Description

Engineered for uncompromising strength and long-term performance, this Premium Marine-Grade 316L Stainless Steel Round Bar (203.2 mm / 8″) is the ultimate solution for demanding marine, structural, and industrial applications. Made from low-carbon 316L stainless steel, it offers superior corrosion resistance—even in saltwater, chemical, and high-moisture environments—thanks to its molybdenum-enriched composition.

The low-carbon alloy reduces carbide precipitation during welding, ensuring clean, high-strength welds without compromising durability. Precision-ground for exact dimensions and a smooth finish, this heavy-duty rod is ideal for CNC machining, custom fabrication, and high-tolerance engineering projects.

Trusted by professionals worldwide, this 316L stainless steel round bar is perfect for boat fittings, marine frameworks, structural supports, industrial equipment components, and precision-machined parts—delivering exceptional resistance to pitting, crevice corrosion, and rust for years to come.
