Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

Hull structural steel is divided into general thickness and high-strength steel General strength steel is divided into four grades of A, B, C and D; high-strength steel is divided into two strength grades and three quality grades; AH32, DH32, EH32, AH36, DH36, EH36 In order to ensure quality and ensure sufficient toughness of hull structural steel, the chemical composition of Mn / C is required to be above 25, and the carbon equivalent is also strictly required Our Hull structural steel plates can be supplied with certificates from different classification societies,SA709 grade 50 carbon steel material.

The company attaches great importance to logistics services, sets up our own transport truck fleet, improves customer response capacity through the improvement of logistics capacity, and further reduces costs. Customers ordering steel from our company can not only enjoy the service of fast delivery, but also enjoy lower transportation costs. Fast, accurate, simple and efficient has always been our principle.

SA709 grade 50 carbon steel material,Quenching Improve the hardness of steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of steel and comprehensive mechanical properties.

After extrusion, the tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

SA709 grade 50 carbon steel material,Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.

In addition, according to customs statistics, from January to February, 7.81 million tons of steel were exported, 2.04 million tons of imported steel, and 6.01 million tons of net exported steel were converted into crude steel, a year-on-year decrease of 33.7%. According to the above data, the average daily supply of crude steel in China from January to February was 2478200 tons, down 5.09% from December of last year, up 3.70% year on year. Compared with the situation of delayed demand, steel production keeps growing, and the market presents a situation of supply exceeding demand.
