Sell shipbuilding material Corten B railway steel in Qatar

Recently, a symposium on the celebration of the 70th anniversary of the founding of the People's Republic of China by the iron and steel industry was held in Beijing Convention Center. The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, BBN Corten B railway steel Steel Staff sang songs to the mark the 70th victory anniversary. In the last of September, Henan BBN Steel organized all employees to sing ""My Country and I"" and made a film.

The effect of nitrogen (N) on the properties of Corten B railway steel and so on steel is similar to that of carbon and phosphorus. With the increase of nitrogen content, the strength of steel can be significantly improved, especially the plasticity, especially toughness, and the weldability will be decreased, and the cold brittleness will be intensified. At the same time, aging tendency, cold brittleness and hot brittleness will be increased, which will damage the weldability and cold bending property of steel. Therefore, the nitrogen content in Corten B railway steel and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

Hardness comparison between Q345B steel and NM450 steel: wear resistant steel for construction machinery requires high wear resistance, high toughness, impact resistance, easy welding, easy forming and other high-performance characteristics. The main index of wear resistance is the surface hardness. The higher the hardness, the better the wear resistance. Compared with Corten B railway steel, Q345B steel, the hardness of NM450 steel is only increased 3 times, but the average service life is increased 6-8 times under the same working conditions.

The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve Corten B railway steel work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
