Weathering steel for welding structure is added a small amount of alloy elements to the steel, such as steel, chromium, nickel, molybdenum, niobium, titanium, zirconium and vanadium, to form a protective layer on the surface of the metal substrate. Therefore, this improve the corrosion resistance and has good welding performance. Weathering steel for welding structure is mainly used in bridges, buildings and other structures. Our company can supply weathering steel plate, sheet, strip and sections, SA588 gr A sizes with various shapes.
Compared with the traditional seamless steel pipe, alloy seamless pipe has better performance in all aspects. Because of the addition of various metal elements in the manufacturing, the overall strength of the alloy seamless pipe is larger, stronger and durable, and the service performance and service life of the SA588 gr A sizes, alloy seamless pipe are improved. The alloy seamless pipe is the best choice especially for special environment and high pressure requirements. Because of its high material properties, alloy seamless pipe has good corrosion resistance. It is not easy to be corroded in some special environment, which reduces the cost of the project and has a longer service life.
Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the SA588 gr A sizes plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.
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 SA588 gr A sizes 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 SA588 gr A sizes 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.
