First of all, to introduce you to the chemical elements of weathering steel: C: 0.12 ~ 0.21 below, Si: 0.2 ~ 2.0 below, Mn: 0.7 ~ 2.0, S ≤ 0.036, P ≤ 0.034 below, Cu: 0.10 ~ 0.40, aluminum < 0.2 , the rest is Fe and trace impurities. Through Cu, Mn, Si, Al and other alloying, and simply carry out the adjustment of the enterprise ordinary low carbon steel (Q235 steel) part of the design element content, without changing the Q235 steel production and processing process development conditions, it can improve the production company out with good resistance to atmospheric environmental corrosion performance, comprehensive use of mechanical system performance of economic weathering steel. However, for something it is always a with the following two different sides, also has a lot of advantages and disadvantages, for weathering steel plate is its advantages and disadvantages dialectical view, and therefore can be selectively applied, so what are the advantages and disadvantages?
