Nickel Alloy Flanges

Hastelloy C-22 Flange Hastelloy C-22 Alloy 22 (UNS N06022; W. Nr. 2.4602; NiCr21Mo14W) is one of the well-known and well-proven nickel-chromium-molybdenum materials, the chief attributes of which are resistance to both oxidizing and non-oxidizing chemicals, and protection from pitting, crevice attack, and stress corrosion cracking. Its high chromium content provides much higher resistance to oxidizing media than the family standard, C-276 alloy, and imparts exceptional resistance to chloride-induced pitting, an insidious and unpredictable form of attack, to which the stainless steels are prone.

Inconel 718 is a nickel-based superalloy ideal for applications requiring high strength in the temperature range from cryogenic to 1400¡ãF. Inconel 718 also has excellent tensile and impact strength.

Inconel 718 has good resistance to oxidation and corrosion at temperatures within the effective strength range of the alloy in the atmospheres encountered in jet engine and gas turbine operation.

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.

ASTM B564 UNS N10276 Flanges have a small amount of tungsten added to help resist the growth of grain boundary precipitates that reduce corrosion resistance. Hastelloy C22 flanges have better corrosion resistance than most other grades and are an upgrade to the C276 Hastelloy grade. They are important flanges because of their excellent versatility and resistance to chloride-induced pitting.

Inconel 600 flanges are made from materials containing carbon, manganese, silicon, sulfur, copper, iron, nickel and chromium. This is a nickel-chromium alloy as it contains at least 72% nickel and 14% chromium.

There are different types, such as UNS N06600 butt weld flanges with welded necks, which can be used to hold the pipe in place. Butt weld flanges are more common in larger diameter piping systems.

Nickel has good heat resistance properties on its own, but when alloyed with other elements it acquires many properties, like Inconel 600 flanges. Due to the alloy’s good weldability and high tensile strength over a wide range of temperature conditions.

ASTM B564 UNS N06600 alloy is used in a variety of corrosion resistant applications. Alloy 600’s high nickel content provides resistance to reducing environments, while the material’s chromium content provides resistance to weaker oxidizing environments. The material has excellent resistance to chloride stress corrosion cracking.

The high nickel content of Alloy 600 provides good resistance to moderately reducing conditions. The nickel content of the alloy makes the alloy extremely resistant to chloride ion stress corrosion cracking. Alloy 600 is an alloy used in magnesium chloride solutions.

Inconel 601 flanges are made of nichrome. The material grade varies with the composition ratio. The composition of grade 601 is 58% nickel, 21% chromium, carbon, manganese, silicon, sulfur, copper and iron.

Inconel 625 has high corrosion and oxidation resistance, high strength and toughness, and excellent fatigue strength. This non-magnetic nickel-based alloy also offers an extremely wide operating temperature range – from cryogenics to 2,000¡ãF (1,093¡ãC).

Excellent corrosion resistance to a wide range of corrosive media. Alloy 625 is normally supplied in the annealed condition for wet corrosion applications and is T¨¹V certified for use in pressure vessels with a temperature range of -196¡ãC to 450¡ãC.

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.

Alloy C22 flanges are particularly parallel to Alloy C276 and are also an excellent corrosion and heat resistant product. At the same time, the nickel-chromium-molybdenum material it forms also contains tungsten, which enhances a complete erosion barrier compared to most different parallel products. Our UNS N06022 flanges prevent push erosion damage, hole consumption and set-up. These are available to our profitable customers at very affordable prices and come in a range of spans, divider thicknesses and sizes.
