316LVM Stainless Steel Bar

316 LVM stainless steel bar — engineered for exceptional material purity and consistency, purpose-built for surgical implant and precision medical device manufacturing.

What CNC shops actually notice when switching from commercial 316L bar to 316LVM is machining consistency — fewer hard inclusion particles mean fewer unexpected tool-edge chips during turning and a more uniform surface finish straight off the lathe, before any secondary polishing. For manufacturers running lights-out CNC cells producing thousands of small orthopedic screws or pins, that consistency reduces scrap rate in a way that's hard to achieve with standard melt-practice 316L.

Bar stock is supplied straightened and centerless ground where required, with diameter tolerances tightened to suit downstream Swiss turning or multi-spindle machining. Typical end uses include:

1. Bone screws and fixation pins
2. Spinal fusion rods and connectors
3. Surgical instrument shafts subject to repeated autoclave cycles
4. Dental abutment blanks

Like the sheet product, 316LVM bar retains the corrosion resistance and non-magnetic properties expected of medical-grade stainless steel, while offering tighter control over grain structure and surface defects than commercial 316L bar. Bars are supplied in round or hexagonal profiles, with straightness and diameter tolerances suited to downstream CNC machining.
