This steel is the classical austenitic stainless steel for medical applications. It has been specifically developed and originally optimized for internal fixation devices. It’s the American equivalent for the VAR remelted, ASTM F 138, 316LVM steel. The 1.4441 IMPLANT steel is ESR remelted to a particularly low S-content. Its composition ensures that it is Delta Ferrite free, and not forming ferromagnetic Alpha-martensite up to the highest required cold worked strengths. It can be easily cold worked to high strength levels. This steel has a good corrosion resistance, especially against pitting corrosion. And exhibits fair high fatigue endurance limit at 107 cycles.
This 1.4441/316LVM – IMPLANT steel is well adapted for numerous applications in the medical field and more particularly for bone surgery, like implants for joint replacement, internal fixation devices, high strength guide wires for internal and external fixations. It is also well indicated for non-medical applications with similar requirements, such as components of the watch exterior. It can be fairly easily machined.
We stock a comprehensive range of round bars, sizes between 0.60 mm and 25.40mm in diameter!
This is a fast-moving item, so we might not have all dimensions ex stock, but it is our intention to have at all times, all the sizes ex stock in Singapore.
