Introduction To Nimonic Alloys

Nimonic Alloys

MOKSH TUBES & FITTINGS LLP is a leading supplier, stockist, and exporter of high-performance Nimonic Alloys, known for their exceptional resistance to heat, oxidation, and corrosion. These nickel-chromium-based superalloys are engineered for extreme temperature applications where mechanical strength and structural stability are vital—especially in aerospace, gas turbines, nuclear reactors, and high-stress environments.

Nimonic Alloys are primarily composed of Nickel (Ni) and Chromium (Cr), often combined with Titanium (Ti) and Aluminum (Al) for precipitation hardening. Popular grades include Nimonic 75, 80A, 90, 105, 263, and others—each suited to specific mechanical and thermal requirements.

Heat Treatment & Strengthening of Nimonic Alloys

Process Temperature Range Purpose
Solution Annealing 1050 – 1200 °C Dissolves precipitates, improves ductility
Aging / Precipitation Hardening 700 – 850 °C Increases high-temperature strength
Stress Relieving 650 – 750 °C Reduces residual stresses
Hot Working 950 – 1150 °C Forging & rolling
Cold Working + Aging Improves strength & creep resistance

📌 Grades like Nimonic 80A, 90 & 105 rely on γ′ (gamma-prime) precipitation for strength.
