FORMIER 10 is a two-component mixture comprising 90% nitrogen and 10% hydrogen. One of the most popular purging gases in Europe, it is used on austenitic stainless steels – with the exception of titanium-stabilised grades, which can be prone to discolouration. This mixture has the benefit of low surface oxidation as hydrogen acts as a scavenging agent, stopping the formation of a thick chrome oxide layer.
