S275NL Steel Grades

 

S275NL is a normalized structural steel with a standard of EN 10025-3:2004. The chemical composition range of the steel is:

- Carbon content range: 0.18%

- Silicon content range: ≤0.50%

- Manganese content range: 0.65-1.10%

- Phosphorus content range: ≤0.025%

- Sulfur content range: ≤0.020%

- Copper content range: ≤0.55%

- Chromium content range: ≤0.30%

- Nickel content range: ≤0.50%

- Vanadium content range: ≤0.12%

 

The tensile strength of S275NL is 430-580 MPa, the yield strength is 275 MPa, and the elongation at break is 22%. This means that it has moderate strength and high toughness characteristics.

 

S275NL normalized structural steel is suitable for many fields, including machinery, buildings, ships, and petrochemical equipment. In these fields, steel with moderate strength and high toughness is required to ensure structural and safety performance.

 

Normalization is a treatment process of heating 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 S275NL normalized structural steel suitable for stress under high pressure and high temperature environments.

 

The advantages of S275NL normalized structural steel include:

- Moderate strength: It has a moderate level of strength suitable for a variety of engineering applications.

- High toughness: Toughness refers to the ability of a material to resist fracture. S275NL normalized structural steel has high toughness.

- Weldability: This steel is easy to weld and can be welded with various different welding processes.

- Processability: S275NL normalized structural steel is easy to shape and process.

 

The disadvantages of S275NL normalized structural steel include:

- Relatively high cost: Due to its moderate strength and special chemical composition, the production cost is relatively high.

- Hydrogen embrittlement: In the heat treatment process, the material is susceptible to absorbing hydrogen, leading to brittle cracking.

 

The common forms of S275NL normalized structural steel include steel plates, steel pipes, I-beams, and steel bars. These steel materials can be diversified and customized according to specific project or component requirements.

 

S275NL normalized structural steel has some comparable grades in different countries, such as:

- Chinese standard: Q275Z

- American standard: ASTM A36

- Japanese standard: SS540

 

Overall, S275NL normalized structural steel is a steel with moderate strength and high toughness suitable for various engineering application scenarios. Despite its drawbacks, its advantages of toughness and weldability make it still widely used in various fields.
