Nitronic® 50 is an austenitic stainless steel combining corrosion resistance and strength not found in any other commercial material available. It has approximately twice the yield strength at room temperature Types 316 and 316L and better corrosion resistance than 317L. The alloy maintains strength at both elevated and sub-zero temperatures. And, unlike many austenitic stainless steels, the alloy does not become magnetic when cold worked.

Nitronic®50 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.
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.
Cut to lengths
Nitronic®50 is non hardenable by heat treatment.
