Weld Star – Alloy 625 (NiCrMo-3) TIG is a high nickel alloy wire specifically developed for welding and cladding nickel-based alloys such as 625. Utilising solid drawn technology, it ensures cleaner and high-quality welds, bright seams, and excellent ductility.
The weld metal exhibits impressive mechanical properties at both high and low temperatures. It is resistant to pitting and stress corrosion, making it suitable for extreme environments. The alloy has a working temperature range from cryogenic to 540°C, making it versatile for various applications.
Features and Benefits
- High Nickel Content: Developed specifically for welding and cladding nickel-based alloys like 625.
- Solid Drawn Technology: Ensures cleaner welds, bright seams, and enhanced ductility.
- Temperature Versatility: Suitable for a working temperature range from cryogenic to 540 degC.
- Corrosion Resistance: Offers resistance to pitting and stress corrosion.
- Diverse Applications: Ideal for use in the chemical process industry, marine engineering, nuclear reactor components, aerospace, and pollution control equipment.
Common Applications
- Chemical Process Industry: For equipment and components that handle corrosive chemicals.
- Marine Engineering: Provides resistance against the corrosive effects of seawater and other marine factors.
- Nuclear Reactor Components: Ensures the longevity and durability of components exposed to high-stress environments.
- Aerospace: For components that require high strength and corrosion resistance.
- Pollution Control Equipment: Suitable for equipment exposed to corrosive pollutants.
