MP35N Alloy Sheet

MP35N sheet is primarily used in applications requiring precision stamping and etching, where there are stringent demands for ultra-high strength, corrosion resistance, and non-magnetic properties; it combines exceptional mechanical strength with outstanding corrosion resistance. Capable of withstanding stress corrosion and harsh environments, the alloy is frequently selected for fasteners and springs.

MP35N alloy sheet exhibits excellent corrosion resistance in hydrogen sulfide, saltwater, and other chloride solutions. Thanks to these characteristics, it is commonly used to manufacture components for marine environments-such as cables for deep-sea measurement sensors-and finds extensive application in the automotive and aerospace industries.

The form factor of sheet material precludes the type of turning operations used for bar stock; the processing methods differ significantly:

Precision stamping: Suitable for small components such as surgical clips and orthodontic brackets. Typically, strip material is sourced in an annealed or lightly cold-rolled state; age hardening is performed after the stamping process.

Bending/Deep drawing: Springback control is essential. While the material exhibits good ductility in the annealed state, its work-hardening rate is extremely high, potentially necessitating intermediate annealing.

Laser cutting/Waterjet cutting: TE Connectivity has confirmed that MP35N sheet material is compatible with laser processing for precision contour cutting in medical device applications.

Key limitation: Sheet material in the aged condition (HRC 50–55) is virtually impossible to shape via conventional machining; only grinding, EDM, or laser processing are viable options. Consequently, the design of the overall process flow is more critical than the optimization of any single operation.
