MIM Stainless Steel

 

GRADE	TYPE	DESCRIPTION	APPLICATIONS
MIM 430L	Ferritic	Magnetic stainless steel with resistance to atmospheric corrosion and general oxidation.  Lower cost than nickel-containing austenitic stainless steels.	Sensors, armatures, and pole pieces that require some resistance to corrosion
MIM 316L	Austenitic	Non-magnetic stainless steel with excellent corrosion resistance, toughness, and ductility	Medical and dental devices, marine components, and non-magnetic housings
MIM Duplex	Duplex (Ferritic/Austenitic)	Weakly magnetic stainless steel providing a mix of properties between the austenitic and ferritic grades	Lock components
17-4PH	Precipitation Hardening	Provides an excellent combination of strength, hardness, and corrosion resistance	Ordnance components, high strength fasteners, fiber optic connectors, and medical devices
MIM 440C	Martensitic	Provides high strength, hardness, and resistance to wear with moderate resistance to corrosion	Wear plates, fuel injection nozzles, and cutting instruments.

MIM Low Alloy Steel

GRADE	TYPE	DESCRIPTION	APPLICATIONS
MIM 2200	Low Carbon Nickel-Steel	Provides outstanding toughness and ductility; carburized surface provides an excellent wear surface with a tough core	Lubricated safety and security devices, automotive interior components, and coated or plated hardware

Soft Magnetic Alloys

GRADE	TYPE	DESCRIPTION	APPLICATIONS
MIM Fe	Iron	Provides high magnetic induction for DC applications where low coercive force and high permeability are not required	Pole pieces, sensor probes, and solenoid end caps
MIM 3Si	Silicon-Iron	Provides higher permeability and lower coercive force compared to iron	Solenoid switches, armatures, pole pieces, and relays
MIM 50Ni	Nickel-Iron	Provides higher permeability and reduced coercive force compared to 3Si, at the expense of magnetic induction	Pole pieces, cores, and relays
MIM 430L	Ferritic	Combines good magnetic output with corrosion resistance	Magnetic probes, sensors, armatures, and pole pieces

Low Expansion Alloys

GRADE	TYPE	DESCRIPTION	APPLICATIONS
MIM F15	Fe-28Ni-18Co	F15 (trade name Kovar) provides a low and consistent coefficient of linear expansion up to 750 °F (400 °C)	Commonly used when glass-to-metal seals are required
MIM Alloy 36	Fe-36Ni	Alloy 36 (trade name Invar) provides a very low coefficient of linear expansion up to 300 °F (150 °C)	Commonly used when glass-to-metal seals are required
MIM Alloy 42	Fe-42Ni	Alloy 42 provides a low and consistent coefficient of linear expansion up to 575 F (300 °C)	Commonly used when glass-to-metal seals are required
