Advanced High Strength Steel Tubing

AK Tube offers an extensive selection of Electric Resistance Welded (ERW) Advanced High Strength Steel Tubing products, offering mill lengths as well as a selection of cutting and end finishing options.

As automakers are challenged to improve safety and fuel economy, Advanced High Strength Steels (AHSS) has allowed engineers to meet required standards for safety, efficiency, emissions, manufacturability, durability, and quality.

Advanced High Strength Steel Tube (AHSS) are complex and sophisticated materials, whose chemical composition and microstructures result from controlled heating and cooling processes. Various strengthening techniques are used to achieve a range of strength, ductility, toughness, and fatigue. They are lightweight and engineered to meet challenges of today’s automobiles for safety, emissions and performance at affordable costs.
