Katalor, corten steel plate manufacturer, focuses on manufacturing and exporting Q355GNH corten steel plate, Q235NH corten plate, Q295GNH corten plate, s355j2wp, Q345NH corten steel plate and other S355J0W corten plates. Our corten plates are mainly used for railway, vehicle, bridge, tower, photovoltaic, high-speed engineering and other long-term exposure to the atmosphere.
Weathering steel is a low-alloy high-strength and atmospheric-resistant structural steel. It is also called corten steel. The main materials are: Q355GNH corten steel pipe, Q345NH corten steel plate, B480GNQR, 09CuPCrNi-A, S355J0WP, S355J2WP, S355J0W, S355J2W, Q235NH, Q295NH, Q355NH, Q355GNH, Q460NH, 295GNH, Q295GNHL, Q345GNH, Q345GNHL, 09CuPTiRE, WTst37-2.
The alloy composition and weight percentage of the Corten A steel are: C: ≤ 0.12, Si: 0.25 to 0.75, Mn: 0.2 to 0.5, S ≤ 0.02, P: 0.06 to 0.12, Cu: 0.25 to 0.5, Cr: 0.3 to 1.25, Ni: 0.12~0.65, the rest are Fe and trace elements. By alloying Cu, Mn, Si, Al or the like. Simple adjustment of the content of some elements of ordinary low carbon steel (Q235 steel), without changing the production process conditions of Q235 steel, can produce economic weathering steel with good atmospheric corrosion resistance and comprehensive mechanical properties.
Our reputation is based on quality, integrity, scientific management, continuous improvement of service purposes, customer first, service perfect, reputation first principle.
