Explore the Exceptional ERNiCrMo-3 Nickel Alloy Welding Wire
Comprehensive Product Introduction
1. Precision-Crafted Chemical Composition
The ERNiCrMo-3 (AWS A5.14) stands out as a masterful blend of nickel-chromium-molybdenum alloy, meticulously controlled for outstanding high performance:
- Dominant Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%) – forming a solid foundation.
- Controlled Impurities: Minimal iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) significantly reduce cracking possibilities, ensuring reliability.
