EN-GJS-500 Ductile Iron

EN-GJS-500 is a commonly used medium-to-high-strength ductile iron grade under European standards. It combines relatively high tensile strength with good toughness, wear resistance, and machinability. Compared with conventional gray cast iron, it provides better load-bearing capacity, impact resistance, and fatigue performance.

Appearance & Properties

Color: Dark gray to gray-black

Density: Approx. 7.0–7.2 g/cm³

Tensile Strength: Typically ≥500 MPa

Wear Resistance: Good

Machinability: Good

Toughness: Good

Fatigue Resistance: Good

Load-Bearing Capacity: Good

Magnetism: Magnetic

Surface Finishes: Painting, black oxide, phosphating, plating, grinding, etc.

Typical Applications

EN-GJS-500 Ductile Iron is widely used in automotive, construction machinery, industrial equipment, agricultural machinery, pumps and valves, and power transmission systems.

Typical parts include gears, wheel hubs, bearing housings, brackets, flanges, pump bodies, valve bodies, machine housings, and various high-load CNC-machined cast components.

Advantages

• Relatively high mechanical strength and load-bearing capacity

• Better toughness and impact resistance than gray cast iron

• Good wear and fatigue resistance

• Good machinability

• Suitable for complex, heavily loaded cast components

Limitations

• Relatively heavy and not ideal for lightweight designs

• Limited corrosion resistance and usually requires surface protection

• Poor weldability

• Lower strength than some high-strength alloy steels
