Actual mechanical properties may vary depending on welding parameters, joint design, and base material condition.

Ø Excellent corrosion resistance in both oxidizing and reducing media in a wide variety of chemical process environments, with better corrosion resistance than Alloy 276 and Alloy 625.

Ø Outstanding resistance to stress corrosion cracking, pitting and crevice corrosion in chloride‑containing and aggressive aqueous environments.

Ø Low‑hydrogen coating minimizes hydrogen‑induced cracking, particularly critical for high‑strength steels and thick sections.

Ø Excellent all‑position operability with a slag system that promotes great operability especially out‑of‑position.

Ø Smooth arc characteristics with low spatter, easy slag removal, good porosity resistance, and stable mechanical properties of deposited metal.

Ø Good resistance to hot contaminated sulphuric and phosphoric acids, acetic acid and acetic hydride, and other contaminated oxidizing mineral acids.

Ø Versatile for dissimilar metal joints between nickel‑chromium‑molybdenum alloys and stainless, carbon or low‑alloy steels.

Ø Excellent fabricability for overlay cladding on carbon, low‑alloy and stainless steels.

Polarity: Direct Current, Electrode Positive (DCEP / DC reverse polarity)

Pre‑weld Preparation:

• Clean base metal thoroughly to remove all oil, grease, paint, rust, moisture, and other contaminants prior to welding
• For nickel alloy and stainless steel base materials, ensure strict cleanliness to prevent weld defects

Electrode Conditioning:

• Electrodes must be baked at 300‑350°C (570‑660°F) for 1 hour before use to remove moisture from the low‑hydrogen coating
• Do not rebake electrodes more than twice

1. What is ENiCrMo‑10 welding electrode used for?

ENiCrMo‑10 is primarily used for welding HASTELLOY® C‑22® (UNS N06022) and other nickel‑chromium‑molybdenum alloys, including Inconel® 622, Inconel® 625, and Incoloy® 825. It is also ideal for dissimilar metal joints between Ni‑Cr‑Mo alloys and stainless steel, carbon steel, or low-alloy steels, as well as for overlay cladding on steel substrates.

2. What are the key corrosion resistance properties of ENiCrMo‑10?

ENiCrMo‑10 offers excellent corrosion resistance in both oxidizing and reducing media. It is highly resistant to stress corrosion cracking, pitting, and crevice corrosion, especially in environments with acetic hydride, acetic acid, phosphoric acid, hot contaminated sulfuric acid, and other contaminated oxidizing mineral acids.

3. How does ENiCrMo‑10 compare to ENiCrMo‑3 (Inconel 625 electrode)?

ENiCrMo‑10 (C‑22 type) provides superior corrosion resistance compared to Alloy 625 and Alloy 276 in many aggressive environments. It is especially effective where pitting, crevice corrosion, and stress corrosion cracking are concerns. The addition of tungsten (2.5‑3.5%) enhances localized corrosion resistance in chloride‑containing environments.

4. What polarity and current are required?

ENiCrMo‑10 should be used with Direct Current, Electrode Positive (DCEP / DC reverse polarity). The recommended current range depends on the electrode diameter and the specific application.

5. What is the recommended interpass temperature?

To maintain corrosion resistance and avoid overheating, it is recommended to limit heat input to a maximum of 1.0 kJ/mm with an interpass temperature of no more than 100°C (212°F) for wire applications.

6. How should ENiCrMo‑10 electrodes be stored and conditioned?

Due to its low‑hydrogen coating, ENiCrMo‑10 electrodes must be stored in a dry environment. Before use, bake the electrodes at 300‑350°C (570‑660°F) for 1 hour to remove moisture and prevent hydrogen-induced cracking. Avoid rebaking more than twice.

7. Is preheating required for ENiCrMo‑10 welding?

For most applications, preheating is not necessary. However, for thick sections or high‑constraint structures, preheating may improve weld quality and reduce cracking risks.

8. What base materials can be welded with ENiCrMo‑10?

This electrode is compatible with a range of base materials, including ASTM B574, B575, B619, B622, and B626 with UNS No. N06022, as well as Inconel 622, Inconel 625, Incoloy 825, and other nickel‑chromium‑molybdenum alloys.
