适用范围：This Subsection of BS 6200 describes a volumetric method for the determination of nitrogen in steel. The method is applicable to nitrogen contents from 0.005 % (m/m) to 0.25 % (m/m) in all types of steel except those containing silicon nitride. NOTE 1. Complete recovery of nitrogen cannot be obtained from steels containing silicon nitride. This nitride has been found only in samples of silicon steels manufactured without aluminium additions, and then only in sheet material. NOTE 2. The titles of the publications referred to in this Subsection of BS 6200 are listed on the inside back page.
