CEN - PREN 10179

Steels - Determination of nitrogen (trace amounts) - Spectrophotometric method

pending
Organization: CEN
Publication Date: 1 June 2023
Status: pending
Page Count: 18
ICS Code (Chemical analysis of metals): 77.040.30
scope:

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

The method is primarily intended for the determination of total nitrogen in very low contents in non-alloy steels.

It can 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 0.000 5 % (by mass) to 0.005 % (by mass).
