Alleima® 316LVM is a vacuum remelted, molybdenum alloyed, austenitic stainless steel and is used for implant and other medical applications. It is also suitable for the watch industry because of its absolute cleanliness and excellent polishing properties.

The grade is characterized by:

  • High strength
  • High fatigue strength
  • Excellent micro-cleanliness
  • Excellent structural homogeneity
  • High surface finish

Standards

  • UNS: S31673
  • EN Number: 1.4441

Testing and certification can be performed according to ASTM F139 and ISO 5832-1.

Corrosion resistance

Alleima® 316LVM has very good resistance in physiological environments to:

  • General and intergranular corrosion due to high purity and low ferrite content
  • Pitting and crevice corrosion due to the high molybdenum content

Alleima® 316LVM is capable of passing the Moneypenny Strauss intergranular corrosion test, in accordance with ISO/ASTM requirements.
