Scope

This EURONORM specifies a method for the spectrophotometric determination of nitrogen in steels.

The method is primarily intended for the determination of total nitrogen in very low nitrogen non-alloy steels. It may be used, however, for any low nitrogen ferrous alloy that is soluble in hydrochloric acid provided that the acid-resistant form of silicon nitride is not present. This highly resistant nitride has been found only in samples of silicon steels manufactured without aluminium addition and then only in sheet material.

The method is applicable to nitrogen contents from 0,0005 to 0,005 % (m/m).

NOTE The method has also been successfully applied to a pure iron with a nitrogen content of 0,0038 % (m/m) - see Annex.
