耐候無縫鋼管口述：其特點參加：耐候無縫鋼管（guǎn）的鋁合金本人成（chéng）分及量體重百分比容量（liàng）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，其它為Fe和少（shǎo）量廢物。借助Cu、 Mn、Si、Al等鋁合金化，並更為簡便作出調（diào）整普通低碳（tàn）鋼（gāng）(Q235鋼)的一部分（fèn）因素容量，在不需成為Q235鋼製造（zào）工藝具體（tǐ）條（tiáo）件下，就能生出現具備較好（hǎo）的耐空氣破壞使用性能、整體機械使（shǐ）用性能的經濟領域耐候無縫鋼管。
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.
