DESCRIPTION OF F139 SHEET
The 316LVM material has been used for permanent implants for many years. Good corrosion resistance under annealing conditions. The 316LVM has been used as a reference for many studies on new alloys. This stainless steel has good ductility under cold working conditions. Applications include: sutures, orthopedic cables, skin-closing staples, catheters, probes, bone screws, and many minicomputer parts

This specification covers the chemical, mechanical, and metallurgical requirements of forged 18Cr-14Ni-2.5Mo stainless steel sheets and strips used to make surgical implants.
Values expressed in SI units or inch-pound units shall be considered standard values, respectively. The values specified in each system may not be exactly the same; therefore, each system should be used independently. Combining the values of the two systems may cause non-compliance.
