steel is a key application in railways, vehicles, highway Bridges, tower bodies, solar power generation, highway engineering projects, such as these persistent exposure in the air application of steel frame structure products. Weathering steel plays an important role in various segments of the industry, including the production of Marine containers, railway vehicles, crude oil derricks, port engineering buildings, oil extraction service platforms and chemical plant oil equipment components, which can also operate under conditions of sulfur content etched substances. In addition, weathering steel is also widely used in coal-fired power plants, coal farms, cement mills, loading equipment machinery, mining machinery, construction machinery, metallurgical engineering machinery and other fields, becoming an indispensable part of modernization.
Weathering steel characteristics: Weathering steel as a very high-quality special high-quality steel, contains excellent performance and powerful functions, it not only has excellent fatigue resistance, but also shows the excellent ability of high temperature resistance, and in the maintenance cost shows a significant low advantage, especially its strength, but also let people pay attention. Due to the excellent performance of weathering steel, it is widely used in many fields, such as photovoltaic power generation, road Bridges, railways, landscape architecture, power towers, containers and many other scenes, you can see the figure of weathering steel. Among them, the application of weather-resistant steel in the field of photovoltaic power generation, thanks to its excellent weather resistance and high temperature resistance, makes photovoltaic power generation equipment can operate more stably, thus greatly improving the efficiency of photovoltaic power generation. In the construction of highway Bridges, due to the high strength and excellent fatigue resistance of weathering steel, the safety and durability of Bridges can be guaranteed. In addition, in railway construction, weathering steel is also widely used in railway construction because of its characteristics of high temperature resistance, fatigue resistance and low maintenance cost. In landscape architecture, weathering steel with its unique appearance and excellent performance, has gradually become the preferred material for landscape architecture. In the construction of power tower, the advantages of weathering steel such as high temperature resistance, fatigue resistance and low maintenance cost make it an important material for the construction of power tower. At the same time, in the production of containers, weathering steel is also widely used because of its advantages of high temperature resistance, fatigue resistance and high strength. Therefore, from the application of weathering steel in various fields, it is widely used in many scenarios, and is deeply affected by the growth of downstream demand, which promotes the development of the industry.
