Sandvik 22.8.3.L (Welding strip)
Datasheet updated 2011-12-05 14:53:54 (supersedes all previous editions)
Sandvik 22.8.3.L is a strip electrodes used to obtain a 2209 (SAF 2205) of corrosion resistant overlay weld deposit on C-, CMn- and low-alloy steels using submerged-arc welding (SAW) with the flux Sandvik 10SW or electroslag welding (ESW) with the flux Sandvik 47S. There are also other possible combinations and conditions.

Mechanical properties of overlay
Passes side bend testing according to ASME Section IX.
Corrosion properties of overlay
Equal to the base metal UNS S31803 and to UNS S32205, provided a welding procedure resulting in a PRE value exceeding 34 is selected.
Good resistance to stress corrosion cracking.
The resistance to intergranular corrosion is good.
In constructions that have to be post-weld-heat-treated Sandvik 22.11.L or 24.13.L should be used for the first layer and the heat treatment be carried out before welding the subsequent layer(s).

Direct current, with electrode positive is normally used.
The welding data in the table represent the operation capability of the flux. The desired properties of the overlay are obtained by proper selection of the settings within the ranges.
Applications
Sandvik 22.8.3.L is used for weld surfacing of components in the chemical, petrochemical, marine idustries where corrosion resistance on level with the duplex stainless steel UNS S31803 or UNS S32205 (Sandvik SAF 2205) is required. Typical components are pressure vesels, heat exchangers, shafts, idustrial piping etc.
