The correct choice of billet type, section shape, size and weight are of great significance to SMA570W, SMA570P weather resistant steel steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The SMA570W, SMA570P weather resistant steel rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.
Heat treatment is a very important process to improve the performance of SMA570W, SMA570P weather resistant steel etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.
Since the beginning of this year, the global SMA570W, SMA570P weather resistant steel steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global SMA570W, SMA570P weather resistant steel steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
09CuPCrNi-A steel is weather resistant steel. It is also called 09CuPCrNi-A weathering steel, or 09CuPCrNi-A anti-corrosion steel. 09CuPCrNi-A steel is equivalent to SPA-H, Corten B, etc. steels. Compared with those steels, 09CuPCrNi-A steel price is cheaper while the performance is similiar. That is mainly because the demands for 09CuPCrNi-A steel is very large in China, which is one of the largest steel prodction and export country. So the production capacity of 09CuPCrNi-A steel in very large in China. Consequently, the unit cost of 09CuPCrNi-A steel is cheaper.
