G35 Steel Grade: The Future of Construction and Manufacturing

Specification of G35 Steel Grade: The Future of Construction and Manufacturing

G35 steel grade is a high-strength structural steel that is commonly used in the construction and manufacturing industry. It offers excellent mechanical properties and a favorable chemical composition, making it suitable for various applications.

Mechanical Properties of G35 Steel Grade:

1. Tensile Strength: G35 steel grade has a minimum tensile strength of 550 MPa, ensuring its ability to withstand high loads and stresses.

2. Yield Strength: The minimum yield strength of G35 steel grade is 355 MPa. This property indicates its ability to resist deformation and maintain its shape under load.

3. Elongation: G35 steel grade has a minimum elongation of 22%, meaning it can stretch without breaking, providing flexibility in construction and manufacturing processes.

4. Impact Resistance: G35 steel grade exhibits excellent impact resistance, allowing it to absorb energy without fracturing or cracking under sudden loads or impacts.

5. Hardness: G35 steel grade has a hardness range of 180-240 HB, representing its ability to resist surface wear and abrasion.

Chemical Composition of G35 Steel Grade:

1. Carbon (C): The carbon content in G35 steel grade is typically around 0.25%, providing enhanced strength and hardness.

2. Manganese (Mn): G35 steel grade contains manganese ranging from 1.20-1.60%. Manganese improves the steel’s toughness and hardenability.

3. Silicon (Si): The silicon content in G35 steel grade is limited to 0.35%, which promotes steel’s strength and corrosion resistance.

4. Phosphorus (P) and Sulfur (S): The maximum phosphorus and sulfur content in G35 steel grade are 0.040% and 0.050%, respectively. These elements are controlled to ensure good weldability and machinability.

5. Chromium (Cr): G35 steel grade may contain up to 0.30% chromium. Chromium enhances the steel’s corrosion resistance and improves its hardenability.

6. Other Alloying Elements: G35 steel grade may also include small amounts of other alloying elements like nickel (Ni), copper (Cu), and molybdenum (Mo) to further enhance its properties.

In conclusion, G35 steel grade is a high-strength structural steel with excellent mechanical properties and a carefully balanced chemical composition. Its versatility and durability make it a promising material for the future of construction and manufacturing industries.
