Nickel Alloy Flanges

Inconel 718 is a nickel-chromium-molybdenum alloy designed to resist a variety of severe corrosive environments, pitting and crevice corrosion. This nickel steel alloy also exhibits extremely high yield, tensile and creep rupture properties at elevated temperatures.

Uses of this nickel alloy range from cryogenics to long-term use at 1200¡ãF. One of the distinguishing features of the Inconel 718 composition is the addition of niobium to allow age hardening, allowing annealing and welding without spontaneous hardening during heating and cooling.

The addition of niobium, along with molybdenum, hardens the matrix of the alloy and provides high strength without the need for a strengthening heat treatment. Other popular nickel-chromium alloys are age hardened by adding aluminum and titanium. This nickel steel alloy is easy to manufacture and can be welded in the annealed or precipitation (age) hardened condition. This superalloy is used in a variety of industries such as aerospace, chemical processing, marine engineering, pollution control equipment and nuclear reactors.

Incoloy 800 flanges (B564 N08810 blind flanges) can be used in heat treatment equipment, chemical and petrochemical processing. Alloy 800 flanges are non-magnetic, high strength and good weldability.

Incoloy 8Incoloy 800 H is an iron-nickel-chromium alloy with the same basic composition as Incoloy 800 with significantly higher creep rupture strength. Higher strength results from tight control of carbon, aluminum and titanium content and high temperature annealing. The 800H modification is to control carbon (0.05 to 0.10%) and grain size (>ASTM 5) to optimize stress fracture properties. Incoloy 800 H has further modifications to the combined titanium and aluminium content (0.85 to 1.2%) to ensure optimum high temperature performance. The alloy is double certified and combines the properties of both forms.

Nickel-chromium-molybdenum alloy Hastelloy is used to make Hastelloy C276 flanges. Nickel, 14.5% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus make up the composition. The melting point of Hastelloy C276 flange is 1370 degrees Celsius.

Hastelloy is a super alloy designed to produce high strength flanges. Hastelloy B2 flanges are solid solution strengthened nickel and molybdenum alloys that exhibit increased resistance to reducing and corrosive media in harsh environments. Hastelloy flanges have excellent resistance to pitting and stress corrosion cracking in pure and non-oxidizing acids. Hastelloy B3 flanges are a slight upgrade to this grade, this flange type exhibits higher thermal stability than B2 grade flanges.

Hastelloy C276 flanges are one of the most commonly used flange types in the Hastelloy family. These flanges are designed for use with high performance alloys, Alloy C276 flanges have excellent resistance to wet chloride gas, chlorine dioxide solutions and hypochlorite.

Both Nickel 200 and Nickel 201 are commercially pure nickel, which means that nickel is their main base metal, making up about 99.6% of the total alloy. Chemically, the main difference between Nickel 200 and 201 is that Nickel 201 is a low carbon version with a carbon content of up to 0.02 of the total alloy. Compared to Nickel 200, where the carbon content is approximately 0.15 maximum of the total alloy.

ASTM B564 UNS N06022 Flange has a design density of 8.69g/cm3. They are widely used in pharmaceutical, offshore drilling systems, power generation, natural gas processing, chemical and other industries

Hastelloy C22 Welded Flanges are widely used in high pressure systems. These flanges can be identified by the long protruding neck which provides support to the pipe when pressure or temperature rises. All our products are manufactured according to international and national standards.

Due to the higher chromium content, Hastelloy C22 alloy flanges (UNS N06022) have better overall corrosion resistance in oxidation corrosion than C-276 and Inconel 625 alloys. More specifically, C22 plate flanges provide better protection when used in certain saturated wet chlorine environments.

Additionally, its high chromium content provides C22 flanges with better resistance to oxidative media than C276. This makes it excellent resistance to chloride-induced pitting, although in most cases it is due to its availability. Hastelloy C22 blind flanges also have excellent resistance to pitting and crevice corrosion and stress corrosion cracking. The use of C22 flanges should be limited to temperatures below 1250¡ãF.

These flanges are resistant to localized corrosion, have good metallurgical stability, and do not brief during heating or welding. These WNR 2.4602 flanges are used as part of chemical processing, pollution control, paper and pulp production, marine seawater, waste treatment applications and more.
