What Is ASTM F138 Stainless Steel? (316LVM Explained)

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.

While both are similar chemically, ASTM F138 includes stricter controls:

This makes ASTM F138 suitable for implant use, unlike standard 316L.

ASTM F138 is used where failure is not an option:

The higher purity improves:
