Why choose ABRAFIL 276?
1. Outstanding corrosion resistance
-
Excellent resistance to almost all corrosive agents: strong acids (hydrochloric, sulfuric, phosphoric, acetic), oxidizing and reducing media.
-
Very good chloride resistance, even at high temperatures → resists stress corrosion cracking (SCC) and crevice/pitting corrosion.
2. High chemical versatility
-
ABRAFIL 276 is highly stable even in the face of acid mixtures, variable redox conditions, or highly acidic + chlorinated media – making it virtually unrivalled in extreme chemical environments.
-
Ideal for chemical and pharmaceutical plants, gas treatment plants, etc.
3. Excellent weldability
-
Good fluidity, stable arc in MIG, very little spatter, good bath wetting.
-
Suitable for welding C276 parts, but also other Ni-Cr-Mo alloys and even dissimilar assemblies (e.g. Inconel ↔ carbon steel or stainless steel).
4. Correct thermal resistance
-
Withstands temperatures up to approx. 1040°C, depending on operating conditions.
-
Can be used in both hot and corrosive environments.
