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.

This seamless 316 stainless steel round tube has an outer diameter of 0.4375 inches, a wall thickness of 0.035 inches, and an inner diameter of 0.3675 inches. It is made from alloy 316 stainless steel, known for its high strength and excellent corrosion resistance, especially in marine environments.

Yes, custom cut lengths are available from the warehouse. The tube can be ordered in various lengths up to a maximum of 240 inches, with options including 12, 24, 36, 48, 72, 96, 120, and 240 inches.

Absolutely. The 316 stainless steel alloy is rated as a marine metal and maintains its strength and corrosion resistance in cryogenic and high-temperature environments, making it ideal for marine, aerospace, and other demanding applications.

Yes, material test reports (MTRs) are available for this product. It also complies with RoHS and REACH regulations, ensuring it meets important environmental and safety standards.

Seamless tubing, like this 316 stainless steel tube, is manufactured without a weld seam, making it stronger and more reliable than welded tubing. This makes it a preferred choice for critical applications requiring high strength and corrosion resistance.
