316LVM Bar UNS S31673 DIN X2CrNiMo18-15-3 ASTM F138 Stainless Steel
Round Bar
316LVM is a vacuum remelted, molybdenum alloyed, austenitic
stainless steel.
The grade is characterized by:
- High strength
- High fatigue strength
- Excellent microcleanliness
- Excellent structural homogeneity
- High surface finish
Standards
- UNS: S31673
- DIN: X 2 CrNiMo 18 15 3
Product standards
316LS / 316LVM surgical steels are electroslag remelted (ESR) or
vacuum arc remelted (VAR), low carbon, high nickel and molybdenum
versions of 316 stainless steel. A second high-quality melting step
improves cleanliness. Chemical modification is designed to maximize
the alloy's corrosion resistance and provide a ferrite-free
microstructure. The alloy is non-magnetic even after a rigorous
cold forming operation

316L VM stainless steel, commonly referred to as surgical grade or
implant grade stainless steel, is the most commonly used medical
stainless steel for sale. Decomposition name, this is a low-carbon
version of 316, which has been remelted by electroslag or vacuum
arc to reduce impurities.
Compared with ordinary stainless steel, this process can remove
impurities and help to form a more effective chromium oxide layer
on the surface of the material. This layer helps to keep the nickel
in the rod, preventing it from triggering an allergic reaction.
This protective surface also increases the time that the implant
can remain in the body without penetrating the surrounding tissue.
