Our prime quality high strength structural stel plates retain the acidic attacks in tough climatic environments. These steel plates are heat-treated at very high temperatures of the heat; further, these are cold and hot workable steel. Our plates and sheets have excellent superior weldability. A572 Gr.50 dual certified plates SMA400AW cold rolled weathering steel strip undergo many tests after the production such as corrosion test, pitting corrosion test, flattening test, flaring test, radiographic test and so on.
Steel plate SMA400AW cold rolled weathering steel strip cutting, according to different classification standards, there are different specific types. If it is divided by cutting temperature, it can be divided into cold cutting and hot cutting. One of the cold cutting, there are water jet cutting and abrasive cutting and so on, thermal cutting is flame cutting, plasma cutting and laser cutting. In addition, we also need to know that the high-grade thick SMA400AW cold rolled weathering steel strip steel plate can be cut by flame, and its cutting is as simple as that of ordinary low-carbon and low-alloy steel, but we need to pay attention to it.
In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe SMA400AW cold rolled weathering steel strip for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.
