Carbon steel mainly refers to the steel whose mechanical properties depend on the carbon content in the A514 Grade B steel material steel, and generally does not add a lot of alloy elements, sometimes it is also called ordinary carbon steel. Carbon steel refers to iron carbon alloy with carbon content of WC less than 2%. In addition to carbon, carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus. According to the content of phosphorus and sulfur, the carbon steel can be divided into ordinary carbon steel, high quality carbon A514 Grade B steel material steel, high quality steel and super quality steel.At the same time, the company operates a variety of products of related iron and A514 Grade B steel material steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained A514 Grade B steel material ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.The correct choice of billet type, section shape, size and weight are of great significance to A514 Grade B steel material 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 A514 Grade B steel material rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.As A514 Grade B steel material, alloy 400 is a kind of metal with good corrosion resistance, it shows good uniform corrosion resistance in the marine atmosphere. This is because alloy 400 can form a very thin and tough protective film. Uniform corrosion is one of the easiest forms of corrosion to deal with, because engineers can quantitatively determine the corrosion rate of metals and accurately predict the service life of metals.The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
