ASTM F138 Stainless Steel Supplier (316LVM Round Bar)
Looking for ASTM F138 stainless steel round bar?
At Mozaic Precision Metals, we supply 316LVM stainless steel that meets ASTM F138 requirements for medical and implant-grade applications.
What Is ASTM F138?
ASTM F138 is a specification covering wrought 18Cr-14Ni-2.5Mo stainless steel bar and wire for surgical implants.
It is commonly known as:
- 316LVM stainless steel
- Vacuum arc remelted (VAR) stainless
- Implant-grade stainless steel
What Makes ASTM F138 Different?
Compared to standard 316L:
- Vacuum melted (cleaner microstructure)
- Lower inclusion content
- Improved consistency
- Designed for biocompatibility
👉 This is critical for medical and surgical applications
