Nickel is a versatile metal that is used in a wide range of applications, including chemical processing, electronics, aerospace, and marine engineering. There are several grades of nickel, each with unique properties that make them suitable for specific applications. Here is a brief description of nickel products with grades. Nickel 200/201: Nickel 200 and Nickel 201 are commercially pure nickel alloys that are highly resistant to corrosion in various environments.
Nickel alloys are known for their excellent corrosion resistance due to their strong bond between the metals in the alloy. They also have great strength and toughness that makes them ideal for use in applications that require wear resistance or high temperatures. Common uses for nickel alloys include aerospace components, medical implants, marine equipment, valves and pumps, oil and gas production equipment, turbine engines, and nuclear power plant components.
A nickel alloy is composed of two or more metals, with one being nickel as the base metal. The other metals that often form part of an alloy may include iron (Fe), copper (Cu), manganese (Mn), chromium (Cr), molybdenum (Mo) titanium (Ti). Each different combination will result in different properties depending on the purpose it is intended to serve; this is why there are many types of nickel alloys available on the market today. For example, Hastelloy C276 contains an alloy made up mostly of nickel along with molybdenum, chromium, and tungsten, which makes it resistant to corrosion from many types of acids & chemicals.
