Product Overview

What are Nimonic 105 Screws?

Nimonic 105 screws are high-performance nickel-chromium-cobalt fasteners manufactured from UNS N13021 bar stock, conforming to ASTM B637. This precipitation-hardened superalloy is engineered for exceptional strength and oxidation resistance at temperatures up to 1050°C, making it ideal for critical aerospace and turbine applications.

With a typical tensile strength exceeding 1100 MPa and excellent creep resistance, Nimonic 105 screws are specified for gas turbine engines, high-temperature bolted joints, and exhaust assemblies where conventional stainless steels and lower-grade nickel alloys fail. All fasteners are supplied with full traceability and heat treatment certification.

Material Chemistry

Nimonic 105 Chemical Composition

Nimonic 105 Screws 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)49.0-55.0
Chromium (Cr)15.0-17.0
Cobalt (Co)19.0-21.0
Titanium (Ti)1.2-1.7

Carbon (C)0.12 max

? All heats verified by NABL-accredited spectrometry. PMI available on request.

Why Nimonic 105 Alloy Composition Matters for Screws

Al + Ti (5–7%) — Precipitation Hardening
Aluminium and titanium additions enable ?' precipitation, giving Nimonic 105 screws their outstanding high-temperature strength and creep resistance, essential for turbine and engine fasteners.
Cobalt (19–21%) — Thermal Stability
Cobalt enhances hot strength and oxidation resistance, allowing Nimonic 105 screws to maintain integrity at temperatures up to 1050°C in gas turbine and exhaust environments.
Zr + B — Grain Boundary Strengthening
Zirconium and boron improve grain boundary cohesion, reducing the risk of intergranular cracking and extending the service life of screws under cyclic thermal loads.

Nimonic 105 Screws — Frequently Asked Questions

Browse expert answers to common questions about Nimonic 105 Screws 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 screws selection and pricing.
Nimonic 105 socket head screws are available to DIN 912 (metric), ISO 4762, DIN 7991 (countersunk), and ASME B18.3 (inch series). Set screws and custom thread forms (UNC, UNF, BSW) can be supplied on request with short lead times for aerospace and industrial applications.
Always use a nickel-based anti-seize compound (such as Molykote P-37 or Jet-Lube Pure Nickel) on Nimonic 105 screws to prevent galling and facilitate disassembly. Avoid copper-based anti-seize, as it can cause galvanic corrosion with nickel alloys at high temperatures.
Yes – Nimonic 105 screws are engineered for sustained service at temperatures up to 1050°C, with excellent creep and oxidation resistance. They are widely used in turbine engines, exhausts, and furnace assemblies where standard alloys would fail.
No MOQ for standard sizes (M6-M20) held in stock – single-piece orders are accepted for urgent maintenance. Custom sizes or non-standard threads typically require a 5 kg minimum. Price breaks are available at 50, 200, and 500 pieces.
