The grades and application direction of common nickel and nickel-based alloys


Nickel and nickel-based alloys have a large family with many members. Common nickel-based alloy products on the market is also a wide variety of different forms, the nickel and nickel alloy is how to classify it? In general, we are classified according to its main alloy components, the following is widely used in chemical equipment nickel and nickel alloy to do a brief introduction:

Pure Nickel (201 UNS N02201)

Good corrosion resistance, antigenic acid and salt, but encountered strong oxidation medium such as nitric acid pure nickel is not enemy.

The outstanding advantage of pure nickel is that it is resistant to caustic alkali, and even has excellent corrosion to molten caustic alkali.

Nickel-Chromium-Iron Alloy 600 UNS N06600

Alloy 600 on the basis of nickel to add chromium, enhance its ability to adapt to the oxidizing environment. Although alloy 600 has general corrosion resistance to inorganic acids, it has excellent corrosion resistance. Therefore, alloy 600 are widely used in the production and storage of fatty acids, hydroxides and alkaline chemicals. Alloy 600 has excellent heat resistance and corrosion resistance, and it can be used normally in high temperature halogen environment, so it is an ideal material for chlorination reaction process. The alloy 600 also has excellent resistance to high temperature degradation such as oxidation resistance, anti-carburizing and anti-nitrogen.
