GGG 35.3 steel grade is a new standard that offers enhanced durability and versatility compared to traditional steel grades. It has excellent mechanical properties and a specific chemical composition that contributes to its exceptional performance.
The mechanical properties of GGG 35.3 steel grade include:
1. Tensile strength: GGG 35.3 has a minimum tensile strength of 350 MPa, making it highly resistant to tensile forces.
2. Yield strength: The minimum yield strength of GGG 35.3 steel grade is 220 MPa, indicating its ability to withstand permanent deformation under load.
3. Elongation: GGG 35.3 exhibits a minimum elongation of 18%, which means it can undergo significant plastic deformation before failure.
4. Hardness: The steel grade has a Brinell hardness of 170 – 230 HB, indicating its resistance to indentation and wear.
The chemical composition of GGG 35.3 steel grade typically consists of:
1. Carbon (C): The carbon content ranges from 3.40% to 3.60%. Carbon increases the hardness and strength of the steel.
2. Silicon (Si): Silicon is present in the range of 2.20% to 2.60%. It improves the strength and elastic properties of the steel.
3. Manganese (Mn): The manganese content is limited to a maximum of 0.6%. Manganese contributes to the formation of ferrite, enhancing the strength and ductility of the steel.
4. Phosphorus (P): Phosphorus content is limited to a maximum of 0.1%. Excessive phosphorus can reduce the impact toughness of the steel.
5. Sulfur (S): The sulfur content is limited to a maximum of 0.03%. Higher levels of sulfur can lead to reduced ductility and brittleness.
6. Magnesium (Mg): Magnesium is typically present in trace amounts (less than 0.06%). It improves the machinability of the steel.
GGG 35.3 steel grade’s chemical composition and mechanical properties make it suitable for a variety of applications, including automotive and machinery components, structural parts, and engineering components that require high strength, durability, and resistance to wear and impact.
