3. Key Applications
Primary Use: Perfect for welding Hastelloy C-276 and similar Ni-Cr-Mo alloys, ensuring high performance and compatibility.
Dissimilar Metal Joining:
Effortlessly join Nickel alloys ↔ Stainless steel/low-alloy steel
with seamless transitions to Nickel alloys ↔ Carbon steel, maintaining integrity and strength.
Cladding & Repair: Provides a superior surface overlay on steel, boosting corrosion resistance.
Industries Served: Ideal for chemical processing, oil/gas, aerospace, flue gas desulfurization (FGD), and cryogenic services down to -196°C.
4. Welding Process Guidelines
Methods: Versatile in TIG (GTAW), MIG (GMAW), and SMAW (for ENiCrMo-4 variant).
Parameters to Perfect:
Preheat: Baked at 350°C for an hour to ensure a low-hydrogen practice.
Gas Shielding: Utilizes ≥99.99% pure argon for optimal protection; flow rate maintained at 10-15 L/min for efficiency.
Current: Operates at DC+ polarity; adjustable range of 70-140 A, varying with diameter for precision.
Critical Practices:
Ensure the base metal is immaculate (remove rust/oil/moisture) for flawless welding.
Low heat input and interpass temperature are essential to prevent cracking.
5. Product Forms & Availability
Wire: Available in various forms to meet your specific welding needs.
Diameters: 0.6-3.2 mm, expertly spooled for seamless MIG/TIG operations.
Electrode (SMAW): A powerful choice for superior welding results.
Diameters: 1.6mm-5.0 mm, accommodating a broad range of welding needs.
6. Performance Advantages: Where excellence meets reliability.
Corrosion Resistance: Unparalleled protection in the most challenging environments:
Acidic media (sulfuric, hydrochloric acids): Exceptional endurance.
Chloride-induced pitting/crevice corrosion: Impenetrable defense.
Crack Resistance: Minimal susceptibility to stress-corrosion cracking (SCC) thanks to the high Mo/W blend.
