ERNiCrMo-3 Nickel Alloy Welding Wire
Product Introduction
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a meticulously engineered nickel-chromium-molybdenum alloy. Crafted with precise elemental control, it delivers exceptional high-performance results:
- Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%)-these essential components form the backbone of its robust structure.
- Impurities: Carefully minimized impurities such as low iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) significantly reduce the risk of cracking, ensuring reliability.
