316Ti Stainless Steel Description

Type 316Ti(UNS 31635) is a Titanium stabilized austenitic chromium-nickel stainless steel containing molybdenum. This addition increases corrosion resistance, improves resistance to pitting chloride ion solutions and provide increased strength at elevated temperatures. Properties are similar to those of type 316 except that 316Ti due to its Titanium addition can be used at elevated sensitisation temperatures. Corrosion resistance is improved, particularly against sulfuric, hydrochloric, acetic, formic and tartaric acids, acid sulfates and alkaline chlorides.

Additional Properties

Corrosion Resistance
See NACE (National Association of Corrosion Engineers) for more information.

#1-Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.
#2D-Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.
#2B–Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D.
#BA-Bright annealed cold rolled and bright annealed
#CBA-Course bright annealed cold rolled matte finish and bright anneal
#2-Cold Rolled
#2BA-Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part.
Polished-Various grit finish for specific polish finished requirements
*Not all finishes are available for all alloys – Contact Ulbrich Sales for more information

Wire – Finishes
XC-Extra clean bright annealed or bright annealed and cold rolled
Grease-Ultra bright finish for decorative applications
Soap-Soap is not removed from tempered wire to act as a lubricant
*Contact Ulbrich Wire for custom wire finishes

Cold Forming
Type 316Ti can be readily formed and drawn.

Heat Treatment
316Ti is non hardenable by heat treatment.
