Sandvik 22.11.L is a strip electrode used to obtain a corrosion resistant overlay weld deposit on C-, CMn- and low-alloy steels using electroslag welding (ESW) with the flux Sandvik 47S. It gives 304/304L/E308/E308L chemical composition when used in single layer technique or 304L/E308L when combined with Sandvik 19.9.L strip electrode for the second layer.

It can also be combined with Sandvik 19.9.LNb for the second layer to obtain 347/E347 or Sandvik 19.12.3.L to obtain 316L/E316L.

There are also other possible combinations and conditions.

Applications
22.11.L is a multi purpose grade used for corrosion resistant weld surfacing of components in the chemical, petrochemical, nuclear, marine industries. Typical components are pressure vessels, heat exchangers, shafts, industrial piping etc

It is often used as transition layer on which a second layer is welded, using for example Sandvik 19.9.L, 19.9.LNb, 19.12.3.L, 22.8.3.L, for better corrosion resistance.
