Product Overview

What are Nimonic 80A Threaded Rods?

Nimonic 80A threaded rods are high-strength nickel-chromium alloy fasteners manufactured from UNS N07080 bar stock, conforming to ASTM B637. This precipitation-hardened alloy is strengthened by additions of titanium and aluminium, providing exceptional creep and oxidation resistance up to 815°C. Nimonic 80A threaded rods are widely specified for bolted joints in high-temperature environments where standard stainless steels fail due to thermal relaxation or scaling.

These rods are commonly used in gas turbine engines, exhaust manifolds, and petrochemical furnace assemblies, where their ability to maintain mechanical integrity under cyclic thermal loads is critical. All Nimonic 80A threaded rods are supplied with full traceability and certification to international standards.

Material Chemistry

Nimonic 80A Chemical Composition

Nimonic 80A Threaded Rods are manufactured from a precipitation-hardened nickel-chromium-cobalt superalloy with titanium and aluminium additions per AMS and BS HR specifications. These elements form the gamma-prime (Ni₃Al,Ti) precipitate phase that delivers creep rupture strength above 700°C — a performance level unachievable with standard nickel or stainless alloys.

Why Nimonic 80A Alloy Composition Matters for Threaded Rods

Ti + Al — Precipitation Hardening
Titanium and aluminium additions enable ?' precipitation hardening, giving Nimonic 80A threaded rods their high tensile and creep strength at elevated temperatures, essential for turbine and furnace bolting.
Cr (18–21%) — Oxidation Resistance
High chromium content forms a stable oxide layer, protecting the rods from scaling and oxidation up to 815°C, far beyond the limits of stainless steel fasteners.
Low Carbon & Controlled Boron
Low carbon and trace boron levels prevent grain boundary embrittlement, ensuring ductility and toughness after long-term high-temperature exposure.
