Nickel 200 is a solid solution strengthened, commercially pure wrought materials with excellent mechanical properties and resistance to corrosion. It also has exceptional resistance to caustic alkalis at different concentrations and temperatures. However, the corrosion resistance is better in de-aerated acid. The alloy has low gas content and vapor pressure, and high thermal and electrical conductivities. Nickel 200 has good ductility and weldability, as well as outstanding mechanical qualities. It also has good magnetic and magnetostrictive properties, as well as good thermal and electrical conductivities, a low gas content, and a low vapour pressure. It's used in a variety of situations where the temperature is less than 315°C (600°F).
Alloy 200 is a 99.6% pure wrought nickel alloy. Sold under the brand names Nickel Alloy Ni-200, Commercially Pure Nickel, and Low Alloy Nickel, Ni 200 offers users a wide range of benefits including its primary component, nickel. Nickel is one of the world’s toughest metals and imparts a number of advantages to this material. Ni 200 has excellent resistance to most corrosive and caustic environments, media, alkalis, and acids (sulfuric, hydrochloric, hydrofluoric). The alloy provides highly ductile mechanical properties across a wide temperature range and good corrosion resistance in neutral to moderately reducing environments. In the annealed condition, the alloy possesses the approximate strength of mild steel.
The nickel alloys are readily fabricated by standard fabrication practices. The materials are covered by a variety of specifications and are assigned maximum allowable stresses in the ASME Boiler and Pressure Vessel Code. Nickel 200 is ferromagnetic and provides high thermal and electrical conductivity in comparison to nickel base alloys, stainless and low alloy steels. Because long term exposures of Nickel 200 in the 800 to 1200°F range can result in precipitation of a carbon containing phase and loss of ductility, the alloy is not recommended for service above 600°F.

Nickel 200 offers excellent corrosion resistance in reducing and neutral media as well as in oxidizing atmospheres, provided the oxidizing media allows the formation of a passive oxide film. This oxide film accounts for the alloy’s excellent resistance to corrosion in caustic environments. Nickel 200 is often used in environments containing alkalies, and it has varying use in sulfuric, hydrochloric, anhydrous hydrofluoric and non-aerated organic acids. Nickel 200 is resistant to stress corrosion cracking in chloride salts and to attack from non-oxidizing halides. Concentration and temperature can affect this alloys resistance in certain environments.
All hot working and cold working practices can be utilized when shaping Nickel 200. Hot working temperatures should be between 1200°F and 2250°F with heavy forming to be performed at temperatures above 1600°F. Annealing should be performed at a temperature between 1300°F and 1600°F. Care should be taken when choosing the anneal temperature as time-at-temperature for this can greatly influence the mechanical properties and structure of the material.
The use of Nickel 200 is prevalent in heat treatment equipment that requires transferring heat from one surface to another. The material’s high-temperature endurance makes it ideal for furnaces, heat exchangers, and other equipment. Additionally, its capacity to work well in high temperatures and challenging environments means that it can withstand a variety of chemical reactions, making it an indispensable tool in the chemical processing industry.
Nickel 200 products comes in various shapes, such as sheets and coils, making it highly versatile. Versatility means it can be used to design various equipment designs, sizes, and structures, which can be customized to meet the specific requirements of a particular chemical processing application. This versatility creates an environment for industry professionals to work in and improve applications through cost-effective and efficient methods.
Its cost-effectiveness is the immense advantage of using nickel 200 in chemical processing. Its resistance to corrosion, high-temperature tolerance, and enduring nature make it a better choice. It offers long-lasting equipment, which results in less maintenance, repair costs, and frequent replacements. Investing in Nickel 200 enabled equipment saves time and money and enhances the quality of the end products, which brings companies value.
