耐候鋼管概述：其特征在於：耐候鋼管的合金成分及重量百分比含量為：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、Al<0.2，其餘為Fe和微量雜質。通（tōng）過（guò）Cu、 Mn、Si、Al等合金化，並簡單調整普通低碳鋼(Q235鋼)的部分元素含量，在不需改變Q235鋼生產工藝條件下，就能生產出具有（yǒu）良好的耐大氣腐蝕性能、綜（zōng）合機械性（xìng）能的經濟耐候鋼管。
Summary of Weatherproof Steel Pipe: Characteristic: The alloy composition and weight percentage content of weatherproof steel pipe 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, Al < 0.2, the rest are Fe and trace impurities. Through alloying of Cu, Mn, Si and Al, and simply adjusting the element content of common low carbon steel (Q235 steel), economic weatherproof steel pipes with good atmospheric corrosion resistance and comprehensive mechanical properties can be produced without changing the production process of Q235 steel.
