Stainless Steel Investment Casting Services High Precision Parts

Key Benefits of Stainless Steel Investment Casting

When you need components that survive extreme environments while maintaining surgical precision, our stainless steel investment casting is the ultimate solution. We focus on delivering near net shape casting to save you significant time and material costs.

Why Choose Precision Investment Casting?

• Unmatched Durability: Our stainless steel cast parts offer superior resistance to both oxidation and corrosive chemicals.
• Tight Tolerances: We maintain exceptional accuracy (±0.005 in/in), often eliminating the need for expensive secondary machining.
• Design Freedom: We easily produce intricate geometries and thin-walled sections that are impossible with traditional sand casting.
• Surface Excellence: Achieve smooth, professional finishes (125-250 RMS) directly from our specialized ceramic shells.

Performance Advantages Overview

By utilizing the lost wax casting stainless steel process, we ensure your components are ready for service faster, providing the structural integrity and “near-net” precision your application demands.

Common Stainless Steel Alloys and Grades

We select specific alloys based on how your part needs to perform in the real world. Whether you need corrosion resistant castings for marine environments or high-strength components for industrial machinery, choosing the right material is the foundation of a successful project.

Austenitic Stainless Steel (300 Series)

These are our most popular options for 304 stainless steel casting and 316L stainless steel investment casting. They offer the best corrosion resistance and are non-magnetic.

• 304/304L: The standard “18-8” stainless. Excellent for food processing and general industrial use.
• 316/316L: Contains molybdenum for superior resistance to chlorides and chemicals. Check out our 300 series stainless steel grades properties guide for a deeper dive into these versatile materials.

Martensitic and Precipitation-Hardening (PH) Alloys

When your application demands high hardness and mechanical strength, we turn to martensitic grades.

• 17-4 PH stainless casting: A favorite for aerospace and defense because it combines high strength with decent corrosion resistance.
• 410 & 420 Grades: These are heat-treatable alloys used when wear resistance is the top priority, such as in valve internal parts or cutlery.

Duplex and Specialized Alloys

For the most aggressive environments, duplex stainless steel casting provides a mix of austenitic and ferritic structures. This results in nearly double the strength of standard austenitic grades and incredible resistance to stress corrosion cracking.

Our stainless steel foundry services include spectrographic analysis on every heat to ensure the chemical composition of your stainless steel cast parts meets ASTM and industry standards perfectly. We focus on delivering near net shape casting that minimizes your machining time while maximizing material performance.

At Vastmaterial, our stainless steel investment casting workflow is designed to deliver near net shape casting with extreme accuracy. We utilize a refined stainless steel casting process that eliminates the need for heavy secondary machining, saving you time and material costs.

Step-by-Step Lost Wax Casting Stainless Steel

• Wax Pattern & Assembly: We inject wax into precision molds to create an exact replica of your part. These patterns are assembled onto a central runner to create a “casting tree.”
• Ceramic Shell Building: The assembly is dipped into high-grade ceramic slurry and coated with refractory sand. This process is repeated several times to create a durable, heat-resistant shell.
• Dewaxing and Preheating: We use a flash-fire or steam autoclave to melt out the wax, leaving a perfect negative cavity. The shells are then preheated to ensure the metal flows smoothly into thin walls.
• Precision Pouring: Molten investment cast alloys, such as 304 or 316L stainless steel, are poured into the shells under strictly controlled temperatures.
• Knockout and Cutoff: Once cooled, we vibrate or water-blast the ceramic shell away. The stainless steel cast parts are then cut from the tree.
• Finishing & Inspection: Each part undergoes gate grinding, sandblasting, and necessary heat treatments. Our quality team performs spectrographic analysis and NDT testing to ensure every piece meets your exact specs.
