Corrosion resistance: A lot of bridge design is close to the surface, some even cross-sea bridge, both the sea and the river, how much will appear high tide phenomenon, thus to drown of bridge deck, this material have higher requirements for bridge, if us
During the welding process, the UNI Fe 510 C2K1 weathering steel plate butt joint weld toe was repaired and (annealed). The microstructure, mechanical properties and residual stress after welding were compared and analyzed. The results showed that the wel
Weathering steel: classification of weathering structural steel, weathering grade, production method and weathering use. high weathering steel: hot rolled, high weathering steel grade: Q295GNH Q355GNH high weathering steel use, used in vehicles, container
JIS G3114 SMA 50 CP weathering steel plate has the characteristics of rust resistance, corrosion resistance and longevity of components, thinning and consumption reduction, and labor and energy saving. JIS G3114 SMA 50 CP weathering steel plate are mainly
The first can look at the quality of Q235NH weathering steel from the appearance, look at the appearance of the steel plate is not smooth enough lubrication, flatness or lubrication better steel plate quality is also better.
choose better Q345NH weathering steel quality. The wear resistance and toughness of Q345NH weathering steel can be significantly improved by adding special alloying elements into ordinary high-speed tool steels.
First of all, check whether there is a problem with the laser output, and whether the light spot is very round (the transverse distribution of the laser energy is uniform, and the cutting quality of the ASTM A588 Grade C weathering steel plate is good)
ASTM Corten A weathering steel plate is mainly used in highway and bridge engineering construction. Because of the corrosion-resistant aluminum alloy element, it has excellent air corrosion resistance compared with ordinary bridge steel. Thickness ≤150mm
First, At the stage when the steel plate is not long rusted, the naked eye cannot distinguish between ASTM A242 Type1 weathering steel plate and ordinary hot-rolled steel plate. It is necessary to refer to the steel mill’s warranty. The warranty requires
During the storage, transportation or processing of SEW087 WTSt 37-3 weathering steel plate, the surface of SEW087 WTSt 37-3 weathering steel plate is often stuck with oil stains or partially etched. Generally speaking, there is no way to remove it after
