316Ti / UNS S31635 / 1.4571
is a Titanium stabilized austenitic stainless steel. 2% Molybdenum bearing ensures better corrosion resistance than 304 grade, particulary regarding to uniform and localized corrosion. The grade is stabilized by the addition of Titatnium that avoids intergranular corrosion and ensures good mechanical properties at room and elevated temperature. It ia an austenitic microstructure grade, free of deleterious carbide precipitations but containing CNTi precipitations on grain boundaries. The grain is regulary fine and contains some residual ferrite (approx. 4%) after solution annealing (1050-1150^C - 192-2102°F) and water quenching. This steel resists much better to wet atmosphere or solution containing chloride or flouride addition. It is not seawater resistant. The alloy may be used in diluted chloridric or sulphuric acids at low temeperature (0=330°C - 626°F) as well as in sour organic solutions. The grade ia also well known for its high ductility, particularly when considering cold forming.
Typical applications:
- chemical industry
- mechanical engineering
- construction and pipeline engineering
- medical and phramaceutical industry
- ship building
