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.

Japan is a typical shipping first, and its raw materials are imported from Oceania, central and South America and other Asian countries. Most of the plate A573gr.70 high strength structural steel steel produced is exported to China and other Asian countries, and a small amount is exported to America. Shipping is the main way of its plate A573gr.70 high strength structural steel steel international transportation. According to the data, steel goods account for about 20% of the total sea freight in Japan. The domestic transportation of Japanese steel is mainly truck.

S355J2 steel plate plate A573gr.70 high strength structural steel rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the plate A573gr.70 high strength structural steel single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.
