Things To Know About Hastelloy Round Bar

What is Hastelloy?

Nickel metal that has been alloyed to increase corrosion resistance is known as Hastelloy. Molybdenum and chromium additions are the main methods used to accomplish this. Hastelloy comes in a variety of grades, each of which is chemically optimized for a particular set of properties.

Hastelloy outperforms other specialty metal products like Incoloy in extremely corrosive environments because it typically contains high amounts of both molybdenum and chromium. The general workability is also improved by the addition of molybdenum. Additionally ductile and simple to fabricate and form, Hastelloy alloys are.

The following characteristics are typically found in Hastelloy grades:

• Excellent corrosion resistance
• Excellent weldability
• Resistant to oxidizing agents and acids

How is Hastelloy manufactured?

Hastelloy is a metal alloy that is produced by mixing raw materials while they are still liquid at high temperatures. There are different grades, each with a unique chemical makeup. A mixture may contain nickel as the remaining component and up to 25% chromium, 5% to 30% molybdenum, and 0% to 30% iron. Depending on the grade, additional additives may include titanium, carbon, tungsten, and vanadium.

The metals can be cast appropriately for further manufacturing once they have been combined, melted, and mixed.

What is Hastelloy used for?

Hastelloy is a fantastic option for any moderate to severely corrosive environments where product lifetime is important because it is designed to have outstanding corrosion resistance. In the chemical and petrochemical industries, it is frequently used for pipes and valves. In the chemical and nuclear industries, it is also utilized in reactor vessels.

UNS N06200 is one of the most widely used Hastelloy grades, though there are many others. This grade is frequently employed in waste management, the production of paper and pulp, and the harsh environments mentioned above.

Characteristics of Hastelloy Round Bar

Hastelloy UNS N06200 Round Bars are used in harsh environments because of the nickel alloy’s properties. It is a nickel-chromium superalloy with a significant amount of molybdenum (15–17 percent ). Low quantities of tungsten and iron are present, and the carbon content is likewise kept to a minimum. The amount of carbide that is deposited during heat treatment and welding is reduced when the carbon content is low.

This indicates that even when used in welded systems, the metal maintains excellent resistance to pitting and crevice corrosion. Other materials may become weaker after being heated during welding, increasing their corrosion resistance. The material’s resistance to corrosion is one of its key characteristics. Even under adverse conditions, this material exhibits exceptional resistance to general corrosion, including stress corrosion cracking, pitting, and crevice corrosion.

Extremely resistant to this include solvents, sulphuric, hydrochloric, and phosphoric acids; strongly oxidizing, acidic, and acid chlorides; conventional and acetic acids; acetic anhydride; liquid chlorine gas; hypochlorites; and chlorine solutions. Because of this, Hastelloy UNS N06200 Round Bars are well-known in the chemical processing sector. It also has a high level of resistance to corrosion caused by seawater.

Applications of Hastelloy Round Bar

These are used in many different applications, such as flue gas desulfurization equipment and chemical process equipment. Although the alloy work hardens like the majority of nickel-base alloys, it is also machinable. These are offered to our esteemed clients at extremely competitive prices in a range of diameters, wall thicknesses, and sizes.

An alloy of nickel, chromium, and molybdenum with unrivaled global corrosion resistance is called Hastelloy UNS N06200. It is resistant to a variety of chemical processing conditions, including seawater and brine solutions, hypochlorite and chlorine dioxide solutions, dry chlorine, formic and acetic acids, acetic anhydride, hot, contaminated mineral acids, solvents, chlorine, and chlorine-contaminated environments (both organic and inorganic). Alloy UNS N06200 is suited for the majority of chemical operations because it doesn’t produce grain boundary precipitates in the weld heat-affected zone when it’s as-welded. It resists stress corrosion cracking and pitting well.

Conclusion

It is difficult to find an alloy that can function in such a rigorous environment. Hastelloy UNS N06200 Round Bars are a commodity worth considering because of their exceptional corrosion resistance to a variety of adverse conditions. It is used in a variety of manufacturing processes and is seen to be one of the most adaptive solutions for challenging circumstances.

Due to the high molybdenum concentration of Hastelloy UNS N06200 Round Bars, they are more resistant to pitting and crevice corrosion. When other materials would not be able to withstand the hard circumstances, it is employed in the more difficult regions of waste fluid treatment systems.

Hastelloy UNS N06200 Round Bars are needed for chemical processing as well. It has been used for a variety of things, including ferric and cupric chloride ions, chlorine, hypochlorite, chlorine dioxide, organic acids, acetic anhydride, seawater, brine, and sour oil and gas fields.
