Inconel Flanges quality certificates

Inconel Flanges delivered with a 3.1 certificate. we can perform the tests required to issue a 3.2 certificate, or a CMTR in accordance with the ASME III Code.

Inconel Flanges Packaging & Shipping

Inconel Flanges Packed

We mark the Inconel Flanges as needed with the most suitable marking technique. Our staff has extensive experience in export documentation,packaging, and finance. We have found that the biggest key to a successful export transaction is communication.

So, besides the fact that we can arrange freight transportation for you, we can before that:

  • specifically mark parts or packages;
  • provide for a special packing according to what is required by the shipping method or by you.

We focus on every procedure to assure quality, the package we usually take is pack the fittings with environmental poly bags, and then in free fumigation wooden cases or wooden palte When packaging and packing, our experienced warehouse staff systematically takes the greatest precautions for your Inconel Flanges to be optimally protected during transportation. We pack the Inconel Flanges according to the appropriate method: strapped pallet, wooden crate, overseas packing (ISPM15).

Inconel Flanges Useful info

Two other popular industrial flanges material grades include titanium flanges and aluminum flanges. These industrial flanges are typically ordered for projects that require project managers to save on weight but maintain strength. You can find a full range of aluminum flanges and titanium flanges by contacting us here at Siddhagiri.

About Inconel/Nickel Alloys

Inconel alloys are oxidation and corrosion resistant materials well suited for service in extreme environments. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally-induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation strengthening, depending on the alloy.

Incoloy Alloys

Incoloy alloys, including Incoloy 800 and Incoloy 825, are highly sought after due to their ability to resist both oxidization and carbonization in high-temperature settings. The majority of Incoloy alloys make additions to a nickel-iron-chromium base. These additions allow the alloy to adapt to the needs of a variety of industries and enable leading metal companies to offer a range of Incoloy shapes and designs.

Inconel 600: Solid solution strengthened

Inconel 601: Good oxidation resistance at high temperatures and resistance to chloride-ion stress-corrosion cracking, corrosion by high-purity water, and caustic corrosion.

Inconel 617: An exceptional combination of metallurgical stability, strength, and oxidation resistance at high temperatures.

Inconel 625: Acid resistant, good weldability

Inconel 718: Gamma double prime strengthened with good weldability

Inconel 722: Age-hardenable by heat treatment

Inconel 725: A nickel-chromium-molybdenum-niobium alloy that is highly resistant to corrosion and is age hardenable for extremely high strength.

Inconel 750: Precipitation-hardenable, corrosion and oxidation resistance, high strength at high temperatures.

AL-6XN: Low carbon, high purity, nitrogen-bearing “super-austenitic” stainless alloy. The alloy was designed to be a seawater resistant material and has since been demonstrated to be resistant to a broad range of very corrosive environments.

Inconel 800, Incoloy 800: Has excellent tensile strength and resistance to oxidation as well as carburzation properties.

Inconel 825, Incoloy 825: Great resistance to many corrosive environments, such as pitting, crevice corrosion, intergranular corrosion, and stress- corrosion cracking.

Inconel 925: A precipitation-hardenable nickel-iron-chromium alloy with additions of molybdenum and copper.

Inconel 945: An age hardenable nickel-iron-chromium alloy with additions of molybdenum, copper, niobium, titanium and aluminum.
