SAF Safdual 400 description: SAFDUAL 400 is a basic flux cored wire with excellent mechanical properties, suitable for the welding of heavy sections. Excellent low temperature impact toughness in both the as welded and stress-relieved conditions. Stable arc, spatter-free both in the flat and vertical positions. The weld deposit has a very low hydrogen content and a good crack resistant. Preferably used under mixed gas, however the use of CO2 for short and spray arc processes is possible.
