Superior Material: TP17™ Stainless Steel

Proprietary Stainless Steel, TP17™

The Express Mach3 OS is crafted from TP17™ stainless steel, featuring a 20% higher chromium content than standard stainless steels. This composition offers a brighter finish and superior corrosion resistance. Additionally, TP17™ stainless steel is nearly 250% stronger and five times more durable than conventional stainless steel, allowing for radical new designs that maximize your boat's performance and longevity.
