4. Welding Process Guidelines
Methods: Supports TIG (GTAW), MIG (GMAW), and SMAW (for ENiCrMo-4 variant) techniques.
Critical Parameters:
Preheat Requirements: Electrodes baked at 350°C for 1 hour following low-hydrogen practice.
Gas Shielding: Utilizes argon of ≥99.99% purity; flow rate maintained at 10-15 L/min.
Current Specifications: DC+ polarity; 70-140 A, adjustable based on diameter.
Essential Practices:
Clean base metal thoroughly (remove rust, oil, and moisture).
Control heat input and interpass temperature to prevent cracking.
5. Product Forms & Availability
Wire: Available in various forms to meet diverse requirements.
Diameters: Available in sizes ranging from 0.6 mm to 3.2 mm, our alloy is conveniently spooled for seamless MIG and TIG welding applications.
Electrode (SMAW):
Diameters: Specifically tailored to meet your needs, available from 1.6 mm to 5.0 mm for precision work.
6. Performance Advantages
Corrosion Resistance: Exhibits exceptional performance, ensuring longevity in:
Acidic media, including environments with sulfuric and hydrochloric acids.
Chloride-induced pitting and crevice corrosion, providing reliable protection and durability.
Crack Resistance: Exhibits remarkable resistance to stress-corrosion cracking (SCC) thanks to its high content of Mo and W.
