Why choose ABRAFIL 625?
1. Excellent high-temperature resistance
ABRAFIL 625 retains its mechanical properties at temperatures of up to 980°C, making it the preferred choice for the thermal, petrochemical and turbine industries.
2. Very high corrosion resistance
Thanks to its nickel-, chromium- and molybdenum-rich composition, it effectively resists pitting, crevice and stress corrosion. It is particularly suited to marine, chemical, chlorinated or highly oxidizing environments.
3. Versatility for welding dissimilar materials
ABRAFIL 625 is often used to join dissimilar materials, such as stainless steels with carbon steels or other nickel-based alloys. It is also used as a transition filler metal in heterogeneous assemblies.
4. Excellent mechanical properties
ABRAFIL 625 offers excellent tensile strength, fatigue strength and hot crack resistance. It is recommended for structures under pressure or subject to high mechanical stress.
