Nickel Alloys Monel K500 Threaded Rods
Nickel Alloys Monel K500 Threaded Rods are continuously threaded bars manufactured from the precipitation-hardenable nickel-copper alloy Monel K500 (UNS N05500). Zeron Fasteners specializes in supplying these superior high-strength rods that are commonly cut to length to create custom stud bolts or anchor bolts for critical applications. This product inherits the excellent corrosion resistance of Monel 400 but offers significantly higher mechanical properties due to the addition of aluminum and titanium and subsequent age-hardening. A crucial feature is the alloy's compliance with NACE MR0175 standards, meaning it resists Sulfide Stress Corrosion Cracking (SSCC) in sour gas service. The primary application of these Monel K500 Threaded Rods is in tension-critical systems within deep-well downhole equipment, structural anchor points on offshore platforms, high-pressure equipment flanges, and marine applications requiring non-magnetic, ultra-strong, corrosion-proof anchoring.
