Among the many high-quality services MultiSource Manufacturing, LLC, provides with our network of facilities is the design and fabrication of medical device components. When it comes to manufacturing parts and components for medical devices, it’s critical to the health and safety of every patient across the world to establish extremely high standards for reliability, quality, and precision. MultiSource is dedicated to maintaining manufacturing practices that exceed standards for the medical device industry, including responsible materials-sourcing for all projects we take on. For many medical manufacturing projects, the parts and components require surgical-grade steel in order to fabricate the most reliable medical devices.
Surgical-grade steel is a nonspecific term for a variety of stainless steels used in the fabrication of many different tools, including most medical devices and other biomedical purposes.
The surgical steel utilized in most medical applications includes:
- Austenitic 316: This surgical steel is an alloy of nickel, chromium, and molybdenum that is highly resistant to corrosion and has adequate strength for medical devices and implants that are pressure-bearing. Alloys also used for pressure-bearing biomedical implants are typically titanium (Ti6Al4V, specifically), but the surgical steel 316 is also suitable, and it’s more economical than titanium.
- Martensitic 440 and 420: These steels are used for cutlery production, but they are also well suited for surgical-grade applications of the material. As high-carbon steels alloyed with chromium, 440 and 420 surgical-grade steels are very resistant to corrosion, though less so than 316. However, they are much harder than 316. Because they are harder than 316 but not as resistant to corrosion, 440 and 420 are often used to manufacture surgical implements and medical cutting tools.
The MultiSource network utilizes 316, 440, and 420 surgical-grade steels as well as a range of additional industry-approved and safely-sourced materials to fabricate many key components that go into a variety of medical devices. From surgical equipment to implantable devices, medical providers can rely on MultiSource to manufacture the highest quality parts and components that are the most reliable in the long term thanks to the materials used and the expertise of our fabricators.
Some of the more unusual and advanced medical manufacturing projects that we take on, like designing and producing parts for surgical navigation or ablation devices, benefit especially from our surgical-grade materials and our excellence in fabrication because of their unique complexities and relatively new introduction into medicine.
