ASTM E367-03

Standard Methods for Chemical Analysis of Ferroniobium

SIGNIFICANCE AND USE
These methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use these methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.
SCOPE
1.1 These methods cover the chemical analysis of ferroniobiun having chemical compositions within the following limits:ElementConcentration, %Aluminum2.00 maxCarbon0.30 maxChromium2.00 maxCobalt0.25 maxLead0.01 maxManganese3.00 maxNiobium40.00 to 75.00Phosphorus0.05 maxSilicon4.00 maxSulfur0.03 maxTantalum7.00 maxTin0.15 maxTitanium5.00 maxTungsten0.50 max
1.2 The methods appear in the following order:SectionsNiobium, Tantalum, and Titanium by theIon-Exchange Method10-31
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 6.
