Detailed introduction of Q345NH weathering steel plate

Q345NH weathering steel plate is a new type of alloy raw material. The reason is that copper, nickel, chromium, phosphorus and other components are added to Q345NH weathering steel plate to change the growth of the rust layer from the original sheet-like fluffy structure to the point-like dense structure, thereby blocking the growth of the rust layer. Air and water further erode the substrate.

1. Q345NH weathering steel plate is mainly used in the production of steel structure parts, bridges, ships and vehicles.

2. Q345NH weathering steel plate adds special elements (P, Cu, C, etc.), which has good corrosion resistance and atmospheric corrosion resistance. It is used in the production of special container vehicles and also used in building structures.

3. Q345NH weathering steel plate is a high-strength steel plate with good stamping performance and welding performance.

4. Q345NH weathering steel plate, hot-rolled special steel, carbon steel, alloy steel, tool steel for general mechanical structure, used in the production of various mechanical parts after thermal engineering.

5. Q345NH weathering steel plate is used to produce various cold-rolled products, including CR, GI, color-coated plates, etc.

6. Q345NH weathering steel plate for steel pipes has good performance and compressive strength, and is used to produce high-pressure gas pressure vessels filled with LPG gas and various gases with an internal volume of less than 500L.
