Hastelloy B2 Flanges come under the ASTM B564 specification with sizes ranging from ? inches to 60 inches under different standards.
The flanges are produced through different techniques as the ASTM B564 Hastelloy B2 Threaded Flanges, screwed flanges, forged flanges and plate flanges. The threaded flanges are used with threaded pipes and the female threaded flanges connect to the male threaded pipe ends.
The Hastelloy UNS N10665 Pipe Flanges come under the ANSI, ASTM, DIN and other international standards with various dimensions and pressure classes.
According to the flange size, wall thickness and diameters, the pressure classes vary from class 150 through class 2500. There are also different faced flanges such as the ring type joint Alloy B2 RTJ Flange, raised face flange and flat face flange.
Each of them have structural differences. These flanges are made up of a nickel, chromium, molybdenum alloy that has 50% nickel 14% chromium, 15% molybdenum and carbon, manganese, silicon, sulfur, cobalt, iron and phosphorus in the composition.
There are different types such as the Hastelloy B2 Slip On Flanges , socket weld flanges, and welded neck flanges. These have 790MPa minimum tensile strength, 355MPa minimum yield strength and 40% elongation rate.
The flanges also have 8.89 grams per cubic centimeter density and 1370 degrees melting point. The DIN 2.4617 Socket Weld Flanges and other flanges are used in high temperature, high corrosive and high stress applications due to the higher mechanical properties.
The material is resistant to chlorides and acids so that the primary uses are in the acid processing, chemical, sea water and marine applications.
We are a manufacturer, trader, stockist, supplier, and exporter of ASTM B564 Hastelloy B2 Flanges that are known as ‘High-performance Flanges’ for their Nickel-Molybdenum combination, alloyed with a lower content of Iron, Silicon and Carbon, which makes them adept in administering control over the conveyance of reducing acids at higher temperatures.
The chemical composition of Hastelloy B2 includes a very small amount of carbon content. Hence, the flanges produced from Hastelloy grade B2 tends to resist the formation of grain boundary carbide precipitates during welding in the weld heat-affected zone.
Hastelloy C22 flanges have a wide range of usage in different industries. Hastelloy C22 alloys are mostly used in pharmaceutical industries for fittings and tubing, and it also helps to avoid contamination, which is mostly caused by corrosion.
Werkstoff’s number 2.4602, Inconel Alloy 22, VDM Alloy 22 and ATI 22 alloy fall under same UNS number.
C22 can be hot worked or cold worked. However, C22 work-hardens rapidly. Therefore, cold working must often be performed in stages with intervening anneals. Parts should be annealed after cold working.
C-22 is used in severely corrosive media with high chloride and temperature applications such as buffer solutions, active pharmaceutical ingredients (API), fabric softeners, cleaning supplies, and fish, soy and chili sauce.
The exceptional corrosion resistance of C22 has promoted its use in many different markets wherever harsh environments are encountered, including the chemical process, pharmaceutical, food processing, oil and gas, power generation, and the paper industries.
C-22 is a great alternative when superaustenitic stainless steels (AL-6XN, 904L, and 254 SMO) and duplex stainless steels (2205 and 2507) will not withstand extremely aggressive media. This is because it is a nickel-chromium-molybdenum-tungsten alloy with better overall resistance to uniform and localized corrosion than any other Ni-Cr-Mo alloy, like Hastelloy C-276, C-4, and alloy 625.
Hastelloy C22, also known as alloy C22, is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking.
The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media.
This nickel steel alloy also has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions.
Other corrosives Hastelloy C-22 has resistance to are oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many mixed or contaminated chemical solutions, both organic and inorganic.
This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi- purpose plants where such ¡°upset¡± conditions occur frequently.
This nickel alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition.
Alloy C-22 should not be used in service temperatures above 1250¡ã F due to the formation of detrimental phases which form above this temperature.
Alloy C22 is a nickel-chromium-molybdenum solid solution strengthened super-alloy with a nominal chemical composition of 56% nickel, 22% chromium, and 13% molybdenum, with additions of iron, tungsten, and cobalt.
It is commonly referred to by the tradename Hastelloy C22 and the universal designation UNS N06022. C22 has excellent corrosion and oxidation resistance, great mechanical properties over a wide range of temperatures, and good fabrication properties.
Alloy C22 is one of the most corrosion-resistant alloys available, even outperforming C276 and 625. It is resistant to almost all reducing and oxidizing environments, including strong oxidizers, seawater, and organic acids.
C22 has excellent resistance to chloride-induced localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking.
Hastelloy C-22 (UNS N06022) pipe bends and fittings in stock, allowing for a quick turnaround. Hastelloy C-22 has excellent resistance to aggressive oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions.
C22 has excellent resistance to oxidation, carburization, and sulfidation at elevated temperatures. However, C22 should not be used at temperatures above 1250¡ãF due to the possible formation of embrittling phases.
Hastelloy C-22 is identified by the Unified Numbering System (UNS) designation of?N06022. It is a nickel based alloy with high nickel (56%), chromium (22%), and molyddenum (13%).
