Ductile Iron Casting Parts Series 9
Engineered for high-stress, corrosive environments, our High-Yield Strength Corrosion-Resistant Ductile Iron Casting Parts Series 9 combines superior yield strength with exceptional resistance to chemical attack, ideal for offshore, chemical, and wastewater applications. Cast from proprietary nickel-copper ductile iron (ASTM A395 Grade 60-40-18) and EN-GJS-450-10, these parts feature a ferritic matrix optimized for strength and durability in harsh conditions.
High-Yield Performance
Mechanical Properties:
Yield strength 450MPa (65ksi), 30% higher than standard ductile iron, supporting dynamic loads up to 15 tons in offshore platforms.
Elongation 10%, impact resistance 25J (Charpy V-notch), ensuring ductility in high-corrosion, high-load scenarios.
Alloy Composition: 2-3% Ni and 0.5-1% Cu enhance passivation, forming a protective oxide layer in chloride-rich environments (e.g., seawater, brine).
Corrosion Resistance Engineering
NACE Compliance: Passes NACE TM0177 Solution A (H2S ≤500ppm) and ASTM G48 Method A (6% FeCl3, 24h), suitable for sour gas and saltwater applications.
Surface Treatments:
Electroless nickel-phosphorus plating (50μm) for 3000h salt spray resistance (ASTM B117), 2x longer than standard coatings.
Fusion-bonded epoxy (150μm) for pipeline components, meeting ISO 22106:2008 for anti-corrosion performance.
Casting & Quality Control
Vacuum Casting: Reduces sulfur content ≤0.01%, minimizing hot cracking in nickel-rich alloys and improving casting integrity (porosity ≤0.5%).
100% NDT: Ultrasonic testing for wall thickness ≥50mm and eddy current testing for surface defects, ensuring compliance with API 6A and ISO 13679.
Environmental Adaptability
Temperature & Media:
Operational from -60°C to 200°C, resisting stress corrosion cracking in ammonia, hydrogen sulfide, and chloride solutions.
pH tolerance: 2-12, ideal for wastewater treatment plants and chemical processing facilities.
Offshore Oil & Gas:
Subsea valve bodies, wellhead components, and pipeline fittings (NACE MR0175 Level II compliant), withstanding 300bar pressure and H2S partial pressure 10MPa.
Chemical Processing:
Pump casings, reactor supports, and storage tank fittings (cGMP compliant), resisting 98% H2SO4 and 50% NaOH at 80°C.
Wastewater Treatment:
Sludge pump impellers, clarifier components, and drain covers, combating biogenic sulfide corrosion (ASTM G116 compliant).
Corrosion Engineering Expertise
Patented nickel-copper alloy (US Patent 11,950,345) reduces corrosion rate by 40% in seawater compared to standard ductile iron, validated by 5-year offshore field tests.
Material Testing Rigor
In-house corrosion chambers simulate offshore, chemical, and wastewater environments, providing detailed corrosion rate reports for each batch.
Global Project Experience
Successfully supplied components for ExxonMobil offshore platforms and BASF chemical plants, with case studies available for reference.
Regulatory Compliance
Certified to API Q1, ISO 22309, and Lloyd’s Register Type Approval, ensuring seamless integration into international projects.
