Factory Custom Precision Duplex Stainless Steel Lost Wax Casting with Custom Thickness OEM/ODM Available Powder Coated

In advanced industrial manufacturing, precision duplex stainless steel lost wax casting stands as a premier method for producing components that demand exceptional strength, corrosion resistance, and design flexibility. Our factory specializes in custom precision casting services, offering tailored thickness options, comprehensive OEM/ODM collaborations, and high-quality powder coating finishes. This integrated approach ensures optimized performance for critical applications across marine, chemical, automotive, and energy sectors.

🛠️ Advanced Duplex Stainless Steel Materials

We utilize high-performance duplex stainless steel grades, with a typical composition including 22 % chromium, 5 % nickel, 3 % molybdenum, and 0.15–0.32 % nitrogen . This balanced microstructure of ferrite and austenite provides:

• High Strength & Durability: Yield strength ≥550 MPa, doubling that of conventional austenitic stainless steels, suitable for high-pressure environments.

• Superior Corrosion Resistance: Enhanced resistance to chloride stress corrosion cracking, ideal for marine and chemical applications.

• Custom Thickness Flexibility: Capability to produce thin-walled sections (e.g., below 3 mm) to thick-walled components, tailored to specific load and pressure requirements.

🏭 Precision Lost Wax Casting Process

Our lost wax (investment casting) process combines meticulous craftsmanship with modern technology to ensure dimensional accuracy and material integrity:

1. Pattern & Mold Creation: Precision wax patterns are injected using CAD-designed molds; ceramic shells are built via multi-layer stucco coating with silica sol binders.

2. De-waxing & Firing: Advanced autoclave systems remove wax, and molds are fired at 1100–1200 °C to achieve thermal stability.

3. Pouring & Finishing: Molten duplex steel is poured under controlled atmospheres; post-casting, components undergo CNC machining, heat treatment, and powder coating for enhanced aesthetics and corrosion protection.

💎 Key Performance Advantages

• Complex Geometries: Achieves intricate shapes, internal channels, and fine details with tolerances within ±0.005 inches/inch.

• Weight Reduction: Thin-wall capability (e.g., <3 mm) allows lightweight designs without compromising strength.

• Surface Quality: As-cast surfaces reach 125–250 µin Ra; powder coating adds uniform, durable finishes in custom colors, improving wear and chemical resistance.

• Cost Efficiency: Near-net-shape production minimizes material waste and secondary machining.

🎯 Quality Assurance and OEM/ODM Services

Our facilities are equipped with ISO 9001 certification and advanced labs for spectrochemical analysis, mechanical testing, and non-destructive inspections -9. We support OEM/ODM projects, collaborating closely with clients to adapt designs for manufacturability, optimize thickness, and select powder coatings for specific operational environments.

🚀 Industrial Applications

Custom duplex stainless steel castings are vital in:

• Marine & Offshore: Seawater piping, pump components, and valve impellers resistant to saltwater corrosion.

• Chemical Processing: Reactors, heat exchangers, and storage tanks handling corrosive media.

• Energy & Automotive: High-strength parts for turbines, exhaust systems, and hydraulic components.

• Architecture & Infrastructure: Structural elements and fixtures requiring durability and aesthetic powder-coated finishes.

By leveraging our custom precision duplex stainless steel lost wax casting services, industries gain access to components that excel in harsh conditions, reduce lifecycle costs, and accelerate innovation. Our commitment to tailored thickness, OEM/ODM flexibility, and premium powder coating ensures reliable, high-performance solutions for global engineering challenges.
