Stainless Steel Welded 316 Pipe

Our 316 welded stainless steel pipe provides superior corrosion resistance for marine and industrial chemical applications. These pipes are commonly used for saltwater transport, chemical exhaust lines, and wastewater treatment systems. The addition of molybdenum in the 316 alloy offers exceptional protection against chloride-induced pitting and crevice corrosion. This material is the standard choice for offshore energy and naval engineering due to its rugged durability. Onlinemetals.com stocks 316 welded pipe in multiple sizes to help you build systems that last in harsh environments.
