Sandvik 22.11.L is a chromium-nickel strip electrode used for electro-slag welding (ESW) to deposit a single layer overlay of corrosion resistant alloy of 19%Cr/9%Ni composition on carbon- and low alloyed steels. It can also be combined with Sandvik 19.9.L for surfacing of two layer overlays.
- ISO 14343: 22 11 L
- AWS A5.9/ASME SFA5.9: EQ(309L)

Chemical composition (nominal) %
The ferrite content is nominally FN 13 according to WRC-92.
Sandvik 22.11.L is a multi purpose grade used for corrosion resistant weld surfacing of components in the chemical, petrochemical, nuclear and 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 or 22.8.3.L, for better corrosion resistance.
Weld metal characteristics
Typical chemical composition of single layer obtained on C-Mn steel and low-alloyed steel.
|Welding process and consumable||Type of overlay||C||Cr||Ni||FN, WRC|
|ESW22.11.L/47S||304, 304L, E308, E308L||≤0.06||17.5-19.5||9-10.5||3-8|
Consider the figures as examples. Parameters selected and conditions influence the result. Please contact Sandvik for details and guidelines.
Mechanical properties of overlay
Passes side bend testing according to ASME Section IX.
- The resistance to general corrosion is good in many mildly corrosive media
- The resistance to intergranular corrosion in Strauss testing (ASTM A262 Practice E) is good if the overlay is not post-weld heat-treated - unless the carbon content is maximum 0,03 %
- In pitting corrosion applications Mo-alloyed strip electrodes shall be selected
