Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than NM450 mechanical properties, ordinary carbon steel by adding less alloy elements. Q355GNH weathering steel has been widely used in container, railway vehicle, bridge, building and air preheater which need to be resistant to atmospheric corrosion. Q355GNH weathering steel is characterized by the addition of less Cu, P, Cr, Ni and other alloy elements in the steel, so that a dense amorphous spinel type oxide layer with a thickness of about 50-100μm is formed between the rust layer and the base metal, which can prevent oxygen and water from penetrating into the steel matrix, slow down the development of corrosion to steel materials, and improve the atmospheric corrosion resistance.

What are the characteristics of medium and thick plate, NM450 mechanical properties? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, NM450 mechanical properties is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.
