Product Overview

What are Nimonic 105 Studs?

Nimonic 105 studs are high-strength nickel-chromium-cobalt alloy fasteners manufactured from UNS N13021 bar stock, conforming to ASTM B637. Designed for extreme temperature service, these studs utilize precipitation hardening via titanium and aluminum additions, achieving tensile strengths exceeding 1100 MPa and maintaining mechanical integrity up to 1050°C.

With excellent oxidation and creep resistance, Nimonic 105 studs are the fastener of choice for gas turbine, aerospace, and high-temperature petrochemical applications where conventional stainless steels and lower-grade nickel alloys fail. All studs are supplied with full traceability and heat treatment certification.

Material Chemistry

Nimonic 105 Chemical Composition

Nimonic 105 Studs 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 (=49%)
Chromium (Cr)15.0-16.0
Cobalt (Co)19.0-21.0
Titanium (Ti)4.5-5.2
Aluminium (Al)4.7-5.2
Carbon (C)0.12 max
Zirconium (Zr)0.12-0.20
Silicon (Si)1.0 max
Manganese (Mn)1.0 max
Boron (B)0.012 max
Iron (Fe)5.0 max
? All heats verified by NABL-accredited spectrometry. PMI available on request.

Why Nimonic 105 Alloy Composition Matters for Studs

Al + Ti (˜10%) — Precipitation Hardening
The high aluminum and titanium content enables ?' precipitation, giving Nimonic 105 studs exceptional strength and creep resistance at temperatures up to 1050°C, ideal for turbine and exhaust flange connections.
Co (19–21%) — Thermal Stability
Cobalt enhances hot strength and oxidation resistance, ensuring stud bolts retain mechanical properties during thermal cycling in gas turbines and high-temperature reactors.
Zr + B — Grain Boundary Strengthening
Zirconium and boron additions improve ductility and resistance to intergranular cracking, critical for stud bolts subjected to vibration and thermal shock.
