Electrodes for Creep Resisting Steels

MOLYTHERME (SPL) Mod

AWS: SFA

EN ISO CODE:

Extra low hydrogen type electrodes depositing a high strength weld metal. The electrode possesses excellent operating characteristics and is suitable for welding in all positions. Weld metal has got good toughness even at subzero temperatures. Deposition efficiency is about 115% min. The weld metal possesses high strength together with good notch toughness even at subzero temperatures down to minus 50oC. Ideally suited for welding components made of steel to IS:2062 Gr. E410, E450, IS:2002-Gr3, IS:1875-04 class 3A or similar.
