Inconel® materials belong to a family of nickel/chromium alloys that are non-magnetic and take corrosion resistance to elevated temperatures. Chemical composition, mechanical properties, density and specification information are presented in Table 2. Stronger than steel, monel is a malleable, highly corrosion resistant material. Although the alloy tends to work-harden, you can have it successfully spun, deep-drawn, press formed or punched. In hydrofluoric acid, Monel 400 and Hastelloy C2000 are leaders in protection. Ils ont des applications différentes dans l'industrie chimique en raison de leurs compositions chimiques différentes. Yet, Monel 400 can withstand all concentrations of hydrofluoric acid, even up to the boiling point. Hastelloy Vs Monel . Though nickel is critical to corrosion resistance, molybdenium and chromium also play a role in this.

Difference Between Hastelloy and Inconel Hastelloy. However, there are slight difference based on the grade and the material composition. Sorry about that. Monel is also expensive compared to ordinary stainless steel materials but is cheaper compared to the Hastelloy grades. Hastelloy C est également résistante au chlore et des composés contenant du chlore, ainsi que des acides oxydants forts, les mélanges et les sels acides. Inconel Vs Hastelloy; Inconel and Hastelloy chemical and mechanical properties. All of the common methods of welding can be used, although the oxyacetylene and submerged arc processes are not recommended when the fabricated item is for use in corrosion service. A: Inconel 625 and Hastelloy C276 bolts do offer similar corrosion resistance but Hastelloy C276 has a slight edge in many acidic environements, especially when fasteners are in hydrochloric (HCl) and sulfuric (H2SO4) acids. Chemical composition, mechanical properties, density and specification information are presented in Table 2. Compared to steel, Monel could be very tough to machine as it work-hardens very quickly. Alloys of identical chemical and mechanical properties are available from other manufacturers and offer excellent alternatives to the various Hastelloy alloys. It is recommended that Monel 400 is most suitable when fully immersed. It is introduced in wrought or cast forms. They weight twice as much as new machines and all have box ways. Philadelphia, PA 19103 Hastelloy is nickel-molybdenum corrosion-resistant superalloy used for a wide range of chemical processing, pollution control and waste treatment applications. Monel is particularly useful in sea water applications. Hastelloy® is a trademark for a series of high-strength, nickel based, corrosion resistant alloys produced by Haynes International. For instance, Monel alloys consist of copper, which ranges between 30% to 40% of their total weight. Hastelloy® C-22® Why Choice us All that You Need To Know About Us. As such, they have several key characteristics in common.

Difference Between Duplex and Inconel. The nickel content in Monel grades range up to 67% where the copper content can range up to 60% in cupronickel grades. Keep in mind aeration or the presence of oxidizing salts will increase the corrosion rate. It is widely used in various applications involving sulfuric acid of an extensive range of concentrations and temperatures. The key alloying elements of these metals are Chromium, Molybdenum and tungsten, each with their own unique qualities: Chromium enhances corrosion resistance in oxidizing environments. HASTELLOY, HAYNES and C-22 are registered trade names of Haynes International, Inc. MONEL & INCONEL are registered trade names of INCO family of companies. Hastelloy alloy C is a relatively high nickel alloy that is primarily utilized for offering excellent corrosion resistance features. It needs to be turned and worked at gradual speeds and low feed charges. The monel grades have yield strengths up to 345MPa. This is what makes the material stronger and corrosion resistant than most other alloys. We still run older Mitsui Seiki horizontal mills and older Mori Seiki lathes because they are so rigid. Hastelloy is a representation of a family of corrosion-resistant alloys. They can be fabricated readily by hot- and cold-working, machining, and welding. Allegheny Ludlum AL6XN, Krupp VDM alloys 31 and 59, and Haynes Hastelloy C-2000 are included. By Appointment Only, Tampa office The Chlorine Institute Pamphlet 6. Hastelloy® Alloys. As such, they have several key characteristics in common. Monel is a group of nickel alloys, primarily composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon, and silicon. The extra line is the boiling point curve of hydrochloric acid. They have different applications in the chemical industry due to their different chemical compositions. In the case of metallic hose, the inner core must be Monel 400 or Hastelloy C-276 and for non-metallic hoses, the inner core must be PTFE. Tampa, FL 33605 Monel 400 vs. Monel K-500. Permeability is the most commonly cited disadvantage to non-metallic hoses and, in general, given the porosity of PTFE, Monel and Hastelloy do provide a greater degree of safety. Nickel alloys including Hastelloy have a silvery coloration where the Monel can display a yellowish green tinge or hue on the edges. HASTELLOY, HAYNES and C-22 are registered trade names of Haynes International, Inc. MONEL & INCONEL are registered trade names of INCO family of companies. The tensile strength of the Monel grades are also lower than that of the Hastelloy grades. NITRONIC is a registered trade name of Armco, Inc. CARPENTER & 20Cb-3 are registered trade names of Carpenter Technology Corporation. Hastelloy® X alloy is solid solution strengthened, offering outstanding strength at high temperatures. Hastelloy has yield strengths up to 364MPa. While temperature ranges are greater and pressure ratings higher for metallic hoses, in most chlorine applications PTFE will meet both temperature and pressure requirements. Phone: (212) 226-7334 However, in addition to containing nickel as their primary alloyant, they also include other elements as their secondary alloyant. Alloy 200 and Monel 400 act equivalently and offer service at low temperatures about 20 percent content. Hastelloy® C-276 . Stronger than pure nickel, Monel alloys are resistant to corrosion by many agents, including rapidly flowing seawater. Inconel is an oxidation corrosion resistant material well suited for extreme environment services subjected to heat and pressure. What is Inconel? Hastelloy® C-276 . Monel 400® Monel R405® Inconel Nickel Alloys ... Hastelloy C276 in particular is used for a range of welding applications including weld overlay or cladding of steels and once welded, is suitable for almost any chemical process application in even the most severe environments. HASTELLOY® C-276 alloy exhibits high resistance to chloride-induced pitting and crevice attack, forms of corrosion to which the austenitic stainless steels are particularly prone. whereas Monel is used in aerospace applications, oil production, refining, marine applications, musical instruments, etc. Other common names: Alloy C276, Hastelloy C, Inconel® C-276. There are many different grades of Hastelloy®, many of which are nickel-chromium-molybdenum alloys. 1725 East Fifth Avenue Hastelloy 22, Alloy C2000®, Alloy 59, Hastelloy C276 and Inconel Alloy 686 Hastelloy® C2000, Alloy C276, Alloy 686, Hastelloy 22 and Alloy 59 are all nickel based alloys.
