Features
Alloy 82 is used for the welding of alloys 600, 601, 690, 800 and 800HT etc.
Weld metal deposited has high strength and good corrosion resistance, including oxidation resistance and creep rupture strength at elevated temperatures.
Ideal for dissimilar welding applications between various nickel alloys, stainless steels, carbon steels including overlay.
Suitable for applications ranging from cryogenic to high temperatures making this alloy one of the most used in the nickel family.
Precision layer wound for superior wire feeding characteristics.
Applications
1. ERNiCr-3 used for welding nickel-based alloys, high temperature and creep steel, heat-resistant steel and low temperature steel, dissimilar steel welding, low alloy steel repair, etc.
2. Ferritic-austenitic steel connections with operating temperatures greater than +300°C and welding applications that do not require post-weld heat treatment. It is suitable for manufacturing pressure vessels with an operating temperature range of -196°C to +550°C, and resists oxidation and peeling within +1200°C (sulfur-free conditions).
3. Resistant to embrittlement and thermal cracking, when welding dissimilar steels, and low carbon diffusion during high-temperature heat treatment.
Typical Base Materials
Alloy 600, Alloy 601, Alloy 690, Alloy 800, Alloy 330, etc.
