Material: 45 # steel plate, 42CrMo steel plate, Q235B steel, 10# steel plate, 20# steel plate, 45 # steel plate, 16Mn steel plate, 45Mn steel plate, 50Mn steel plate, 65Mn steel plate, 60si2mn steel plate, Q345A steel plate, Q345B steel plate, Q345C steel plate, Q345D steel plate, Q345E steel plate, 20Cr steel plate, 35Cr steel plate. Our steel plates have high demand in several applications thus we are a popular name of the steel product market.

The effect of nitrogen (N) on the properties of S690QL material specification 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 S690QL material specification and so on steel should be reduced and limited as much as possible. Generally, nitrogen content should not be higher than 0.018%.

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 S690QL material specification 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.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of S690QL material specification, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.
