USt37-2 carbon steel plate sheet equivalent din material

Q355NHE grade is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and E represents quality grade (A, B, C, D, E) composition. Q355NHE is an atmospheric corrosion-resistant steel plate, also called weather-resistant steel plate. It has the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature, and fatigue resistance.

What are the characteristics of medium and thick plate, USt37-2 carbon steel plate sheet? First, the performance of shock resistance and vibration is very good, so the application of medium and thick plates in buildings and bridges can greatly improve the safety. Second, the bearing capacity of medium and thick plate, USt37-2 carbon steel plate sheet is good, the performance is excellent. The bridge, the automobile girder steel plate, and buildings have strict load-bearing requirements, and it is easy to cause accidents if the steel materials not meet the requirements, so the selection of steel is more stringent.

As the thickness and hardness of USt37-2 carbon steel plate sheet increase, the tendency to crack at the cutting edge increases. In order to prevent the USt37-2 carbon steel plate sheet from cutting cracks, preheating should be carried out before USt37-2 carbon steel plate sheet cutting. Special attention should be paid to preheating to make the entire USt37-2 carbon steel plate sheet interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole USt37-2 carbon steel plate sheet cannot be preheated, the partial preheating method can be used instead.
