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
The virtual welding of JIS G3114 SMA 50 CP weathering steel plate hot melt butt welding is mainly caused by insufficient stroke of the butt welder fixture and too fast fixture speed during butt joint.
At the end of blowing, the silicon content in the molten steel is very low. In order to meet the silicon content requirements of EN10155 S355J0W steel plate, a certain amount of silicon must be added in the form of alloy material. In addition to being use
The operation of adding one or more alloying elements to the liquid steel of EN10155 S355J0W weathering steel plate to make it meet the requirements of the composition of the finished steel is called alloying. In most cases, deoxidization and alloying are
ASTM corten A weathering steel plate is often used in buildings, which means that ASTM corten A weathering steel plate has advantages when used as building materials. ASTM corten A weathering steel plate is not only strong but also stable.
High frequency quenching: put ASTM A588 Grade C weather resistant plate into high frequency electromagnetic coil, connect high frequency current, and then the product will produce induced current in the workpiece. However, the high frequency current is on
