Bio-medical grade stainless steel 316LVM:

         The reason why designated as 316LVM is that the Iron based-18Chromium-14Nickel-3Molybdenum alloy is 316L,a low-carbon variety of 316,which has been vacuum melted to improve purity and cleanliness,meanwhile resulting in a more consistent medical grade austenitic stainless steel.

         Because of its excellent corrosion resistance,316LVM is widely used for surgical implants(both temporary and permanent)and instruments,medical devices and equipment.

         Material designation: Fe-18Cr-14Ni-3Mo;

         Trade name: 316LVM;

         Standard specification:

               ◇ ISO 5832-1:1997 composition”D”: wrought 18Cr-14Ni-3Mo for surgical implants

               ◇ GB 4234-2003 composition"S31723": 18Cr-14Ni-3Mo for surgical implants

               ◇ ASTM F138: wrought 18Cr-14Ni-2.5Mo bar and wire for surgical implants

               ◇ ASTM F139: wrought 18Cr-14Ni-2.5Mo sheet and Strip for surgical implants

               ◇ ASTM F899: wrought stainless steel for surgical instruments

         Main advantages:

               ○ Low C → better corrosion resistance;
               ○ Vacuum Melt → better general and integranular corrosion resistance;
               ○ High Cr → better corrosion resistance;
               ○ High Ni → higher strength;
               ○ High Mo → better general and integranular corrosion resistance;


               △ Annealed → better ductility;
               △ Cold Worked → better corrosion resistance;
