Temperature has a great influence on the strength of the material, a242 type 1 steel channel. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.
Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than a242 type 1 steel channel, 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.
