Nickel Alloy Monel K500 Stud Bolts Nuts

Description of Nickel Alloy Monel K500 Stud Bolts Nuts

Faced with the extreme demands placed on fasteners in demanding working conditions, Monel K500 stud bolts and nuts utilize an integrated manufacturing concept and a full-process traceability system to provide irreplaceable reliability at critical connection points. The Nickel Alloy Monel K500 Stud Bolts Nuts utilize Monel K500 alloy bar produced through a dual vacuum induction melting (VIM) and electroslag remelting (ESR) process. Homogenization annealing eliminates microsegregation, ensuring a stable grain size within ASTM Grade 5. The bar then enters a CNC turning and milling center, utilizing high-pressure internal cooling and minimal-quantity lubrication technology to simultaneously cut the double-start thread. Thread profiles include metric sizes M6–M80, US UN/UNF 1/4–3 in, and special profiles such as NPT, Tr, and serration. Both end thread lengths and center polished rod length can be precisely customized to customer drawings within a ±0.1 mm tolerance.

The heat treatment phase utilizes a dual "solution treatment + aging" process: solution treatment at 980°C followed by water quenching to fully dissolve the γ' phase; followed by air cooling at 595°C for 8 hours to induce Ni₃(Al, Ti) precipitation strengthening, achieving a hardness of HRC 35–40 while maintaining excellent toughness. Glass shot peening is used at the thread root to introduce a residual compressive stress layer exceeding –600 MPa, significantly improving fatigue resistance. The surface can be brightly passivated, electropolished, or coated with Teflon, depending on the application scenario, ensuring low friction and galling resistance even in extreme environments.

Features of Nickel Alloy Monel K500 Stud Bolts Nuts

High Strength + Precipitation Hardening: Following an aging treatment, the material's tensile strength reaches ≥1100 MPa, yield strength ≥790 MPa, and hardness HRC 27-35. This is roughly 3 times the strength of Monel 400.

Excellent Resistance to Corrosion: Like Monel 400, it is stable in seawater, hydrofluoric acid, and hydrogen sulfide, as well as in chlor-alkali and high sulfur, high wax oil reservoirs, and exhibits no pitting, crevice corrosion, or stress corrosion cracking.

Non-Magnetic and Non-Magnetic Toughness: Remains non-magnetically contaminated and highly impact tough at cryogenic temperatures of −196° C. Also, possesses no ductile to brittle transition temperature, which is favorable in superconducting and precision instrumentation surroundings.

Fatigue and Relaxation Resistance: Under high temperature alternating loads, high-cycle fatigue life surpasses 10⁷ cycles, and preload degradation is negligible, making it ideal for repeated start-stop cycles.

Applications of Nickel Alloy Monel K500 Stud Bolts Nuts

• Marine Engineering: Subsea Christmas trees, seawater pumps, ship propeller shafting, and cryogenic flange pipes for LNG carrier tanks.

• Petrochemical: HF alkylation reactors, chlor-alkali electrolyzers, tools for oil and gas wells downhole, as well as wellhead equipment for high sulfur content oil and gas.

• Aerospace: Components like turbine blade roots, combustion chambers, and structural fasteners for the landing gears of aircraft.

• Energy and Power: The seawater cooling systems for nuclear power plants and supercritical steam turbine high-temperature, high-pressure valves.
