What is S355J2G3 Standard
The standard of S355J2G3 grade is EN10025-2. It is known for its excellent mechanical properties, including its high yield strength and tensile strength.
Differences between S355J2G3 and S355J2H
S355J2H and S355J2G3 are both grades of the steel material S355. However, there are slight differences between the two.
1. Concept:
S355J2H is a structural hollow section that is widely used in construction and engineering applications.
S355J2G3 is a normalized carbon steel that is used extensively for structural applications
2. Advantages:
S355J2H has good impact strength, toughness, and resistance to cyclic loading,
S355J2G3 has good welding and forming properties
3. Application:
S355J2H suitable for steel structures such as bridges, transmission towers, and buildings.
S355J2G3 suitable for use in welded structures.
4. Different means:
For S355J2H, the "H" in S355J2H stands for hollow section, indicating that it is a steel pipe with a hollow cross-section.
The "G3" in S355J2G3 refers to the fact that it is normalized, indicating that the steel has been subjected to a controlled heat treatment process to improve its properties.
LEFIN STEEL mainly produces the pipes with S355JRH, S355J0H and S355J2H standards.
Chemical properties of S355J2G3:
C ≤ 0.20
Si ≤ 0.55
Mn ≤ 1.60
P ≤ 0.035
S ≤ 0.035
J2G3 means that the delivery status is normalized, the impact energy at -20 ℃ is 27J, and the deoxygenation method is G3.
Advantages of S355J2G3:
1. High Strength: S355J2G3 has a high yield strength, making it suitable for heavy-duty applications and high-stress environments.
