介绍 | Sandvik 21.13.3.L is a strip electrode used to obtain 316L of corrosion resistant overlay weld deposit in single layer on C-, CMn- and low-alloyed steels using electroslag welding (ESW) with the flux Sandvik 47S. Combined with 19.12.3.L for the second layer it will give 316L weld deposit. It can also be used in submerged-arc welding with the flux 10SW in combination with Sandvik 19.12.3.L for the second layer to obtain a 316L weld deposit. Combined with Sandvik 19.13.4.L for the second layer it will give 317L weld deposit. Combined with Sandvik 20.25.5.LCu for the second layer it will give E385 weld deposit. There are also other possible combinations and conditions. Applications Sandvik 21.13.3.L is used for corrosion resistant weld surfacing, in particular where pitting corrosion is involved, of components in the chemical, petrochemical, marine industries. Typical components are pressure vessels, heat exchangers, shafts, industrial piping etc. It is used in applications where corrosion resistance similar to 316/316L is required. |
