Titanium's strong affinity to carbon reduces the precipitation of chromium carbides and hence a susceptibility to intergranular attack. Thus, the carbon content does not need to be reduced to avoid this type of corrosion and the addition of Titanium maintains better mechanical properties. Furthermore, titanium stabilised austenitic stainless steels are weldable without heat treatment and are used in construction or for high temperature service (e.g. DMV 321). When used in conjunction with aluminium, titanium can produce precipitates which improve hot strength (e.g.DMV 800).
