Stainless steel offers excellent biocompatibility, durability, and easy sterilization. It is ideally suited for manufacturing high-end medical instruments and equipment. QD provides safe and reliable stainless steel component solutions for global healthcare clients.
QD is the primary manufacturer and exporter of stainless steel medical devices. With over 20 years of casting experience, our medical equipment has been exported to more than 80 countries and is highly praised by clients.
Core Material Requirements for Medical Devices
Excellent Biocompatibility
Materials must not cause toxic or adverse reactions when contacting human tissues, blood, or bodily fluids. They must not induce sensitization, inflammation, or other negative responses.
QD strictly follows the regulatory requirements for medical device materials from major global market authorities. These include China’s NMPA, the US FDA, and the EU’s MDR. The medical-grade stainless steel we use complies with the ISO 10993 series standard for biological evaluation of medical devices.
Superior Corrosion Resistance
Medical devices frequently come into contact with disinfectants, saline solutions, blood, and various chemicals. They often operate in high-humidity environments.
QD’s austenitic stainless steels effectively resist pitting, crevice corrosion, and stress corrosion cracking. They ensure the device’s functional integrity and longevity under repeated chemical exposure. Their stable surface prevents corrosion products from flaking off. This avoids secondary harm to patients and prevents contamination of sensitive drugs or reagents.
Broad Sterilization Compatibility
Medical devices must withstand repeated and effective sterilization cycles to prevent cross-contamination.
QD’s stainless steel can undergo repeated cycles in autoclaves at 135°C without losing performance or deforming. It is also compatible with other sterilization methods, showing good resistance to mainstream low-temperature processes like gamma radiation and ethylene oxide.
Excellent Mechanical Properties
High Strength and Toughness: This ensures components like surgical instruments and orthopedic implant brackets do not deform or fracture under stress. It guarantees operational precision and safety.
High Fatigue Strength: Essential for reusable instruments or long-term load-bearing components, it provides high resistance to fatigue.
Dimensional Stability: It maintains its shape and size stability during both processing and use.
Applications of QD Stainless Steel in the Medical Industry
Surgical Instruments
General surgical instruments: such as surgical forceps, scissors, needle holders, and tissue forceps.
Orthopedic and dental instruments: including bone chisels, dental probes, and dental handpiece housings.
Medical Equipment
Hospital bed and surgical table components: such as lifting frames, joint connectors.
Medical equipment housings and support frames
Auxiliary Devices & Facilities
Sterilization and sterile storage systems: including sterilization containers, instrument trays, sterile storage cabinets.
Instrument carts and workstations
QD’s Production Process and Quality Assurance System
Strict Material Selection and Management
QD primarily uses austenitic stainless steel grades like 316L and 304. These provide excellent corrosion resistance and biocompatibility.
Full-process traceability is implemented. We maintain a traceability system covering all stages from raw material intake, production batches, to finished product shipment. Information for any step is clearly accessible.
Professional Processing Technology
For complex-shaped components, QD uses lost-wax precision casting and CNC finishing. This achieves near-net-shape forming while maintaining material integrity.
QD provides high-grade surface treatments including mirror polishing, electropolishing, and passivation. These treatments prevent bacterial adhesion and further enhance corrosion resistance.
QD team fully considers usage scenarios during the product design phase. We implement dead-space-free structural designs using smooth transitions, rounded edges, and minimized seams. This makes the final structure easy to clean and maintain.
Full-Process Quality Control
Key casting processes are completed in a cleanroom environment to prevent contamination during production.
QD provides a comprehensive inspection system including chemical composition analysis, mechanical property testing, non-destructive testing, and dimensional accuracy inspection.
Products undergo final cleaning and packaging in a controlled clean environment. We provide sterilization services according to client requirements. Each production batch comes with complete quality documentation.

FAQ
1. What is the fundamental difference between QD’s medical-grade and industrial-grade stainless steel?
The core differences are biocompatibility certification and full-process cleanliness control. Medical-grade stainless steel must pass strict biological safety evaluations like ISO 10993. Its entire production and packaging process must follow procedures that prevent chemical and microbial contamination. Industrial-grade steel does not require these.
2. Can QD provide materials for long-term implantable medical device components?
We supply precision components for manufacturing surgical tools, sterilization trays, or procedural aids that contact implants. However, we do not directly produce final products for long-term human implantation (e.g., bone screws, joints), as this requires medical device product registration. We act as your upstream precision component supplier.
3. How many sterilization cycles can QD products withstand?
This depends on the sterilization method and material grade. For example, 316L stainless steel can theoretically withstand unlimited standard autoclaving cycles without material degradation. The actual product lifespan depends more on structural design and mechanical wear.
4. How does QD ensure absolute surface cleanliness and sterility?
We achieve this through process control, not just final inspection. Our measures include: manufacturing in cleanrooms, using validated cleaning procedures, performing final passivation, and packaging in controlled environments. We can provide microbial load and bacterial endotoxin test reports for shipped products.
5. We have a structurally complex medical device component. Can QD produce it?
This is our core expertise. Precision casting is particularly suitable for producing complex, single-piece components. Please provide your CAD drawings. Our engineering team will conduct a manufacturing feasibility analysis and offer design optimization suggestions.
6. Does QD possess a medical industry quality management system certification?
Yes. QD Foundry has established and strictly enforces a quality management system that complies with ISO 13485 requirements for medical devices. We are actively progressing towards formal certification. This forms the foundation of our commitment to serving global medical clients.
