GENERAL PROPERTIES

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 sulphuric, hydrochloric, acetic, formic and tartaric acids, acid sulphates and alkaline chlorides.

 

RESISTANCE TO CORROSION

The molybdenum bearing alloys such as Types 316 and 316Ti stainless steels are more resistant to atmospheric and other mild types of corrosion than the 18Cr-8Ni stainless steels. In general, media that do not corrode 18-8 stainless steels will not attack the molybdenum-containing grades. One known exception is highly oxidizing acids such as nitric acid to which the molybdenum bearing stainless steels are less resistant. Types 316 and 316Ti are considerably more resistant than any of the other chromium-nickel stainless steels to solutions of sulphuric acid. Where condensation of sulphur-bearing gases occurs, these alloys are much more resistant than other types of stainless steels. In sulphuric acid solutions, the acid concentration has a strong influence on the rate of attack.

WELDING

The alloy can be easy welded without hot cracking phenomenon, using an adequate filler metal (from 5 to 15% ferrite). The alloy is not sensitive to cold cracking phenomenon. All welding processes can be used including filler processes.

HEAT TREATMENT

Alloy 316Ti is non hardenable by heat treatment.
