ERNiCrMo-13 is a high-performance, low-carbon, low-silicon nickel-chromium-molybdenum welding alloy (equivalent to Alloy 59/UNS N06059) known for exceptional corrosion resistance in harsh chemical environments, including oxidizing/reducing media, strong acids, chlorides, and seawater, offering high strength, thermal stability, and superior weldability without tungsten, making it perfect for critical chemical processing, marine, and power generation applications.
Key Characteristics & Benefits:
Superior Corrosion Resistance: Excellent against strong oxidizing agents (nitric acid, chlorine), reducing acids (sulfuric, hydrochloric), and chloride-induced pitting/crevice corrosion.
Low Impurities: Extra low carbon and silicon content prevents sensitization and intergranular corrosion, even without post-weld heat treatment.
High Strength & Stability: Provides high mechanical strength and excellent thermal stability.
Excellent Weldability: Minimal hot cracking sensitivity and good processing features.
No Tungsten: Resists grain-boundary precipitation during hot forming.
Primary Applications:
Chemical Processing: Welding Alloy 59, C-22, C-276, and joining nickel alloys to stainless steels in aggressive media.
Marine & Offshore: Resists corrosion in seawater and chloride solutions.
Power Generation & Pollution Control: Used in sulfuric acid coolers, digesters, and bleach plants.
Sour Gas Environments: Approved for highest test levels in sour-gas (H2S) conditions (ISO 15156/MR0175).
