Key Advantages of Docol R8

•  Stronger than 4130 by 10 to 15 percent
• Heat Affected Zone (HAZ) in Docol R8 is much less in area than 4130, less brittle than 4130, retains better elongation and necking than 4130
• Docol R8 is much more tolerant to heavy fabrication
• Clean mill finish product – minimal, if any, surface prep required
• Accurate and consistent dimensional and mechanical properties due to this material being a rolled and welded strip
• Compatible with welding to 4130 and mild steel
• Use ER 80 S filler material (same as 4130)
• Suitable for TIG and MIG welding
• This is what you want to buy if you plan on welding any brackets or tabs to your bumper support or rad core support
