Product Overview

What are Nimonic 105 Nuts?

Nimonic 105 nuts are high-strength, nickel-chromium-cobalt alloy fasteners manufactured from UNS N13021 bar stock conforming to ASTM B637. Designed for extreme temperature service, these nuts utilize precipitation hardening via titanium and aluminum additions, achieving tensile strengths exceeding 1100 MPa in the fully aged condition.

Nimonic 105 nuts are engineered for secure fastening in gas turbines, jet engines, and high-temperature bolted joints where creep resistance and oxidation stability up to 1050°C are critical. They are widely specified in aerospace, power generation, and high-performance automotive applications requiring reliable performance under severe thermal and mechanical stress.

Material Chemistry

Nimonic 105 Chemical Composition

Nimonic 105 Nuts 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)Base (=54%)
Chromium (Cr)15.0-16.0%
Cobalt (Co)19.0-21.0%
Titanium (Ti)1.2-1.7%
Aluminium (Al)4.5-5.2%
Carbon (C)0.12% max
Zirconium (Zr)0.12-0.20%
Boron (B)0.003-0.012%
Silicon (Si)1.0% max
Manganese (Mn)1.0% max
Iron (Fe)1.0% max
? All heats verified by NABL-accredited spectrometry. PMI available on request.

Why Nimonic 105 Alloy Composition Matters for Nuts

Al + Ti — Precipitation Hardening
Aluminium and titanium additions enable ?' precipitation, delivering high tensile and creep strength at elevated temperatures. This is essential for nuts in turbine and exhaust assemblies.
Co (19–21%) — Thermal Stability
Cobalt enhances hot strength and oxidation resistance, ensuring Nimonic 105 nuts retain mechanical properties above 900°C in cyclic thermal environments.
Zr + B — Grain Boundary Strength
Zirconium and boron improve grain boundary cohesion, reducing the risk of intergranular cracking under high stress and temperature, which is critical for fastener longevity.

Industry Applications

Nimonic 105 Nuts Applications — Industries & End Uses

Nimonic 105 Nuts from RealBolt are specified across aerospace gas turbines, power generation, and high-temperature furnaces where very good corrosion resistance and 620 MPa tensile strength are required for reliable fastener performance. Click each industry below for detailed application examples.
Nimonic 105 nuts are the standard for turbine blade retention, compressor casings, and exhaust flange assemblies in jet engines and gas turbines. Their high-temperature strength and oxidation resistance ensure secure fastening under extreme thermal cycling and vibration.
Used in turbine casing joints, hot section bolting, and exhaust duct connections in gas and steam turbines. Nimonic 105 nuts maintain preload and resist creep at temperatures where standard stainless steel fasteners fail.
Specified for turbocharger mounting, exhaust manifold joints, and cylinder head assemblies in racing engines, where high-temperature stability and vibration resistance are critical for reliability and safety.
Ideal for securing furnace doors, radiant tube assemblies, and high-temperature fixtures exposed to continuous operation above 900°C, where oxidation and creep resistance are essential.

Nimonic 105 Nuts — Frequently Asked Questions

Browse expert answers to common questions about Nimonic 105 Nuts from RealBolt — covering AMS specification, heat treatment, creep rupture data, max service temperature, sizes, and aerospace certification. Contact our technical team directly for project-specific guidance on Nimonic 105 nuts selection and pricing.
Nimonic 105 hex nuts are available to DIN 934 (metric), ISO 4032, and ASME B18.2.2 (inch hex and heavy hex). Lock nuts and prevailing torque nuts can be supplied to ISO 7042 and ISO 2320. Custom thread forms (UNJ, UNF, BSF) are available on request with 3-4 week lead time.
Use nickel-based anti-seize compound (such as Molykote P-37 or Jet-Lube Pure Nickel) on threads and bearing surfaces. This prevents galling and ensures consistent preload. Do not use copper-based anti-seize on nickel alloys due to galvanic corrosion risk.
Yes – Nimonic 105 nuts are specifically engineered for jet engine, gas turbine, and high-temperature bolted joints. They maintain strength and resist creep up to 1050°C, making them ideal for blade retention, exhaust, and casing assemblies in aerospace and power generation.
No formal MOQ for standard sizes (M8-M24) held ex-stock – we supply from single pieces for urgent maintenance. Custom sizes or special thread forms have an MOQ of 10 kg. Price breaks at 50 pcs, 200 pcs, and 500 pcs for volume orders.
