IANICROMO3000930TL - Exocor ER625 Inconel TIG Rod 3/32"

Exocor ER625 TIG Rod Technical Overview

The Exocor ER625 (ERNiCrMo-3) TIG welding rod is a high-performance nickel-chromium-molybdenum filler metal designed for the gas tungsten arc welding (GTAW) of Inconel 625, Inconel 601, and other nickel-based alloys. This premium consumable is engineered to meet the rigorous AWS A5.14 specifications, ensuring consistent chemistry and mechanical properties. The alloy's high molybdenum content, combined with niobium, provides significant stiffening of the nickel matrix, resulting in high tensile strength without the necessity for precipitation hardening heat treatments.

One of the defining characteristics of the ER625 alloy is its outstanding resistance to severe corrosive environments. It exhibits exceptional immunity to pitting and crevice corrosion, as well as chloride-ion stress-corrosion cracking. This makes it an essential material for industries operating in aggressive chemical settings. Furthermore, the rod maintains its structural integrity and mechanical properties across a wide temperature range, from cryogenic lows up to 1800°F (982°C), making it suitable for high-temperature service applications where oxidation and scaling resistance are critical.

Metallurgically, the Exocor ER625 is designed to minimize fissuring and provide a ductile, tough weld deposit. It is widely utilized for cladding carbon steel to improve surface corrosion resistance and for joining dissimilar metals, such as stainless steels to nickel alloys. The rod's composition ensures excellent weldability with stable arc characteristics, producing clean, high-quality welds that meet the demanding standards of the petrochemical, nuclear, and aerospace industries.
