HyGear signs supply contract for hydrogen in the metal industry


Onsite gas generation specialist HyGear has secured another long-term supply contract for hydrogen (H2) to a leading global metallurgy company.

The company will use the H2 in its large-scale sintering process.

HyGear explained in a statement that pure H2 is often seen as the most effective atmosphere for high-temperature sintering of metal powders during compaction into a solid form. The temperature is usually near melting point of many powder metallurgy parts. H2 helps to maximise corrosion resistance and the key properties of density. The reason for high temperature sintering with H2 is to reduce surface oxides and remove impurities from the alloy.
