ERNiCrMo-15 Nickel Alloy Welding Wire for High Fatigue Resistance

Product Description

ERNiCrMo-15 is a premium-grade nickel-chromium-molybdenum alloy welding wire developed specifically for joining Inconel 625LCF and other low-cycle fatigue (LCF) resistant alloys. With optimized composition for enhanced thermal fatigue performance, this wire offers superior durability in cyclic high-temperature environments.

It is suitable for TIG (GTAW) and MIG (GMAW) processes and ensures excellent arc stability, low spatter, and crack-resistant welds. ERNiCrMo-15 is widely used in the fabrication of furnace components, aircraft exhaust systems, chemical reactors, and nuclear containment parts subjected to frequent thermal cycling and mechanical strain.

Key Features

• Excellent resistance to low-cycle thermal fatigue cracking

• Improved high-temperature mechanical strength and stability

• Superior resistance to oxidation, carburization, and aggressive chemical attack

• Smooth and clean weld bead with minimal spatter

• Ideal for service temperatures up to 982°C (1800°F)

• Enhanced metallurgical structure for improved weld durability

• Excellent weldability on Inconel 625LCF and related alloys

• Crack resistance under thermal/mechanical cycling

• Conforms to AWS A5.14 specification for ERNiCrMo-15
