What Is ASTM F138 Stainless Steel?
ASTM F138 is a specification for implant-grade stainless steel, commonly known as 316LVM (vacuum melted 316L).
It is specifically designed for medical and surgical applications requiring high purity and consistency.
ASTM F138 vs Standard 316L Stainless Steel
While both are similar chemically, ASTM F138 includes stricter controls:
- Vacuum melting (VAR or equivalent)
- Lower inclusion content
- Improved microstructure
- Better consistency for critical applications
This makes ASTM F138 suitable for implant use, unlike standard 316L.
Why ASTM F138 Matters
ASTM F138 is used where failure is not an option:
- Medical implants
- Surgical components
- Orthopedic hardware
The higher purity improves:
- Biocompatibility
- Corrosion resistance
- Reliability in the human body
