What is the value of p355gh steel yield strength

Pageviews:

Low alloy steel plate, refers to the steel plate whose alloy content is less than 3.5%. The most popular low alloy steel plate is P355GH steel, Q345B plate and its equivalent materials such as S355JR, A572 grade 50 and so on. Low alloy steel plate plays an important role in the construction, it must have enough strength and stability to bear the safety of the house. Low alloy steel plate is often used in large buildings with large bearing capacity and good cross-section stability, such as bridges, ships, lifting and transportation machinery, etc.

The bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. The bridge steel plate is required to have high strength and toughness, bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate p355gh steel should also have good welding performance and low notch sensitivity. If you want to have a more comprehensive and detailed understanding of bridge steel plate, welcome to visit our official website for consultation.

As the thickness and hardness of p355gh steel increase, the tendency to crack at the cutting edge increases. In order to prevent the p355gh steel from cutting cracks, preheating should be carried out before p355gh steel cutting. Special attention should be paid to preheating to make the entire p355gh steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole p355gh steel cannot be preheated, the partial preheating method can be used instead.
