Alloy 316LVM • UNS S31673

Alloy 316LVM is a high-performance stainless steel alloy that is specifically designed for medical and surgical applications. It is an austenitic stainless steel, which means it has a face-centered cubic crystal structure and excellent mechanical properties. The “L” in 316LVM stands for low carbon, indicating that the alloy has a lower carbon content compared to standard 316 stainless steel.

One of the key features of alloy 316LVM is its exceptional corrosion resistance. It exhibits excellent resistance to a range of corrosive environments, including harsh chemicals, acids, alkalis, and chloride solutions. This makes it highly suitable for use in medical implants, devices, and bone screws that encounter bodily fluids or harsh sterilization processes.

Alloy 316LVM also offers excellent mechanical properties, including high tensile strength, good ductility, and high elongation. It has a low magnetic permeability, which is beneficial for certain medical applications where magnetic interference needs to be minimized.
