DESCRIPTION AND APPLICATION
SELECTARC INOX 308B is a low-carbon stainless steel electrode with a basic-type coating.
It provides excellent weldability in all positions and is particularly effective when joint preparation is incomplete or inaccurate.
The deposited metal has very good mechanical properties and high impact resistance.
The electrode is intended for welding 18/8 type stainless steels at service temperatures from –196 °C to +350 °C.
