<p>Docol Tube R8 are certified tubes that are engineered to provide a stronger, </p>
<p>safer, more consistent alternative to 4130 CD seamless tube. This will allow you to build </p>
<p>a faster, more consistent, longer lasting racecar that allows better utilization of tuning </p>
<p>components</p>
<p></p>
<p>Mechanical Properties: </p>
<ul><li>Tensile Strength Min.: 116,000 PSI</li><li>Yield Strength Min.: 100,000 PSI</li><li>Elongation
min. % in 2”: 13%</li><li>Diameter Tolerance: +/- .006" <br></li><li>Wall Thickness Tolerance: +/- .005”
</li></ul>
<p></p>
<p><b>Key Advantages: <br></b></p>
<p>• Stronger than 4130 by 10 to 15 percent. <br></p>
<p>• Heat Affected Zone (HAZ) is Docol is
much smaller in area, less brittle and
retains better elongation than 4130
typically does. <br></p>
<p>• Docol is much more tolerant to heavy
fabrication. It does not warp and distort
like 4130 and stays more relaxed in
tooling and fixtures during fabrication. <br></p>
<p>• Greater resistance to fatigue. <br></p>
<p>• Docol absorbs energy and presents a
more consistent and controlled failure
mode. <br></p>
<p>• Clean mill finish product - minimal, if any,
surface prep required. Docol does not
have an oxide or decarb layer and looks
like a high quality electric welded tube.</p>
<p>
• Accurate and consistent dimensional
and mechanical properties because this
material is a rolled and welded strip. <br></p>
<p>• Compatible with welding to 4130 and
mild steel components. • Suitable for TIG and MIG welding. <br></p>
<p>• Clean "no scrap" based material.</p>
<p></p>
<p><b>Technical Information:</b> </p>
<p>• As a seam-welded product, for best
forming results, it is recommended to
orient the seam in the neutral
position. <br></p>
<p>• Welding recommendations:
ER80SD2 filler material for both TIG
and MIG welding. <br></p>
<p>• Docol as a finished tube is NOT heat
treatable material. Any attempt to
heat treat Docol may result in what is
known as a "dead soft" material with
minimal strength value.</p>
