Description
Engineered for maximum durability, precision, and reliability, the Marine-Grade 316L Stainless Steel Round Bar (95.2 mm / 3¾″) is the ultimate choice for demanding environments. Manufactured from a premium low-carbon 316L alloy, this solid stainless rod offers exceptional resistance to corrosion, pitting, and crevice attack, even in saltwater, chemical, and high-moisture conditions.
The molybdenum-enriched composition gives it superior chloride resistance, while the low-carbon design ensures excellent weldability with minimal carbide precipitation—preserving strength and structure after fabrication. Its precision-ground finish guarantees consistent dimensions and smooth surfaces, ideal for high-accuracy machining, CNC work, and custom fabrication projects.
Trusted in industries worldwide, from marine and offshore engineering to structural frameworks, heavy industrial equipment, food processing, and architectural steelwork, this 316L stainless steel round bar delivers professional-grade performance you can count on.
