SM400 Structural Steel Plate

 

SM400 carbon structural steel plate has good impact toughness and plasticity, and can maintain good performance in harsh environments. At the same time, SM400 hot-rolled structural plate also has excellent weldability, which is convenient for welding processing.

 

In addition, SM400 low-carbon steel plate has a certain corrosion resistance after a specific smelting and heat treatment process, and can be used for a long time in harsh environments without rusting.

 

SM400 mild steel sheet application areas

Bridge construction: SM400 mild steel plate is used as the main load-bearing member of the bridge.

Construction engineering: SM400 hot-rolled mild steel plate is used to manufacture structural parts of high-rise buildings.

Shipbuilding: SM400 hot-rolled structural steel plate is also widely used in the field of shipbuilding, used to manufacture hulls, ship plates and other components.
