MATERIALS
Stainless steel for precision bar turning of medical and dental products
The materials used by Polydec SA for the medical and dental industries can be separated into two main categories:
1) Stainless steel and alloys for medical and dental implants
- Austenitic steel: 316LVM (1.4441)
With a smooth, shiny surface, but heavier than titanium, 316LVM is also resistant to corrosion. This metal is often used in the medical sector. As a rule, 316LVM is well tolerated by the body and can even be sterilised.
Also called "surgical steel", it is often used to manufacture implants or ancillary parts. It is formed from various materials, including nickel, to which some people are allergic. To limit nickel release as much as possible, the 316LVM material is remelted several times so that it melts and blends with the other components. This process significantly reduces the risk of allergies. - Titanium
Titanium is a material that is mainly appreciated for its low density, its lightness and its solidity. As a rough comparison, it is around twice as light as steel yet has the same resistance and greater flexibility.
These days, titanium is very widely used in the medical industry because its protective layer makes it extremely resistant to corrosion. Its excellent resistance to attack from bodily fluids also makes it the most bio-compatible of all metals. It is widely used in surgery, especially for implants, since it is a material that is easily assimilated by the body.
2) Stainless steel for medical and dental instruments and appliances (in accordance with standard F 899)
- Ferritic steel
416 (1.4005), 430F (1.4104) - Martensitic steel
420F (1.4021), 420 (1.4028-1.4034), 431 (1.4057), 440B (1.4112), 440C (1.4125), 420MOD (1.4123), 630 (1.4542) - Austenitic steel
