Weather resistance and composition description of Fe235W steel plate

Application of Fe235W steel plate:
Weathering steel is used for some steel structures that are exposed to the atmosphere for a long time, such as railways, vehicles, bridges, and towers. It is mostly used to manufacture structural parts such as containers, railway vehicles, oil derricks, seaport buildings, oil production routes and containers containing hydrogen sulfide corrosive medium in chemical petroleum equipment.

The alloy composition and weight percentage of Fe235W steel plate are:
C: between 0.12 and 0.21, Si: between 0.2 and 2.0, Mn: between 0.7 and 2.0, S: not more than 0.036, P: not more than 0.034, Cu: between 0.10 and 0.40, Al: not more than 0.2
Others are Fe and trace impurities. Through the alloying of Cu, Mn, Si, Al, etc., and the simple adjustment of the content of some elements of ordinary low-carbon steel (Q235 steel), it can produce excellent atmospheric corrosion resistance without changing the production process conditions of Q235 steel.

Mechanical properties of Fe235W steel plate:
Tensile strength: greater than 360;
Yield strength: greater than 235;
Elongation: greater than 25.

Fe235W weathering steel:
Weathering steel, that is, atmospheric corrosion-resistant steel, is a low-alloy steel series between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. The weathering resistance of weathering steel is 2 to 8 times that of ordinary carbon steel, and the coating property is 1.5 to 10 times that of ordinary carbon steel. At the same time, it also has the advantages of rust resistance and air corrosion resistance, which can make structural parts anti-corrosion and prolong life, reduce thickness and reduce consumption, save labor and energy and other excellent features.
