Stainless steel
Rex 734
1.4472
This High-Nitrogen stainless steel offers better tensile strength, wear resistance, resistance to pitting and crevice corrosion than the 316LVM grade. Obtained through slag remelting, this grade contains no ferrite and the inclusion cleanliness of its microstructure makes it non-magnetic and biocompatible with human tissue. This alloy is used in the manufacture of heavy-use orthopaedic implants and osteosynthesis devices, such as very thin screws or high-mobility prosthesis.
Key benefits
Yield strength (up to) twice higher than 316LVM in annealed condition
High corrosion resistance
Good forgeability
