Standard Test Methods for Chemical Analysis of Ferroniobium
适用范围:<p>These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications such as Specification <a href="http://myastm.astm.org/SUBSCRIPTION/NewValidateSubscription.cgi?A550-HTML">A550</a>. It is assumed that all who use these test 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.</p><p id="s00002">1.1 These test methods cover the chemical analysis of ferroniobium having chemical compositions within the following limits:<br> <p id="n00001"><table summary="TABLE 1" frame="void" id="n00001" class="rules"> <tr><td align="center" valign="top"> </td><td>Element</td><td align="center" valign="top">Concentration, %</td></tr> <tr><td align="center" valign="top"></td><td align="left" valign="top">Aluminum</td><td align="center" valign="top">2.00 max</td></tr> <tr><td align="left" valign="top"> </td><td>Carbon</td><td align="center" valign="top">0.30 max</td></tr> <tr><td align="left" valign="top"> </td><td>Chromium</td><td align="center" valign="top">2.00 max</td></tr> <tr><td align="left" valign="top"> </td><td>Cobalt</td><td align="center" valign="top">0.25 max</td></tr> <tr><td align="left" valign="top"> </td><td>Lead</td><td align="center" valign="top">0.01 max</td></tr> <tr><td align="left" valign="top"> </td><td>Manganese</td><td align="center" valign="top">3.00 max</td></tr> <tr><td align="left" valign="top"> </td><td>Niobium</td><td align="center" valign="top">40.00 to 75.00</td></tr> <tr><td align="left" valign="top"> </td><td>Phosphorus</td><td align="center" valign="top">0.05 max</td></tr> <tr><td align="left" valign="top"> </td><td>Silicon</td><td align="center" valign="top">4.00 max</td></tr> <tr><td align="left" valign="top"> </td><td>Sulfur</td><td align="center" valign="top">0.03 max</td></tr> <tr><td align="left" valign="top"> </td><td>Tantalum</td><td align="center" valign="top">7.00 max</td></tr> <tr><td align="left" valign="top"> </td><td>Tin</td><td align="center" valign="top">0.15 max</td></tr> <tr><td align="left" valign="top"> </td><td>Titanium</td><td align="center" valign="top">5.00 max</td></tr> <tr><td align="left" valign="top"> </td><td>Tungsten</td><td align="center" valign="top">0.50 max</td></tr></table></p></p> <p id="s00003">1.2 The test methods appear in the following order:<p id="n00002"><table summary="TABLE 2" frame="void" id="n00002" class="rules"> <tr><td align="left" valign="top"></td><td align="center" valign="top">Sections</td></tr> <tr><td align="left" valign="top">Separation of Niobium, Tantalum, and Titanium <br> by the Ion-Exchange Test Method</td><td align="center" valign="top">10-16</td></tr> <tr><td align="left" valign="top"> Titanium by the Photometric Test Method [0.05 % to 5.0 %]</td><td align="center" valign="top">17-21</td></tr> <tr><td align="center" valign="top"> Niobium by the Gravimetric Test Method [40 % to 75 %]</td><td align="center" valign="top">22-23</td></tr> <tr><td align="center" valign="top"> Tantalum by the Gravimetric Test Method [1 % to 7 %]</td><td align="center" valign="top">24-25</td></tr> <tr><td align="center" valign="top"> Tantalum by the Photometric Test Method [0.25 % to 1 %]</td><td align="center" valign="top">26-30</td></tr></table></p></p> <p id="s10003">1.3 The values stated in SI units are to be regarded as standard.
