Synergy Engineering Solution is a trusted manufacturer, stockist, and exporter of UNS N05500 Monel K500 Plate Flanges, serving industries across Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, the USA, Canada, and several African regions. The company has established a global reputation for delivering high-quality, corrosion-resistant flanges that meet international standards and cater to demanding industrial applications.
Monel K500 (UNS N05500) is a precipitation-hardened nickel-copper alloy, derived from Monel 400 but strengthened by the addition of aluminum and titanium. This unique composition gives Monel K500 Plate Flanges excellent corrosion resistance along with significantly greater strength and hardness compared to Monel 400. It retains its resistance to seawater, salt brine, sour gas, and non-oxidizing acids while offering enhanced mechanical properties, making it ideal for both marine and chemical service.
One of the major benefits of UNS N05500 Monel K500 Plate Flanges is their superior resistance to chloride-induced stress corrosion cracking, erosion, and cavitation. These properties make them highly reliable in offshore oil & gas platforms, marine engineering, chemical processing, pump shafts, and valves. Their ability to withstand subzero temperatures without embrittlement and maintain strength at elevated temperatures further broadens their application range.
At Synergy Engineering Solution, Monel K500 Plate Flanges are manufactured in compliance with ASTM B865 / ASME SB865 standards, ensuring strict dimensional accuracy and durability. The company offers a complete range of flange types including blind, slip-on, weld neck, socket weld, threaded, and lap joint. Available in various pressure ratings and face types (RF, FF, RTJ), these flanges are engineered to perform under high pressure and corrosive conditions.
The mechanical strength of Monel K500 is approximately double that of Monel 400, with a typical tensile strength of around 960 MPa and yield strength of about 690 MPa, while maintaining good ductility and toughness. This combination of strength and corrosion resistance reduces maintenance costs and extends service life in harsh environments, making Monel K500 flanges a preferred choice for critical industries.
With a robust distribution network, Synergy Engineering Solution exports Monel K500 Plate Flanges worldwide, delivering on time with complete quality documentation such as Mill Test Certificates (EN 10204 3.1), third-party inspection reports, and export compliance. Their commitment to quality and customer satisfaction has made them a trusted supplier across global markets.
