UNS N06600 Inconel 600 Lapped Joint Flanges Manufacturer Stockist Exporter
We are manufacturers, stockist and exporters of UNS N06600 Inconel 600 Lapped Joint Flanges in Mumbai.
Synergy Engineering Solution offers UNS N06600 (Inconel 600) lapped joint (lap-joint) flanges engineered for high temperature, oxidative, and corrosive environments. Inconel 600 is a nickel-chromium-iron alloy known for its excellent combination of corrosion resistance, mechanical strength, and oxidation/heat resistance up to elevated temperatures. The lapped joint flange arrangement consists of a corrosion-resistant stub end (or lap piece) fixed to the pipe, and a loose backing flange that can be freely rotated or aligned without disturbing the pipe connection — offering flexibility in alignment, ease of installation, and convenient dismantling.
As a manufacturer, stockist, and exporter, Synergy maintains full control over the production chain: from procuring high-grade Inconel 600 ingots, forging or machining the stub ends and backing flanges, performing precision machining and finishing, to carrying out quality inspections and issuing material certifications. Because Inconel 600 requires careful metallurgical control to preserve its high-temperature and corrosion properties (especially avoiding contamination or unwanted phases), Synergy’s in-house capabilities in forging, heat treatments (annealing, stress relief), machining, and NDE testing are key to delivering reliable parts. As a stockist, they retain a range of standard sizes and pressure classes for faster order fulfillment, while also accommodating custom sizes or thicknesses for special projects.
In terms of performance, Inconel 600 lapped joint flanges deliver excellent resistance to a broad array of oxidizing, reducing, and corrosive media, including high-temperature environments with exposures to sulfur, chlorides, and aggressive atmospheres. Their robustness under thermal cycling and high temperature oxidation makes them suitable for applications in furnace hardware, heat treatment systems, petrochemical units, chemical plants, gas turbine assemblies, and process piping where both mechanical strength and corrosion / oxidation resistance are required. The lapped joint design is especially advantageous in process systems needing periodic inspection, cleaning, or rotating connections where bolt alignment flexibility is beneficial.
In performance terms, Nickel 201 (UNS N02201) provides a strong combination of corrosion resistance, ductility, and mechanical strength. Its chemical composition limits carbon to ~0.02 wt %, with impurities like Fe, Cu, Mn, Si below ~0.40–0.35 wt % and sulfur ≤ 0.01 %. This low carbon makes 201 more stable at elevated temperature than 200 in certain reducing or carburizing environments. In annealed condition, typical tensile strengths are ~345 MPa (50 ksi) or more, with yield strengths (0.2 % offset) in the ~70–100 MPa range, and elongation of ~40–50 % or higher in typical product forms. Its density is about 8.9 g/cm³, and its melting behavior is comparable to other pure nickel alloys (melting ~1,445 °C). Because of the low carbon, Alloy 201 is often chosen over 200 when the operating environment includes modest temperatures where carbon diffusion or carbides might otherwise degrade performance.

Synergy’s export reach for Inconel 600 lapped joint flanges spans the Middle East (Oman, Qatar, Saudi Arabia, UAE, Kuwait), Europe (Spain, Germany), North America (USA, Canada), and Africa, as well as other global regions. Their export services include preparation of full documentation (mill test certificates, traceability reports, third-party inspection as needed), secure packaging for long transit, customs clearance support, and logistic coordination to meet delivery schedules. Their experience in handling international standards, project specifications, and cross-border compliance helps ensure reliable supply to demanding petrochemical, power, and industrial clients globally.
Because Inconel 600 is not precipitation hardenable, it is typically furnished in the annealed or solution-annealed condition, but offers good workability and weldability. Typical mechanical properties in the annealed condition include ultimate tensile strength around ~655 MPa (95,000 psi) and yield strength ~310 MPa (45,000 psi) with elongation ~40–45 % in many product forms. Synergy ensures that each flange is tested for dimensional accuracy, hardness, and mechanical conformity, and supplies certifications of material compliance and testing to support critical engineering projects.

Frequently Asked Questions (FAQ)
Q: What is the main difference between Nickel 200 and Nickel 201?
Nickel 201 (UNS N02201) has a lower carbon content (≤0.02%) compared to Nickel 200, making it more suitable for higher temperature applications above 600°F (316°C).
Q: Why are lapped joint flanges preferred in some piping systems?
The backing flange can be rotated to align bolt holes, making installation and disassembly easier. They are especially useful in systems requiring frequent inspection or cleaning.
Q: What certifications are provided with Synergy’s flanges?
