Key Features of Hastelloy Filler Wire

• Nickel-Based Alloy Construction – Manufactured from corrosion-resistant nickel alloy compositions suitable for demanding welding applications.
• Multiple Hastelloy Grades – Available in commonly used grades such as C276, C22, B2, B3 and other application-specific compositions.
• Grade-Matched Welding – Filler wire can be selected to closely match the Hastelloy base material for reliable weld performance.
• Excellent Corrosion Resistance – Provides strong resistance to a broad range of aggressive chemical environments.
• Resistance to Pitting – Suitable for applications where localized pitting corrosion can be a concern.
• Crevice Corrosion Resistance – Selected Hastelloy grades provide excellent resistance to corrosion in restricted or stagnant areas.
• Chloride Resistance – Suitable for welding components exposed to chloride-containing process environments.
• Stress Corrosion Cracking Resistance – Certain Hastelloy grades provide strong resistance to stress corrosion cracking under suitable service conditions.
• High Molybdenum Content – Hastelloy grades containing significant molybdenum offer enhanced resistance to localized corrosion.
• Chromium Alloying – Chromium contributes to oxidation and general corrosion resistance in appropriate environments.
