A time-honored
medical material

 
316LVM

This stainless steel alloy is a unique nomenclature for Fort Wayne Metals and meets all the requirements of 316LS. Mainly used for permanent implants, 316 LVM’s corrosion resistance is controlled by a reduced carbon content compared to the other 300 series alloys. The material is vacuum re-melted, giving it a more uniform chemistry with minimal voids and contaminants.
