316LVM is a special type of 316L used in the medical industry primarily because unlike most other stainless grades it is implantable. The grade is a low carbon, vacuum remelted stainless steel that has high levels of purity and cleanliness as well as resistance to corrosion. ASTM F138 is the common medical specification for 316LVM.
Due to the material’s high strength, levels of purity, and strong corrosion resistance, 316LVM is used in a wide range of medical applications including the following:
- Fracture fixation devices
- Bone plates
- Trauma nails
- Bone screws
- Surgical instruments
- Surgical implant devices
316LVM is an austenitic grade of stainless steel. It has a high surface finish with excellent microcleanliness. 316LVM also possesses high fatigue strength and excellent structural homogeneity.
The purity and cleanliness that 316LVM offers is a result of the vacuum melt process that the material goes through. The vacuum melt process is typically the second melt, and the most common melts for this process are Electro Slag Re-melt (ESR), Vacuum Arc Re-melt (VAR), and Vacuum Induction Melt (VIM).
Although standard 316LVM may meet the limitations for some implants, typically the ASTM F138 specification is required for most implants. This specification refines the chemistry to improve the micro-cleanliness of standard 316LVM.
