Nickel 200 Round Bars are a solid solution strengthened commercially pure wrought alloy bars. The chemical limitations of both alloys are merged into a single, dual-certified process, resulting in a single alloy with the desirable properties of both alloys. If operating temperatures are expected to exceed 600 degrees F, the carbon content becomes crucial.

Industries & Applications

Several different industries use Ni 200 Round Bars, but they are particularly useful to those who seek to preserve the purity of their products. Nickel 200 Round Bars are commonly used in the pharmaceutical and electronics industries. It is also used in the petrochemical, aerospace, power generation, and marine and offshore engineering industries. Typical applications where Nickel 200 Round Bars are being used include electronic and electroplating devices, caustic evaporators, food manufacturing equipment, caustic handling and storage equipment, synthetic fiber production, salt manufacturing and other industries where sodium hydroxide and fluorine are often used.

Resistance to Corrosion

Ni 200 Round Bars provide superior resistance to corrosion in both low and neutral media as well as in oxidizing environments, provided that the oxidizing medium allows the creation of a passive oxide film. This oxide film is responsible for the excellent corrosion resistance of the alloy in caustic conditions. Nickel 200 Round Bars are often used in alkaline-containing conditions and have varying applications in sulphuric, hydrochloric, anhydrous and non-aerated organic acids. Nickel 200 Round Bars are stress corrosion cracking resistant in chloride salts and to attacks from non-oxidizing halides. Concentration and temperature can affect the resistance of alloys in certain conditions.

Fabrication and Heat Treatment

Both hot and cold working practices can be used to shape the Nickel 200 Round Bars. Hot working temperatures should be between 1200 degrees F and 2250 degrees F with intense formation to be done at temperatures above 1600 degrees F. Annealing should be done at a temperature between 1300 degrees F and 1600 degrees F. Care should be taken when selecting the annealing temperature as time-to-temperature, as this may have a significant impact on the mechanical properties and structure of the material.
