Stainless Round Tube 316 Seamless exhibits high strength and excellent corrosion resistance including in marine environments. 316 is slightly stronger than 304 stainless and is rated as a marine metal. 316 maintains its properties in cryogenic or high temperatures. It is typically used in oil and petroleum equipment, aerospace, food processing, pulp and paper processing equipment, textiles, architectural, and marine equipment.


Seamless tubing is more expensive but stronger than welded tubing.
