The deposit is predominantly martensitic. It combines good toughness with excellent resistance to cavitation and to stress
corrosion cracking. Typical applications include repairing of casting defects, fabrication and rebuilding on components used in the water turbines and pump, rebuilding and repairing casting defects, fabrication and rebuilding work on propellers.
interpass temperature should be kept
below 150°C and the heat input be kept
below 1.5 kJ/mm to achieve maximum
weld metal impact toughness, especially
in as-welded condition. A post-weld heat treatment at 580°C - 620°C is advised to obtain a tempered martensite that combines ductility, corrosion
resistance and cavitation resistance.
16% Cr – 5% Ni – 1% Mo soft martensitic deposit.
Ferrite and martensite.
Materials to be welded
