AWS 5.14 Class ERNiCr-3
ASME SFA 5.14 Class ERNiCr-3
Application
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.
