Product Overview

What are Nimonic 75 Threaded Rods?

Nimonic 75 threaded rods are high-temperature nickel-chromium alloy fasteners manufactured from UNS N06075 bar stock in accordance with ASTM B637. Designed for continuous service up to 1100°C, these rods offer excellent oxidation and scaling resistance, as well as moderate strength and good ductility. The alloy’s 20% chromium content ensures robust corrosion resistance in oxidizing environments, while titanium additions provide grain boundary stability for reliable performance in thermal cycling applications.

Nimonic 75 threaded rods are widely specified for furnace fixtures, gas turbine assemblies, and petrochemical plant supports where both mechanical integrity and resistance to high-temperature corrosion are critical. All rods are supplied with full traceability and EN 10204 3.1 certification.

Material Chemistry

Nimonic 75 Chemical Composition

Nimonic 75 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.

Chemical Composition per ASTM B637

ElementComposition (%)
Nickel (Ni)72.0% min
Chromium (Cr)19.0-21.0%
Iron (Fe)5.0% max
Titanium (Ti)0.2-0.6%

Why Nimonic 75 Alloy Composition Matters for Threaded Rods

Cr (19–21%) — Oxidation Resistance
High chromium content forms a stable oxide layer, protecting Nimonic 75 threaded rods from scaling and oxidation at temperatures up to 1100°C, ideal for furnace and turbine applications.
Ti (0.2–0.6%) — Grain Boundary Strength
Titanium additions stabilize grain boundaries, improving creep resistance and preventing embrittlement during long-term high-temperature service.
Low Carbon — Weldability
Low carbon content minimizes carbide precipitation, allowing Nimonic 75 rods to be welded or tack-welded into assemblies without risk of intergranular corrosion.

Nimonic 75 threaded rods are supplied to DIN 975 (full thread metric), DIN 976 (studs), and ASME B18.31.3 (inch series). Custom thread forms such as BSW, BSF, and Whitworth are available on request. All rods are manufactured from ASTM B637 UNS N06075 bar with full traceability and EN 10204 3.1 certification.
Always use a nickel-based anti-seize compound (such as Molykote P-37 or Jet-Lube Pure Nickel) on Nimonic 75 threads to prevent galling and facilitate disassembly after high-temperature service. Avoid copper-based anti-seize to prevent galvanic corrosion. Lubricated torque values should be reduced by 20% compared to dry assembly.
Yes – Nimonic 75 threaded rods are engineered for continuous service up to 1100°C and offer excellent oxidation and scaling resistance. They are widely used in furnace, turbine, and exhaust applications where stainless steel fasteners would fail due to creep or scaling.
There is no formal MOQ for standard metric sizes (M8-M30) held in stock – single rods can be supplied for urgent maintenance. Custom diameters or cut lengths typically require a 10 kg minimum. Price breaks are available at 25, 100, and 250 rods.
