COBALT-CONTAINING ALLOY

MP35N Cobalt-Containing Alloy

MP35N is a high-strength alloy containing cobalt, nickel, chromium and molybdenum. Its condition-dependent properties make it relevant where corrosion resistance and fatigue performance are needed together. Annealed and strengthened material should not be described against the same mechanical expectation.

One alloy, different mechanical conditions

Chemical analysis alone does not establish strength; cold work and ageing are also decisive. Starting material that must be formed can require a different condition from the high-strength final component. Define operation sequence, deformation and final testing together rather than treating the highest catalogue value as a guarantee for every delivery.

Corrosion and intended use

Marine and precision mechanical applications require fluid, temperature and stress conditions to complete the selection. Nonmagnetic behaviour may also matter to the design. Examples of use in medical devices do not establish implant suitability for every MP35N product; medical applications require their own material specification, traceability and acceptance requirements.

Final-treatment distinctions for bar

AMS 5844 illustrates work-strengthened bar, while AMS 5845 includes subsequent ageing. Confirm that the required diameter and tests fall within the applicable specification. State UNS R30035, product form, dimensions and condition together. MP159 may address related applications, but it is a different alloy rather than an automatic mechanical equivalent.

Typical application areas

High-strength fastener and spring components, marine parts and precision mechanical hardware.
