How to judge the real weathering steel plate?

With the continuous development of economic level and the continuous improvement of comprehensive national strength, weathering steel industry has also been a rapid development, so how much do you know about weathering steel? Next, we will simply analyze it for you.

Weathering steel plate has good corrosion resistance, and its application range is also very wide, can be used in the manufacture of railway vehicles, oil derrick, containers and buildings around the harbor, because the weather resistant steel plate has a very good corrosion resistance, the application range is relatively wide.

But in the selection of weathering steel, also pay attention not to buy fake, so how to identify it? According to its non rusting stage, but the naked eye is unable to distinguish the weathering steel plate from the ordinary hot-rolled steel plate, and according to the inspection organization, whether the metal composition matches the warranty can be detected.

Generally speaking, if the steel plate is outdoors for one to three months, there will be small rust spots. The rust spots of ordinary steel plate are relatively loose, some of them are embroidered, and the relatively poor treatment will lead to the phenomenon of peeling off.

If the steel plate is outdoors for four to eight months, the rust water of weathering steel is less, and the rust spots are small and thick. If it is ordinary steel plate, there is more rust water. If the steel plate is outdoors for more than eight months, there will be clear and dense rust core layer, which can hardly be removed by hand. The rust of ordinary steel plate is more, and even the whole rust skin peels off When buying, be sure to judge carefully.
