• Flat Face (FF) Flanges
Used in systems with flat mating surfaces, especially where non-metallic or brittle materials are involved.
• Forged Welding Neck Flanges
Provide enhanced strength, impact resistance, and dimensional precision.
• Custom-Machined Flanges
Available in various sizes, pressure classes, and Inconel grades tailored to customer specifications.
Inconel Grades and Composition:
1. Inconel 600 (Nickel-Chromium Alloy)
Composition:
• Nickel (Ni): Balance
• Chromium (Cr): 14.0 – 17.0%
• Iron (Fe): ≤ 6.0%
• Carbon (C): ≤ 0.15%
• Manganese (Mn): ≤ 1.0%
• Silicon (Si): ≤ 0.50%
Applications:
Commonly used in chemical processing, heat exchangers, and systems exposed to high-temperature oxidation and carburization, as it provides excellent resistance to both oxidation and carburization.
2. Inconel 625 (Nickel-Chromium-Molybdenum Alloy)
Composition:
• Nickel (Ni): Balance
• Chromium (Cr): 20.0 – 23.0%
• Molybdenum (Mo): 8.0 – 10.0%
• Iron (Fe): ≤ 5.0%
Applications:
Ideal for high-stress, high-temperature applications, such as jet engines, rocket motors, and heat exchangers, due to its outstanding fatigue and thermal-fatigue strength.
3. Inconel 718 (Nickel-Chromium Alloy)
Composition:
• Nickel (Ni): Balance
• Chromium (Cr): 17.0 – 21.0%
• Iron (Fe): ≤ 18.0%
