316Ti (UNS S31635) is a titanium stabilised version of 316
molybdenum-bearing austenitic stainless steel. The 316 alloys are more resistant to
general corrosion and pitting/crevice corrosion than the conventional
chromium-nickel austenitic stainless steels such as 304. They also offer higher
creep, stress-rupture and tensile strength at elevated temperature. High carbon
Alloy 316 stainless steel can be susceptible to sensitisation, the formation of
grain boundary chromium carbides at temperatures between approximately 900 and
1500°F (425 to 815°C) which can result in intergranular corrosion. Resistance to
sensitisation is achieved in Alloy 316Ti with titanium additions to stabilise the
structure against chromium carbide precipitation, which is the source of
sensitisation. This stabilisation is achieved by an intermediate temperature heat
treatment, during which the titanium reacts with carbon to form titanium carbides.
This significantly reduces susceptibility to sensitisation in service by limiting
the formation of chromium carbides. Thus, the alloy can be used for extended periods
at elevated temperatures without compromising its corrosion resistance. 316Ti has
equvilent corrosion resistance to sensitisation as the low carbon version 316L.
