Understanding ASTM A536 Grade 80-55-06 Ductile Iron

ASTM A536 Grade 80-55-06 is a premium-grade nodular (spheroidal graphite) cast iron, combining high tensile strength with moderate ductility and excellent wear resistance.
Typical mechanical properties include:

Tensile Strength: 80 ksi (552 MPa)

Yield Strength: 55 ksi (379 MPa)

Elongation: 6% minimum

Hardness: 180–230 HB

This grade offers a balance of toughness and machinability, making it suitable for applications requiring structural integrity under stress and dimensional precision.

The material offers:

Excellent impact and fatigue resistance

High wear performance under dynamic loading

Stable dimensional accuracy after machining

Compatibility with surface treatments and coatings

Key Casting Products from OMEJA CASTING

1. Hose Fittings and Flexible Couplings

Precision-cast air hose connectors, quick couplings, and flexible hose ends are produced using ASTM A536 80-55-06 ductile iron. These components deliver excellent sealing performance, pressure resistance, and long service life in pneumatic and hydraulic systems.

2. Structural and Frame Connectors

The company manufactures key clamps and tube clamps widely used in fence systems, handrails, storage racks, and playground structures. These parts ensure stable mechanical strength and corrosion resistance under outdoor conditions.

3. Explosion-Proof Electrical Fittings

High-grade ductile iron castings are applied in industrial electrical housings for hazardous locations. ASTM A536 80-55-06 provides the strength and impact resistance necessary for explosion-proof enclosures and protective equipment.

4. Quick Couplings for Pipeline Maintenance

In cold and harsh regions such as Europe and Russia, OMEJA supplies pipeline repair couplings cast from 80-55-06 material. The grade’s mechanical stability ensures tight sealing and resistance to cracking under thermal cycling.

5. OEM Machined Castings

OMEJA offers custom cast iron parts based on customer drawings and functional requirements. Advanced sand and resin casting lines ensure consistent mechanical properties and smooth surfaces for machining and coating.
