Docol R8 Tubing

Docol® Tube R8 is an Advanced High Strength Steel tube with a Dual Phase (DP) microstructure. DP steels consist of a ferritic matrix phase containing a hard-martensitic phase in the form of islands (see image to the right). The soft ferrite matrix gives DP steels its excellent ductility, and the hard-martensitic gives it its strength. The lower-strength ferrite surrounding the islands of martensite create the unique high initial work-hardening rate (n-value) when the steel is deformed. This gives DP Steel a much higher ultimate tensile strength than conventional steels.

The first generation of Advanced High Strength Steels (AHSS) like DP started to make their way into the automotive industry in the mid-1990s and it was heavily adopted in the late ’90s and early 2000s. The use of AHSS in the automotive industry continues to grow as car makers are required to meet more demanding regulations on safety and emissions. Today, these steels are commonly used in door crash bars, roof bows, A&B pillars, bumpers, foot boxes and seats.

In the early 2010’s, A.E.D., partnered with ME Racing and SSAB (Docol® Tube R8’s producing mill), set out to bring AHSS to the racing industry. After many discussions with experts throughout the racing industry, it was concluded that a Dual Phase 800 megapascal steel would offer a safer, stronger and more consistent alternative to 4130 Chrome Moly Cold Drawn Seamless Tube, which has been the industry standard for more than 50 years.

4130 Chromoly Tubing

4130, also known as Chrome Moly (aka chromoly) (so named for 2 key elements of its composition, chromium and molybdenum), is a general-purpose alloy steel that has been widely used by the aviation and motorsports industries for years. Weldability, fabrication, and mild hardenability make it a popular choice in all forms – tube, bar, sheet, and plate.
