2.4967 – 2.4964 – Alloy 25 is a cobalt-nickel-chromium superalloy designed for use in corrosive environments and commonly used in medical applications like implants. It possesses high tensile strength and good corrosion resistance and if the hardness is <35HRC it is suitable for petrochemical applications use in H2S- / Sulfur containing environments in oil and gas production per NACE MR0103 / NACE MR01075.
Alloy 25 is a superalloy available in annealed and hardened condition, where the hardening treatment (cold working) elevates the Rp0,2 to >760 Mpa and the UTS to >1250 Mpa but trades off on elasticity. It is commonly used in marine / petrochemical environments due to its’ superior corrosion resistance and maintains it’s properties very well under elevated temperatures up to 1100*C. Due to it’s biocompatibility, it also sees a primary use in the medical field for example for hip implants or for surgical fixation wires.
