EN 1.0545 (S355N) Steel

 

S355N is a normalized structural steel, and the standard it follows is EN 10025-3:2004. The chemical composition range of this steel type is as follows:

- Carbon content range: ≤0.20%

- Silicon content range: ≤0.50%

- Manganese content range: 1.50-1.70%

- Phosphorus content range: ≤0.025%

- Sulfur content range: ≤0.025%

- Copper content range: ≤0.55%

- Chromium content range: ≤0.30%

- Nickel content range: ≤0.50%

- Molybdenum content range: ≤0.10%

- Vanadium content range: ≤0.12%

 

The tensile strength of S355N is 470-630 MPa, yield strength is 355 MPa, and elongation at break is 22%. This means it has moderate strength and high toughness.

 

S355N normalized structural steel is suitable for multiple fields including building structures, bridges, ships, machining and petrochemical industries. In these fields, a steel material with moderate strength and high toughness is required to ensure the structural and safety performance of components.

 

Normalization treatment is a process of heating the steel to an appropriate temperature and then cooling it rapidly. Normalization treatment can improve the strength and hardness of the steel, while maintaining good weldability and toughness. This makes S355N normalized structural steel more durable when dealing with a large amount of stress and thermal deformation.

 

The advantages of S355N normalized structural steel include:

- Moderate strength: It has moderate strength, suitable for various engineering applications.

- Good toughness: Toughness refers to the ability of materials to resist fracture, and S355N normalized structural steel has high toughness.

- Good weldability: This steel material is easy to weld and can be welded using various different welding processes.

- Good processability: S355N normalized structural steel can be formed and processed by various processing methods.

 

The disadvantages of S355N normalized structural steel include:

- Relatively high cost: Production cost is relatively high due to moderate strength and demanding special chemical composition.

- Low solubility: In the heating process, intergranular embrittlement may occur, leading to a decrease in the toughness of the steel.

 

Common forms of S355N normalized structural steel include steel plates, steel pipes, shaped steel and steel materials, etc. These steel materials can be customized and processed according to requirements to meet the specific needs of projects or components.

 

S355N normalized structural steel has different comparison grades in different countries. For example:

- Chinese standard: Q345E

- American standard: ASTM A572 Grade 50

- Japanese standard: SM490

 

In conclusion, S355N normalized structural steel is a steel material with moderate strength and high toughness, which has a wide range of uses and good processability. It is widely used in construction, bridges, ships and other fields to bear medium loads and thermal deformation. Despite some disadvantages, its strength and toughness advantages make it still widely used in various fields.
