Sandvik 11R51 and Sandvik 11R51 HV (vacuum remelted) are austenitic stainless steels alloyed with molybdenum that are characterized by high tensile strength and high resistance to corrosion, fatigue and relaxation.

Vacuum-remelted Sandvik 11R51 HV offers higher cleanliness compared to Sandvik 11R51, which is usually required for medical applications.

Compared with the standard grade Sandvik 12R10 medical wire, Sandvik 11R51 and Sandvik 11R51 HV offer:

  • Higher tensile strength and tempering effect
  • Higher relaxation resistance, especially at elevated temperatures
  • Higher fatigue strength
  • Better corrosion resistance, through the addition of molybdenum

Service temperature: -200 to 300°C (-330 to 570°F)
These grades are used for applications such as root canal files, reamers, broaches, surgical suture needles, braces, and acupuncture needles.
