Hastelloy C-22 Hard Stainless Steel Medical Device Parts Precision Milling Processing
This service is dedicated to the fabrication of critical, high-integrity components for medical devices that must operate reliably in the most corrosive and demanding physiological or chemical environments.
Long-Term Implantable Devices: Structural frames, housings, and connectors for cardiac pacemakers, neurostimulators, implantable drug pumps, and cochlear implants that are exposed to aggressive bodily fluids and must resist biocorrosion for decades.
Surgical Instruments for Aggressive Chemotherapy: Components for oncology biopsy tools, surgical staplers, and laparoscopic instruments used in procedures involving cytotoxic agents, where residual chemicals could rapidly degrade standard materials.
In-Vitro Diagnostic (IVD) Equipment: Critical fluidic components, valve bodies, and sensor housings in blood analyzers, DNA sequencers, and laboratory automation systems that handle corrosive reagents, acids, and halides.
Pharmaceutical Processing Equipment: Wear parts, tooling, and fixtures used in the manufacture of highly acidic or alkaline pharmaceuticals, where material purity and corrosion resistance are paramount.
We provide advanced precision CNC milling services specifically for Hastelloy C-22 (UNS N06022), a premier nickel-chromium-molybdenum-tungsten alloy. This material is selected for applications where "universal" corrosion resistance—to oxidizing and reducing media, pitting, crevice, and stress corrosion cracking—is non-negotiable. Machining this hard, work-hardenable superalloy requires specialized expertise in tooling, cutting parameters, and fixturing to achieve the required dimensional accuracy and surface integrity without inducing excessive stress or micro-cracks. Our process is optimized to produce complex, high-tolerance geometries such as thin-walled enclosures, intricate channels, and precision mounting features. Each component is meticulously finished and treated to restore the alloy's maximum inherent corrosion resistance, ensuring it meets the extreme longevity and reliability standards of cutting-edge medical technology.
| Category | Parameter | Details / Specification |
|---|---|---|
| Base Material | Alloy Designation | Hastelloy® C-22 / UNS N06022 / W.Nr. 2.4602 |
| Material Standard | Conforms to ASTM B575 (Sheet/Plate), ASTM B574 (Bar). | |
| Key Characteristics | Exceptional resistance to a wide spectrum of corrosive chemicals (including chlorides, wet chlorine, hot contaminated acids). Excellent biocompatibility and thermal stability. | |
| Machining Capability | Primary Process | Multi-Axis (3+2, 5-Axis) Precision CNC Milling. |
| Machining Difficulty | High. Requires rigid machine tools, specialized carbide tooling, high-pressure coolant, and optimized parameters to control work-hardening and heat generation. | |
| Achievable Geometries | Complex 3D contours, deep cavities, thin ribs (down to ~0.5mm), precision bores, undercuts, and fine surface details. | |
| Precision & Tolerances | Standard Dimensional Tolerance | ±0.025 mm (±0.001") on critical machined features. |
| High-Precision Tolerance | ±0.0125 mm (±0.0005") achievable for select features with controlled processes. | |
| True Positional Tolerance | Can be held within 0.05 mm or better for mating features. | |
| Surface & Finish | As-Machined Finish | Typically Ra 0.8 - 1.6 µm (32 - 63 µin). Can be improved with fine milling strategies. |
| Critical Post-Process | Electropolishing (Preferred) or chemical passivation (per ASTM A967) is mandatory after machining to remove surface contaminants, smeared metal, and restore the optimal passive oxide layer for maximum corrosion resistance. | |
| Post-Process Finish | Electropolishing can achieve Ra < 0.4 µm (16 µin) and a bright, clean surface. | |
| Quality Assurance | Material Certification | Full traceability with Mill Test Certificate providing chemical analysis and mechanical properties. |
| Inspection | 100% critical dimension verification using CMM. Surface inspection for defects. First-article inspection reports (FAIR) provided. | |
| Cleanliness | Post-machining cleaning per medical device protocols. Cleanroom packaging available. | |
| Compliance | Quality System | Manufactured under a Quality Management System compliant with ISO 13485. |
| Biocompatibility | Material is inherently biocompatible. Final device biocompatibility is subject to assembly and final product validation. |
