💡 Important Tip: How to Confirm the Material You Need

There are significant differences between “Ni-Cr-Fe” and “Ni-Fe-Cr.” To ensure you’re selecting the correct material, we recommend the following steps:

1. Verify the Original Technical Documents: Carefully review your original documents, such as drawings, specifications, or purchase instructions. Verify the complete standard number (e.g., the full AWS A5.14 standard) and the base material to be welded (e.g., INCOLOY 825 or INCONEL 600). This is the most critical step.

2. Contact the Material Supplier: Before purchasing, provide the complete standard number and base material information directly to a professional welding material supplier. Ask them to confirm the corresponding product and its technical data certificate.

3. Distinguish between similar grades: It is important to note that ERNiFeCr-1 (if referring to a Ni-Cr-Mo-Cu alloy) and ERNiCrFe-1 (usually corresponding to a Ni-Cr-Fe alloy, such as INCONEL 600) are two materials with significantly different chemical compositions and applications. They are not interchangeable.

Hopefully, this information helps you accurately identify the materials you need. If you can provide more context for your application, perhaps I can provide a more in-depth analysis.
