Exera® 316LVM is a vacuum remelted, molybdenum alloyed, austenitic stainless steel.
The grade is characterized by:
C | Si | Mn | P | S | Cr | Ni | Mo | Cu | N |
---|---|---|---|---|---|---|---|---|---|
≤0.025 | 0.6 | 1.7 | ≤0.025 | ≤0.003 | 17.5 | 14 | 2.8 | ≤0.10 | ≤0.10 |
Exera® 316LVM is used for implant applications; hip stems, femoral heads, spinal systems, acetabular cups, intramedullary nails, bone screws, knee joints, and pins, bone and nail plates, internal fixation devices, dental implants, staples.
This grade is also used for cardiovascular applications: guide wires, cardiac stents and for surgical instruments and tools; blood lancets, stylets, trocars.
Exera® 316LVM has very good resistance in physiological environments to:
Exera® 316LVM is capable of passing the Moneypenny Strauss intergranular corrosion test, in accordance with ISO / ASTM requirements.
Size range:
Spools: 0.010-2 mm (0.0004-0.79 in.)
Coils: 1-5 mm (0.039-0.197 in.)
The wire in spools/coils is delivered bright drawn.
Ground bars: h8 as standard, h6 on request
Drawn in coil/spool: D2
Tighter tolerances can be offered on request.
Bright drawn: diameter 0.60-5.0 mm (0.02-0.197 in.)
Ground diameter: 0.6-10 mm (0.02-0.394 in.)
Drawn, straightened: h9
Tighter tolerances to be discussed in each and every individual case
Exera® 316LVM can also be supplied as bar (round) and tube (thick wall or thin wall), then under the trademark Alleima® 316LVM.
