Sandvik 19.12.3.L (Welding strip)
Datasheet updated 2011-10-13 13:24:16 (supersedes all previous editions)
Sandvik 19.12.3.L is a strip electrodes used for the second layer to obtain a corrosion resistant overlay weld deposit on a transition layer of Sandvik 24.13.L , 22.11.L or 21.13.3.L on C-, CMn- and low-alloy steels using submerged-arc welding (SAW) with the flux Sandvik 10SW or electroslag welding (ESW) with the fluxes Sandvik 47S or 49S the high speed flux.
Sandvik 19.12.3.L gives a 316L/E316L weld deposit. 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 316L. The resistance to pitting corrosion better than for 304L. The resistance to acids, except nitric acid, is also better than for 304L.

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
19.12.3.L is used for weld surfacing of components in the chemical, petrochemical, marine industries where corrosion resistance on par with 316L is required. Typical components are pressure vessels, heat exchangers, shafts, industrial piping etc.
