316Ti Stainless Steel Wire UNS S31635

Shaped, Flat, Square, Round, Fine Wire, Plated and Un-plated ASTM A240

316Ti Alloy Description

Type 316Ti is a titanium stabilized variation of alloy 316. This austenitic chromium-nickel stainless steel containing molybdenum which increases the corrosion resistance, improves resistance to pitting chloride ion solutions and provide increased strength at elevated temperatures. Properties are similar to those of alloy 316 except that 316Ti due to its Titanium addition can be used at elevated sensitization temperatures. Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids, acid sulfates and alkaline chlorides.

Alloy 316Ti 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 more information.

Cold Forming

Alloy 316Ti can be readily formed and drawn.

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
Heat Treatment
Alloy 316Ti is non hardenable by heat treatment.
Welding
For best results refer to: SSINA’s “Welding of Stainless Steels and Other Joining Methods”.
