As industries demand stronger, more reliable, and cost-efficient metal components, ductile iron castings have emerged as the preferred choice for engineers and equipment manufacturers worldwide. Known for their combination of high strength, ductility, and machinability, grades like EN-GJS-450-10 and ASTM A536 80-55-06 have become industry benchmarks.
OMEJA CASTING, a top ductile iron foundry in China, specializes in producing precision ductile iron components that meet the most rigorous international standards and application demands.
Unlike traditional gray iron, ductile iron contains spheroidal graphite nodules that provide exceptional toughness and elasticity. This microstructure enables ductile iron castings to perform reliably under stress, impact, and vibration — characteristics vital for automotive, machinery, hydraulic, and construction applications.
Key advantages include:
High tensile strength and yield strength
Superior elongation and impact resistance
Excellent machinability and surface finish
Dimensional stability under thermal cycling
Long service life with minimal maintenance
In short, ductile iron bridges the performance gap between cast iron and steel — offering both economy and endurance.
At OMEJA CASTING, two of the most requested ductile iron grades are EN-GJS-450-10 (European standard) and ASTM A536 80-55-06 (American standard). Both deliver excellent mechanical performance tailored to different design needs.
Tensile Strength: ≥ 450 MPa
Yield Strength: ≥ 320 MPa
Elongation: ≥ 10%
Characteristics: Good balance of strength and flexibility, ideal for parts subjected to medium stress.
Applications: Valve bodies, pump housings, bearing supports, agricultural machinery.
Tensile Strength: ≥ 552 MPa (80 ksi)
Yield Strength: ≥ 379 MPa (55 ksi)
Elongation: ≥ 6%
Characteristics: High strength and fatigue resistance, suitable for heavy-duty mechanical applications.
Applications: Gears, couplings, flanges, brackets, and industrial fittings.
OMEJA CASTING offers both grades with customized metallurgical composition, ensuring the right balance between strength, ductility, and machinability for each project.
As one of China’s most trusted ductile iron foundries, OMEJA CASTING integrates modern casting technology with strict quality control to ensure consistent, high-performance results.
Our production capabilities include:
