SS 316 / SS 316L Stainless Steel Channels
Precision Alloys is a trusted manufacturer and global supplier of SS 316 and SS 316L stainless steel channels, offering corrosion-resistant structural profiles built for demanding applications. Compliant with ASTM A276, ASME SA276, and EN 10088 standards, these channels are ideal for marine, chemical, pharmaceutical, and structural industries requiring high resistance to chlorides, acidic environments, and welding stress.
What are SS 316 / SS 316L Stainless Steel Channels?
SS 316 stainless steel channels are austenitic stainless profiles containing molybdenum (2–3%), enhancing resistance to chloride pitting, saltwater, and chemical exposure.
SS 316L is the low-carbon version of SS 316, offering the same corrosion resistance with improved weldability and protection from intergranular corrosion after welding.
Available in U-Channels, C-Channels, and custom-formed profiles, these grades are engineered for environments that demand durability, hygiene, and structural reliability.
