介绍 | Sandvik 19.9.LNb 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.LNb, 24.13.L, 21.11.LNb or 22.11.L on C-, CMn- and low-alloy steels using submerged-arc welding (SAW) with the fluxes Sandvik 10SW or 10S or electroslag welding (ESW) with the fluxes Sandvik 47S or 49S the high speed flux. It gives a 347/E347 weld deposit. There are also other possible combinations and conditions. Applications Sandvik 19.9.LNb is used for weld surfacing of components in the chemical, petrochemical, nuclear industries where corrosion resistance on level with 347 is needed. Typical components are pressure vessels, heat exchangers, shafts, industrial piping etc. It is very common in the petrochemical industry. |
