A242 corten steel plates are resistant to atmospheric corrosion and are widely used in the construction industry. In the smelting process of A242 corten steel, adding trace weathering elements in molten steel to obtain corrosion performance. Although these weather elements can enhance the corrosion resistance of A242 corten steel, but also influent the performance of A242 corten steel with the change of smelting temperature and adding amount. So the smelting environment and adding amount need to go through strict control.
A242 corten steel is a kind of economic high strength low alloy steel that contains a small amount of alloying elements and has good corrosion resistance in atmosphere. Phosphorus is one of the alloying elements to improve corrosion resistance of steel. Usually when the content of phosphorus reached a certain level, A242 corten steel has a good corrosion resistance. Phosphorus is easy to form phosphorus segregation, "residual cold brittle", the qualitative analysis with the increase of phosphorus segregation behavior of A242 corten steel, and influence of niobium has certain theoretical guiding significance for developing Nb bearing A242 corten steel. With the increase of P content, strip organization became wider, more serious segregation; tempering after a certain period of time, with the increase of the tempering temperature is more and more serious segregation of phosphorus.
The above is the influence of phosphorus in smelting A242 corten steel under different conditions. If there is no good control of temperature, it will produce serious phosphorus segregation phenomenon. It is rather critically affect the performance of A242 corten steel.
