Alloy 302 is an austenitic stainless steel which has better corrosion resistance than alloy 301. With it’s higher nickel content alloy 302 does not work harden as quickly as alloy 301. The alloy is not hardenable by heat treatment and in non-magnetic in the annealed condition. It becomes increasingly magnetic with cold working. If carbide precipitation is an issue 304 may be a better choice with its lower carbon content.

∗Alloy 302 can be supplied in a rolled tempered condition. Contact Ulbrich Wire Technical Service for details.
Refer to NACE (National Association of Corrosion Engineers) for recommendations
Standard Wire Finishes
Extra Clean: (XC) 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.
