Stainless austenitic chromium-nickel steel
The material 316 Ti is a stainless austenitic chromium-nickel steel which is characterised by its increased resistance to corrosion as well as pitting. Its corrosion properties are roughly comparable with those of material number 316. The stainless steel has good resistance to most acids – apart from hydrochloric acid and sulphuric acid –, even at high concentrations and temperatures.
Compared to titanium-unstabilised steels, 316 Ti has better resistance to intergranular corrosion. The addition of titanium prevents the precipitation of chromium carbides in the grain boundaries during long-term heating in the temperature range of about 450 – 850 °C.
