25.2.2.5 High Nickel Alloys. High nickel alloys containing 25% to 65% Ni are the most resistant to both CO2 and H 2 S corrosion. No limits are given for CO 2 corrosion, whereas H 2 S corrosion is a function of the nickel content. Inconel alloys, UNS N08825 and UNS N06625, are the most widely used high nickel alloys in the oil industry.

nickel processing - Extraction and refining | Britannica

Various processes are used to treat nickel matte. One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer.In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.

How to Do At Home Nickel Plating: Everything You Need to Know

Nickel plating refers to any process that covers a metal object in a protective layer of nickel or nickel alloy. If you're interested in doing this at home, your only realistic option is nickel electroplating, although there are services out there that offer alternative nickel-plating methods as well.There are two main reasons to nickel-plate an object—to protect it, or improve its overall ...

Six stocks to ride the nickel boom

Nickel has risen in price from US$8,260 a tonne at the start of 2016 to just under US$19,000 a tonne –touching a nine-and-a-half-year high of US$19,700 a tonne in February. The price is up by 9% in 2021. In the short term, however, the nickel market is expected to remain in surplus in 2021, driven by increasing nickel supply from Indonesia.
