Nickel, Cobalt, and Titanium Alloys
Cobalt Alloys
MP35N™
Overview & Features
It has high resistance to stress corrosion cracking caused by sulfides and shows excellent performance in natural gas drilling in high hydrogen sulfide atmospheres. In seawater, it has the highest resistance to crevice corrosion, stress corrosion and pitting.
Additionally, this is often used in medical applications such as implants and dental instruments because of its high biocompatibility. It is also used in temperatures ranging from cryogenic to 454°C.
TOKKIN supplies a wide variety of shapes, including foils and sheets, as well as ultrafine pipes, rods, and plates.

Mechanical Properties
The table below shows correlations of rolling ratio and tensile strength.
Its strength can be improved by age-hardening treatment(heat treatment).
Heat Treatment
■ Annealing Condition
［Heating at 1040～1100℃ → cooling］
■ Ageing Treatment
Ageing Treatment is performed
To obtain optimum mechanical properties, aging treatment is performed [holding at 550-600℃ for 4 hours → air cooling] after cold working.
