S31673 Special Stainless Steel for Surgical Implants
316LVM is a variety of grade 316 stainless steel produced by A-ONE ALLOY. 316LVM goes through a process of electric arc melting, followed by vacuum arc remelting that results in a highly uniform chemistry that contains a minimal amount of impurities. Due to its lack of contaminants and high resistance to corrosion, 316LVM is commonly used in temporary and permanent medical implants (sutures, surgical staples and bone pins) and body piercing jewelry.
