Application
This electrode is ideal for welding titanium or niobium-stabilized austenitic stainless steels containing molybdenum. It can also be used as an alternative for welding unstabilized grades such as 316/316L. However, it is not recommended for structural applications exceeding 400 °C nor for cryogenic uses. Furthermore, it is employed for depositing corrosion-resistant overlays and for forming valve seat inserts on medium carbon steels. This electrode is generally supplied with a typical ferrite content ranging from 3 to 14 FN. No preheat operation is required and the maximum interpass temperature is set at 250 °C.
Alloy Type
Nb stabilized, Mo-bearing stainless steel.
Microstructure
Austenite with 3-14FN (3-12% ferrite), typically 10FN.
