Nimonic 101 Fasteners — Material Overview & Form Factors

Nimonic 101 is a high-performance alloy used wherever standard fasteners cannot meet the corrosion, temperature, or strength envelope. TorqBolt manufactures the full Nimonic 101 fastener range — bolts, nuts, screws, washers, studs, and custom forgings — under one ISO 9001:2015 quality system, with PED 2014/68/EU module-H qualification for pressure-equipment service.

Where Nimonic 101 Excels

Nimonic 101 is specified in oil & gas wellhead components, refinery heat exchangers, petrochemical reactors, power-generation turbines, marine offshore platforms, and pharmaceutical / food-grade processing. Its corrosion resistance, high-temperature strength, and weldability make it the default for service conditions outside the carbon and standard-stainless envelope.

Form Factors Available

Bolts — hex, heavy hex, socket, button, countersunk; M6–M100 / 1/4"–4"

Nuts — standard, heavy, jam, locking variants (nyloc, all-metal, flange)

Screws — cap, machine, set, shoulder, self-tapping; all common drive types

Washers — plain, spring, lock, Belleville, fender, tab

Studs & threaded rod — ASTM A193 / A320 / A453 / A540

Custom forgings — rings, blanks, shaped components to drawing

Standards & Certification

Nimonic 101 fasteners are supplied with EN 10204 3.1 (mill cert) or 3.2 (third-party witnessed) material test reports as standard. Additional certification packages: NACE MR0175 / ISO 15156 (sour service), NORSOK M-650 (subsea / topside), API 6A (wellhead), API 20E (subsea bolting), PED 2014/68/EU (pressure equipment). Third-party inspection by TUV, Lloyd's, BV, DNV, SGS, and Intertek arrangeable on order.

Lead Time & Sizes

Stock items in standard Nimonic 101 fastener sizes ship in 1–2 weeks; custom-manufactured items in 4–6 weeks subject to material availability. Diameters M6–M100 and 1/4"–4", lengths 10 mm–3000 mm covered in-house; oversize / non-standard sizes quoted to specification.

Nimonic — Nickel-Chromium Wrought Superalloys

Nimonic is a family of wrought nickel-chromium superalloys originally developed for jet-engine turbine blade and bolting service, where steady-state operating temperatures exceed 700°C under high cyclic stress. Composition centers on ~50-75% Ni, 15-22% Cr, 0-20% Co with Ti+Al additions for γ' precipitation hardening. Nimonic alloys retain creep strength well beyond the limits of conventional Fe-Ni-Cr superalloys.

Nimonic 75 (UNS N06075) is the simplest grade: solid-solution Ni-Cr without precipitation hardening, used for furnace fixtures and mild-temperature bolting to 760°C. Nimonic 80A (N07080) adds Ti+Al for age-hardening — tensile ~1100 MPa, the workhorse of steam-turbine and exhaust-valve bolting per ASTM B637 / AMS 5662. Nimonic 90 (N07090) adds 16-20% Co for service to 920°C with stress-rupture life suitable for gas-turbine combustor bolts.

Nimonic fasteners ship per ASTM B637 / B564 with EN 10204 3.1 / 3.2 certs covering chemistry, hardness (HRC 30-42), tensile at room + elevated temperature, and stress-rupture acceptance per the heat-treat condition. NACE MR0175 sour-service compliance available in solution-annealed condition.
