The
characteristics of weather-resistant steel plate refer to low-alloy steel with maintenance rust layer and air erosion resistance, which can be used to produce steel frame structures such as cars, road bridges, towers, and shipping containers. Compared with ordinary carbon steel, weather-resistant steel plate has better corrosion resistance in the air. Compared with stainless steel plates, weather-resistant plates can only analyze aluminum alloy elements in trace amounts, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc., weather-resistant plates, aluminum alloy elements account for only a few percent of the total output , Unlike the stainless steel plate, more than ten percent, so the price is relatively cheap. The alloy composition and net weight percentage water content of Weather-resistant steel plate are: 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.
Weather-resistant steel plate production and processing: show laser cutting, electric welding and welding forming, piercing, hollow carving, engraving, sheet metal bending, and finished products can be made according to engineering drawings.
First, the weather-resistant steel plate has outstanding visual appeal. Weather board will change with time. Its color brightness and contrast are higher than ordinary building materials, so it is very easy to show out under the background map of green plants in the garden landscape. In addition, the matte surface caused by the rust of the thick steel plate makes the building more volume and quality.
Second, the weather-resistant steel plate has a strong ability to shape the body. Like other metal composite materials, weather-resistant panels can easily be shaped into a colorful and transformative look, and can maintain a good comprehensiveness, which can not be exceeded by wood, marble and their concrete.
Third, the Weather-resistant steel plate also has a unique ability to define indoor spaces. Because the compressive strength and toughness of the Weather-resistant steel plate are quite large, it is not as much as the thickness limit of the diamond raw material due to the structure. Therefore, it is possible to use too thin weather-resistant panels to separate the indoor space very clearly and accurately, making the place more and more concise and brisk, and filled with energy.
In the early stage of the Weather-resistant steel plate, the rust layer transformed from the surface layer is denser than that of the carbon steel, and the relative cracks and holes are less; after 25 days, the carbon steel and the weather-resistant steel plate have a layered condition, and there is no difference in the erosion material. The key is the effect of aluminum alloy elements in the rust layer. The rust layer of weather-resistant steel plate has the dissolution of Cu and Cr aluminum alloy elements, which can resist the intrusion of water vapor in the air and harmful ionization, and avoid further erosion of conventional metal materials. It exceeds the effect of air erosion resistance!
