Size Specifications:

Docol Tube R8 are Advanced High Strength certified steel tubes that are engineered to provide a stronger, safer, more consistent alternative to 4130 Chrome Moly Cold Drawn Seamless tube. This will allow you to build a faster, more consistent, longer lasting racecar that allows better utilization of tuning components.

Key Advantages of Docol

  • Stronger than 4130 by 10 to 15 percent.
  • Heat Affected Zone (HAZ) is Docol is much smaller in area, less brittle and retains better elongation than 4130 typically does.
  • 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.
  • Greater resistance to fatigue.
  • Docol absorbs energy and presents a more consistent and controlled failure mode.
  • 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.
  • Accurate and consistent dimensional and mechanical properties because this material is a rolled and welded strip.
  • Compatible with welding to 4130 and mild steel components.
  • Suitable for TIG and MIG welding.
  • Clean "no scrap" based material.
