The new Mo free duplex stainless steel UR2202 was
developed by Industeel in close cooperation with Ugitech -
Schmolz + Bickenbach. It can be used in many construction
or transport applications, as a substitute for 304 and 304L.
With at least the same corrosion properties, the new UR2202
has higher mechanical properties. This provides the potential
for significant weight savings for fabricated tanks, pressure
vessels etc., when compared to the austenitic grade.
Different welding products are considered to achieve
homogeneous or heterogeneous welds with the lean duplex
base metal and can be selected according to the required
corrosion resistance, toughness and tensile properties.
