Steels - Determination of nitrogen (trace amounts) - Spectrophotometric method
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).
Stähle - Bestimmung von Stickstoff (Spurengehalte) - Photometrisches Verfahren
Dieses Dokument legt ein spektralphotometrisches Verfahren zur Bestimmung von Stickstoff in Stählen fest.
Das Verfahren ist in erster Linie für die Bestimmung von Gesamtstickstoff in sehr geringen Gehalten in nicht legierten Stählen bestimmt. Es kann jedoch für jede Eisenlegierung mit niedrigem Stickstoffgehalt angewendet werden, die in Salzsäure löslich ist, vorausgesetzt, dass die säurebeständige Form des Siliziumnitrids nicht vorhanden ist.
Dieses hochresistente Nitrid wurde nur in Proben von Siliziumstählen gefunden, die ohne Aluminiumzusatz hergestellt wurden, und dann auch nur in Blechmaterial.
Das Verfahren ist für Stickstoffgehalte von 0,000 5 % (Masse) bis 0,005 % (Masse) anwendbar.
Aciers - Détermination de l'azote (à l'état de traces) - Méthode spectrophotométrique
Le présent document spécifie une méthode de détermination spectrophotométrique de l'azote dans les aciers.
La méthode est principalement destinée à la détermination de l'azote total en très faible teneur dans les aciers non alliés.
Elle peut toutefois être utilisée pour tout alliage ferreux à bas azote soluble dans l'acide chlorhydrique, pourvu que celui-ci ne contienne pas de nitrures de silicium résistant à l'acide. Ces nitrures très résistants n'ont jusqu'alors été trouvés que dans des échantillons d'aciers au silicium produits sans addition d'aluminium, et donc uniquement dans les tôles.
La méthode est applicable aux aciers, dont les teneurs en azote sont comprises entre 0.000 5 % (en masse) et 0.005 % (en masse).
