Hastelloy, a nickel alloy, is a more exotic and expensive building material than stainless steel, an iron alloy. When working with a highly corrosive substance when stainless steel is judged unsuitable for the procedure, hastelloy is typically the best option. Hastelloy is used in chemical plants, paper mills, and oil refineries where it must withstand high temperatures and chemicals.
Stainless steel is better suited to most applications because it is easier to work with and less expensive but hastelloy offers several advantages. Hastelloy can be cast into almost any shape and sized mold, allowing it to be made into very small parts that would be difficult or impossible to make from stainless steel. Also, because of its strength, hastelloy cannot be magnetized like stainless steel so it does not attract metal particles from your skin or tools that could cause serious problems if you were using them in a chemically hazardous environment.
Hastelloy also has superior corrosion resistance to most substances, except for nitric acid and strong acids. This means that it will not rust and, if cleaned regularly, will last for many years.
Finally, hastelloy is nearly indestructible. It can be cut with a knife and even sawed into smaller pieces without losing its property values.
The nickel-based alloy Hastelloy Alloy It is divided into two groups: those with more molybdenum and those with more chromium. Both are known as Hastelloy. They are all extremely resistant to strong oxidizing solutions and have a long lifespan in reducing agents. The name comes from the founders, Americans Harvey Hubbell and Arthur Hassler, who developed it in 1937.
Hastelloy is used in applications where resistance to corrosion by acids or chemicals is required, such as chemical plants, petroleum refineries, and power stations. It can also be used in vessels where there is a risk of these substances being released, such as storage tanks for gasoline or other fuels.
Because of its excellent corrosion resistance, Hastelloy is often used in equipment that is exposed to highly acidic or alkaline conditions. For example, it is commonly used in acid baths during the production of stainless steel plates. Hastelloy can also be used when high temperatures are required in corrosive environments. For example, it is commonly used as furnace tubes in industrial furnaces.
Hastelloy products are available in various forms including sheets, strips, rods, and tubes. The thickness of each sheet can vary from as little as 0.5mm to 1.5mm, depending on the application. Hastelloy is very resistant to most chemicals so it does not need to be coated for protection.
Hastelloy (r) is a nickel-molybdenum alloy milled by Haynes. Hastelloy (r) comes in a variety of grades, several of which are nickel-chromium-molybdenum alloys. Each of these grades has been tailored for a distinct purpose, although they are all very corrosion resistant. Hastelloy (r) was developed as an alternative to stainless steel for use in aircraft fuel tanks and other applications where resistance to corrosion is important.
Nickel and molybdenum are both metals that are extremely resistant to corrosion when used by themselves. When you add chromium to the mix, you get a stronger alloy. Hastelloy (r) contains between 6 and 8 percent chromium with the rest made up of nickel and molybdenum.
This alloy was first produced in 1951 by DuPont under the name Cor-Ten. It was later renamed Hastelloy (r) after it was discovered that the original name Cor-Ten was already taken by another product. Today, only two manufacturers produce Hastelloy (r): Haynes and ThyssenKrupp Aerospace. Hastelloy (r) is most commonly found in aircraft fuel tanks and other components that require high levels of corrosion resistance.
Hastelloy (r) 940 is one of the highest quality grades of this material. It is immune to most forms of corrosion except for stress corrosion cracking which can eventually lead to failure.
Hastelloy X is a solid-solution-strengthened nickel-chromium-iron-molybdenum alloy with excellent oxidation resistance, high-temperature strength, and stress-corrosion resistance, making it suitable for petrochemical applications. It is used in equipment that contacts petroleum or natural gas without being cleaned after use.
Hastelloy N is an alloy of nickel and chromium with similar properties to Hastelloy X. It is used in equipment that does not come into contact with corrosive substances.
Both grades are widely used in refinery equipment such as furnaces, heat exchangers, valves, and pressure vessels because they have good corrosion resistance at high temperatures (up to 1100 degrees Celsius).
Hastelloy B will outgas at higher temperatures than Hastelloy X or N, so it should be used only in equipment that is not exposed to high temperatures. Hastelloy B is not recommended for use in equipment that is subjected to repetitive heating and cooling cycles because it may become brittle due to the formation of carbides inside the metal.
Hastelloy C has more carbon than Hastelloy B and thus better corrosion resistance at lower temperatures (up to 600 degrees Celsius). It is used in equipment that does not come into contact with corrosive substances or contains additives that prevent its corrosion at high temperatures.
Hastelloy alloys, which are resistant to corrosion, are frequently employed in the chemical processing industries. High resistance to uniform attack, remarkable localized corrosion resistance, good stress corrosion cracking resistance, and simplicity of welding and fabrication are all advantages of Hastelloy process equipment. Hastelloy products are also used in nuclear power plants, space vehicles, military equipment, and other applications where resistance to corrosion is required.
When you use Hastelloy products, you get quality and reliability tools that last and last.
Hastelloy alloys are utilized in a variety of applications, including pressure vessels, nuclear reactors, chemical reactors, and chemical industry pipelines and valves. Hastelloy alloy B-3 belongs to the nickel-molybdenum family of Hastelloy alloys. It is used because of its resistance to corrosion and oxidation at high temperatures.
Applications for Hastelloy B-3 alloy include heat exchangers, boiler tubes, and piping systems for industrial processes. This alloy is also used in catalytic converters due to its ability to with stand high temperatures while still being resistant to oxidation.
Hastelloy B-3 alloy contains 8% molybdenum and 3.5% carbon. These two elements are responsible for the alloy's strength and resistance to corrosion at high temperatures. The remaining percentage is made up of nickel and iron. They provide hardness and toughness to the alloy.
Hastelloy B-3 alloy can be purchased ready-made or as blank material for further processing into useful products. It can also be fabricated into parts at your facility using steel fabrication techniques.
Blank materials must meet quality standards before they are sold. If you plan to fabricate your own products, you will need to have this alloy available in spools or sheets. Blank materials are shipped frozen and should be kept frozen until use.
