317 Alloy Description


Alloy 317 is an austenitic chromium-nickel stainless steel that possesses excellent corrosion resistance. Of all the 300 series stainless steels, alloy 317 is the most corrosion resistant and has the highest tensile and creep strength properties at elevated temperatures. The high molybdenum content the alloy’s superior pitting resistance.

Alloy 317 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

See 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.

Forms

Continuous Coils
Cut to lengths
Precision cutting

Cold Forming

Alloy 317 can be readily formed and drawn.

Heat Treatment

Alloy 317 is non hardenable by heat treatment.
