Helium is a colourless, odourless and non-toxic inert gas that is now widely used in industrial applications where it plays a significant and valuable role and has key properties. Helium has a number of unique physical and chemical properties that make it a very valuable gas for use in related fields and plays an important role in decision making. The following is a specific introduction to the advantages of helium’s value in industrial applications.
1、Overview of Helium
Helium is a rare gas, the chemical symbol for He is atomic number 2, its chemical properties are not active, in the general state and other substances will not react, chemical properties can be said to be quite stable, can be found in nature. Helium is characterised as being very inert and does not react easily with other substances, while it can be used in a wide range of industries. In addition, helium has a low density, low boiling point and high thermal conductivity, making it a very valuable gas.
2、Helium in gas quenching applications
Helium is one of the most widely used gases in gas quenching. In metal heat treatment, metal parts must be cooled rapidly to change their physico-chemical properties. Helium can cool metals rapidly because it has very good heat transfer properties. In addition, helium prevents the metal from distorting during the quenching process, ensuring that the size and shape of the workpiece remain unchanged. In the processing and manufacturing of all types of metal products, quality can be guaranteed, while at the same time various details can be optimised and all types of problems such as distortion can be avoided.
