High Strength and Toughness:

Adopting EN-GJS-450-12 ductile iron material, tensile strength ≥450 MPa, yield strength ≥310 MPa, elongation ≥12%, it has excellent strength and toughness, and can withstand high loads and impacts in the exhaust system.

Excellent Wear Resistance:

The graphite in ductile iron is distributed in a spherical form, which significantly improves the wear resistance of the material and extends the service life of the exhaust pipe.

Good corrosion resistance:

Through reasonable material ratio and surface treatment (such as aluminum plating or ceramic coating), the corrosion resistance is improved to adapt to the humid and multi-chemical exhaust environment.

Fatigue resistance:

Ductile iron has good fatigue resistance and can maintain stable performance under high-frequency and high-load working conditions.

Efficient casting process:

Adopt molding line casting process (such as vertical molding line or horizontal molding line) to achieve efficient and mass production, ensuring product consistency and high quality.

Precision machining:

Use CNC machine tools for precision machining to ensure the dimensional accuracy and surface finish of the exhaust pipe, improve assembly accuracy and service life.

Lightweight design:

While ensuring strength, ductile iron exhaust pipe has a lighter weight, which helps to reduce the overall weight of the car and improve fuel efficiency.

3. Product advantages
