What is S355 Steel Plate?

S355 steel plate is a very common type of structural steel. It is widely used in various construction and engineering projects. This type of steel plate has some excellent properties that make it highly favored in the industry.

Mechanical Properties of S355 Steel Plate

One of the important properties of S355 steel plate is its strength. It has a minimum yield strength of 355 MPa, which means it can withstand a certain amount of force without deforming permanently. In construction, for example, when building bridges or high - rise buildings, this strength is crucial. It can support heavy loads and ensure the safety and stability of the structures.

Ductility of S355 Steel Plate

S355 steel plate also has good ductility. Ductility refers to the ability of a material to be stretched or deformed without breaking. This property allows the steel plate to be shaped and formed into different structures easily during the manufacturing process. For instance, it can be bent into the required angles for making frames or supports.

Weldability of S355 Steel Plate

Another great property is its weldability. It can be welded effectively using common welding techniques. This is very important in construction projects where different parts of the steel structure need to be joined together. Good weldability ensures that the joints are strong and reliable, just like the rest of the steel plate.

Corrosion Resistance of S355 Steel Plate

Although S355 steel plate is not as corrosion - resistant as some specialized stainless steels, it still has a certain level of corrosion resistance. However, in some harsh environments, such as near the sea or in industrial areas with high pollution, additional protective measures like painting or galvanizing may be required to prevent corrosion and extend the service life of the steel plate.
