Standard:GB /T 4171-2008
Scope of application:Comprehensive performance, welding performance and good low-temperature impact toughness, suitable for containers, vehicles, buildings, construction of the production of weathering.
Special Use:
weathering steel,The Characteristic of the alloy composition and weight percentage is 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 remaining is Fe and trace impurities . Mainly used for railway vehicles, bridges, towers, and other indefinitely exposure to the atmosphere. Include Cu.Mn.Si.Al of alloying,uncomplicated adjust contents of some trace elements for ordinary low carbon steel (Q235).don`t change the production process of Q235 steel under the condition, then produce economical weathering steel of good corrosion resistance, mechanical properties.
