ERNiCrMo-3 Nickel Alloy Welding Wire
Product Introduction
1. Chemical Composition
ERNiCrMo-3 (AWS A5.14) is a high-performance nickel-chromium-molybdenum alloy, meticulously formulated with precise elemental control to deliver exceptional results in demanding conditions:
- Primary Elements: Nickel (Ni: 58-62%), Chromium (Cr: 20-23%), Molybdenum (Mo: 8-10%), Niobium (Nb: 3.15-4.15%)
- Impurities: Carefully limited impurities such as iron (Fe ≤1.0%), sulfur (S ≤0.02%), and phosphorus (P ≤0.015%) effectively minimize the risk of cracking, enhancing the integrity of the weld.
