Alloy family
Inconel Alloys — Nickel-Chromium High-Temperature & Corrosion Resistant Grades
Inconel is a family of nickel-chromium alloys known for high-temperature strength and oxidation resistance. Key grades — 600, 601, 617, 625, 690, 718, X-750 and 725 — serve aero-engines, nuclear steam generator tubing, chemical plant and offshore.
Why specify this alloy family
Oxidation resistance
Forms a dense Cr₂O₃ / Al₂O₃ surface film
Strength
Age-hardened 718 reaches ~1400 MPa tensile
Weldability
Matched with ERNiCrMo-3 / ERNiCr-3 filler
