NITRONIC® 32 Alloy Descriptionbutton

NITRONIC® 32 is a low nickel austenitic stainless steel that has almost twice the yield strength of 304 with comparable corrosion resistance. The alloy has high work hardening rate allows for high strength levels while maintaining good ductility.

Applications

Screens for the coal industry
Well screens
Screens for the food processing industry
Clamps for pole line hardware,
High strength non-magnetic springs
Wire forms
Racks and  cages

Nitronic® 32 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.

Additional Properties

Corrosion Resistance
Refer to NACE (National Association of Corrosion Engineers) for recommendations.

Standard Wire Finishes
Extra Clean:  Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”
Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications
Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation. A soap finish is available in tempered products.
Plated: Many plating options are available.
∗Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests.

Forms
Continuous Coils
Cut to lengths
Precision cutting

Heat Treatment
NITRONIC 32® is non hardenable by heat treatment.
