Custom Size Nickel Alloy Ring Gasket Metal O Ring Joint Gasket Oil Seal
Nickel alloy gaskets has excellent mechanical properties like tensile, fatigue and creep-rupture, and it has excellent welding characteristics, resistant to postweld age cracking, oxidation resistant throughout its useful temperature range.
Composition:
While the specific composition of a nickel alloy gasket ring can vary, these gasket rings typically contain nickel combined with elements like chromium, molybdenum, and iron to enhance their strength and corrosion resistance. Some common high nickel alloys include:
- Hastelloy (C-4, C-276, X, B-3)
- Inconel (600, 601, X-750)
- Monel (400, K-500)
- Incoloy (020, 028, 825, 925)
Properties:
- High-temperature resistance: Can maintain mechanical integrity in elevated temperatures, often up to 1000°C or more depending on the specific alloy.
- Corrosion resistance: Excellent resistance to a wide range of corrosive environments, such as acidic or alkaline conditions.
- High mechanical strength: Remains strong and ductile even under thermal stress.
- Creep resistance: Ability to resist deformation under high stress at elevated temperatures.
Applications:
- Heat exchangers
- Valves and pumps
- Pressure vessels
- Flanges and pipe fittings
- Reactor vessels and agitators
Standards and Specifications:
- ASTM, ASME, and API specifications may govern the material grade, dimensions, and manufacturing procedures for nickel alloy gaskets to ensure they meet the requirements of the intended service environment.
