The alloy composition and weight percentage content of Q235NH steel are: C: 0.12 to 0.21, Si: 0.2 to 2.0, Mn: 0.7 to 2.0, S ≤ 0.036, P ≤ 0.034, Cu: 0.10 to 0.40, Al <0.2, and the rest is Fe And trace impurities. Through alloying of Cu, Mn, Si, Al, etc., and simple adjustment of some element content of ordinary low carbon steel (Q235 steel), it can produce good atmospheric corrosion resistance without changing the production process conditions of Q235 weathering steel with comprehensive mechanical properties.

Q235NH weathering plate refers to a low-alloy structural steel with a protective rust layer and atmospheric corrosion resistance, which can be used to manufacture steel structures such as vehicles, bridges, towers, and containers. Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only a small amount of alloying elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc. The total amount of alloying elements is only a few percent, unlike stainless steel, which reaches 100%. Ten percent, so the price is relatively low.
