MP35N Alloy® – UNS R30035
Cobalt-Chromium according to ASTM F562 - ISO 5832-6
Description
The cobalt-based alloy MP35N has excellent corrosion resistance and very high mechanical properties with a maximum strength of over 2000 MPa while remaining ductile. The grade has excellent corrosion resistance, is biocompatible and has very good high temperature properties.
Stainless has qualified European and American sources in stock and a range of diameters to suit your processing requirements. This product can also be made to measure or cut into slugs by our service centres.
Each material is delivered with its producer’s certificate of origin in order to guarantee you total transparency and complete traceability.
Main applications
Due to its recognised biocompatibility in the medical field, the grade is used in the manufacture of implants (prostheses, stents, etc.) obtained by machining. Other fields of application include aeronautics, chemistry, oil, etc.
The material is available annealed, cold worked for small diameters or aged.

Machinability
Forgeability/Usability
The grade can be hot forged in the 1100/1200°C temperature range. Machining of this grade requires suitable equipment and tools. TIG welding is also possible on this grade.
Polishability
The high level of inclusionary cleanliness and the homogeneity of the microstructure of this grade allows optimum polishing.
Heat treatments
Annealing can be carried out in the 1040-1090°C temperature range to soften the grade. However, this treatment must be kept under control so as not to degrade the quality of the microstructure and the grain size. Aging on previously work-hardened states is done at 540-590°C for 4 hours.
Corrosion resistance
The grade is highly resistant to general corrosion and also to pitting due to its high chromium and molybdenum content combined with its low inclusion rate. The grade also has very low susceptibility to hydrogen embrittlement and stress corrosion.
