</b></font><p align="left"><font face="Arial">Precision gage blocks are
the primary standards vital to dimensional quality control in the

for a precision gage block are <b>accuracy, surface finish, wear resistance and dimensional stability</b>. Other factors are corrosion resistance, hardness, thermal conductivity and coefficient of expansion.</font></p>

<ul>
<li><font face="Arial"><b>Traditional High G-Grade Steel</b> gage blocks, which are generally used in shop floor environments. </font></li>
<li><font face="Arial"><b>Tungsten Carbide </b>gage blocks, which have the advantage of being harder and longer wearing than steel. (Not available from Webber.) </font></li>
<li><font face="Arial"><b>Ceramic</b> gage blocks have and advantage over regular steel. They will outwear regular steel and they will not corrode. </font></li>
<li><font face="Arial"><b>Chromium Carbide</b> gage blocks are considered the top of the line-the finest available. They outwear regular steel and ceramic. In addition, they will not corrode and are very stable and accurate, and have exceptional "wringing" qualities. </font></li>

The reason that our Webber Gage Division emphasizes gage blocks made from Chromium Carbide is because they are the most stable measuring devices ever developed. </font></li>
</ul>
<p align="left"><font face="Arial">NO ONE IN THE WORLD EXCEPT STARRETT/WEBBER HAS PRODUCED THE ACCURACY AND STABILITY OF OUR CROBLOX® GRAND MASTERS. They were produced in 1955 of Chromium Carbide material to an accuracy within one millionth of an inch (.0000254 mm) and have been checked periodically by the U.S. National Bureau of Standards and the U.S. National Institute of Standards and Technology (N.I.S.T.) and have remained stable over this period.</font></p>
