Sand Casting Parts Series 5
Designed for harsh chemical and mechanical environments, our High-Toughness Corrosion-Resistant Sand Casting Parts Series 5 offers a unique combination of fracture toughness and chemical inertness, ideal for components exposed to both corrosive media and dynamic loads. Cast from duplex stainless steel (ASTM A890 Grade 5A) and nickel-copper alloy (ASTM B127 Monel 400), these parts feature a ferrite-austenite microstructure and pass 2000h H2S testing, setting the standard for oil & gas, marine, and chemical processing applications.
Dual-Phase Material Advantage
Duplex Stainless Steel (2205):
Yield strength 550MPa, elongation 25%, and PREN (Pitting Resistance Equivalent Number) 40+, resisting chloride-induced pitting (ASTM G48 Method A, 24h at 6% FeCl3).
Monel 400:
Excellent resistance to hydrofluoric acid and seawater, with tensile strength 650MPa and impact toughness 80J/cm² (ASTM B127).
Casting Process Control
Low-Sulfur Molding Sand: Sulfur content ≤0.01% in mold materials, preventing hot cracking in nickel-based alloys (ASTM B164 compliance).
Post-Casting Heat Treatment: Solution annealing for duplex steel (1050°C, 1h) and stress relieving for Monel (595°C, 2h), optimizing corrosion and fatigue resistance.
Environmental Durability
H2S Resistance: Compliant with NACE MR0175 (SSC, HIC testing), suitable for sour gas environments (H2S partial pressure ≤3.5MPa).
Temperature Range: -196°C to 400°C, maintaining 90% toughness at cryogenic temperatures (ideal for LNG processing).
Surface & Design Features
Smooth Surface Finish: As-cast Ra ≤12.5μm, with optional electropolishing (Ra ≤0.5μm) to remove casting marks and enhance corrosion resistance.
Complex Design Support: Internal channels and thin walls (≥5mm) for heat exchanger components, validated by computational fluid dynamics (CFD) simulations.
Oil & Gas Industry:
Subsea pipeline valves, wellhead components, and Christmas tree parts, compliant with API 6A and ISO 13679 (NACE MR0175 Level II).
Marine Offshore:
Propeller shafts and seawater pumps, resisting biofouling and galvanic corrosion (ASTM G116 seawater immersion test).
Chemical Processing:
Agitator blades and reactor internals in pharmaceutical and petrochemical plants, compatible with aggressive solvents (e.g., benzene, toluene).
Corrosion Testing Leadership
In-house H2S/HCl exposure chambers (ASTM G31, G48) and electrochemical impedance spectroscopy (EIS) testing, providing detailed corrosion rate reports.
Alloy Expertise
Only sand caster offering Monel 400 parts with CT10 precision, supported by decades of experience in nickel-based alloy casting.
Regulatory Compliance
Certified to ISO 22309 (traceability), API Q1 (quality management), and Lloyd’s Register (marine applications), ensuring compliance in safety-critical sectors.
Life Cycle Support
Post-delivery material performance monitoring and failure analysis, helping customers optimize maintenance schedules (e.g., 5-year component life projections).
