Sandvik 19.9.L (Welding strip)
Datasheet updated 2011-10-13 13:24:16 (supersedes all previous editions)
Sandvik 19.9.L is a strip electrode used for the second layer to obtain a corrosion resistant overlay weld deposit on a transition layer of Sandvik 24.13.L, 23.12.L or 22.11.L on C-, CMn- and low-alloy steels using submerged-arc welding (SAW) with flux Sandvik 10SW or 10S or electroslag welding (ESW) with Sandvik 47S or 49S high-speed fluxes. Sandvik 19.9.L gives a 304L/E308L 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
On par with the base metal 304L. The weld deposit is resistant to intergarnular corrosion in Strauss testing (ASTM A262 Practice E)also after the commonly applied post-weld heat treatment specified for C-, CMn- and low-alloyed steels.
In pitting corrosion applications Mo-alloyed strip electrodes shall be selected. Contact Sandvik for more information.

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 19.9.L is used for weld surfacing of components in the chemical, petrochemical, nuclear, marine industries where corrosion resistance on par with 304L is needed. Typical components are pressure vessels, heat exchangers, shafts, indiustrial piping etc.
