Inconel washers

Inconel Washers

These washers provide superb large bearing surface which reduces the overall pressure, tension and stress on the other fasteners and surrounding equipment. The Inconel washers are made up of nickel-chromium-molybdenum alloys which display excellent strength at wide range of high temperature. Due to their exceptional chemical Inconel conical washers properties are highly resistance to variety of severe corrosive environments. Inconel flat washers exhibits strong thermal stability and can be used in wide range of high-pressure conditions. Inconel nord lock washers are durable and have strong mechanical properties. These washers are extensively used in the aerospace, marine, oil, gas and chemical processing industries.

The washers are available in various excellent surface finishings which includes phosphating, zinc impregnation, oxidation, Dacromet, electri galvanized and HDG. The are various manufacturing processes used for the washers such as hot forming, cold forming, CNC machining and Bar stock machined. The washers display excellent bearing strength and reduces overall stress by equally distributing the heavy load, high pressure and tension over its large surface area.

Inconel Washers Chemical Composition

Check the online price, advantages & disadvantages of Inconel flat washers as per ASTM B670 in Dubai

Inconel flat washers display strong resistance against corrosion caused by neutral salts, alkaline media, acids and sea water. The nickel-chromium content of Inconel Belleville washers makes them highly resistance to oxidising chemicals whereas the nickel-molybdenum contents provide them strong resistance against non-oxidising environments. Inconel Belleville disc spring maintain their toughness and strength even at elevated temperature up to 9820C. With high ductility the washers are efficient in working in low cryogenic temperature.

Inconel spring washers and spring lock washer available in M2- M30 dia as per ASTM B670, check its properties

Inconel Belleville spring lock washer functions is a kind of disk spring that impose pressure to the connection once you clamp it down with appropriate amount of force. They make use of nuts and bolts which needs to be get tightened around these washers and provide a strong joint. Inconel spring washers are generally used in the operations of high current loading, heavy loads and cycling where you used these washers to connect bare, soft aluminium to copper.

Check applications of Inconel nord lock washers and bevel spring washer as per DIN 2093, DIN 6796

No, Inconel Belleville Spring Washers shouldn’t be flattened as this will comprise their superior functionality and can further lead to bolted joint failure. However, at some instances flat washer are used in some applications to prevent a Belleville disc spring from biting into softer metal. These washers function in their conical shape offering high spring rate, preserve bolt integrity and effectively spread the load.

Check Inconel disc spring washers and belleville conical washers manufacturing process, ask for a sample mill test certificate in Middle East countries

There are various industrial standard testing methods which are used to ensure the quality and industrial standards of Inconel Belleville conical washers. Mill test certificates which make sure that all the chemical and mechanical properties of the washers area accurate and adhere to industrial standards. There are some other testings which are used to detect flaws and damage in the washers which includes:

  • Fracture test
  • Notch impact test
  • Torsion test
  • Fatiguie test
  • Compression tests
  • Hardness test
  • Torque test
