Stainless Round Tube 304 Seamless offers a great mix of strength and corrosion resistance in most situations outside of marine environments. If your project is in a marine environment, choose 316 stainless. 304, the most popular stainless alloy in the world, maintains its properties in high temperature situations. It is typically used in aerospace, food and beverage industry, pressure containers, architectural designs and trim, cryogenic applications, and chemical processing equipment.
Seamless tubing is more expensive but stronger than welded tubing.

This stainless round tube has an outer diameter of 7.25 inches, a wall thickness of 0.375 inches, and an inner diameter of 6.5 inches. It is made from 304 stainless steel, known for its strength and corrosion resistance, especially in high temperature environments.

No, the 304 stainless steel tube is not recommended for marine environments. For such applications, 316 stainless steel is preferred due to its superior corrosion resistance in marine conditions.

Custom cutting is not available from the warehouse for this product, but it is offered in multiple standard lengths ranging from 12 to 72 inches, all in stock and ready to ship.

Yes, material test reports (MTR) are available for this 304 stainless steel seamless round tube, ensuring traceability and quality assurance.

This tube is commonly used in aerospace, food and beverage, pressure containers, architectural trim, cryogenic applications, and chemical processing equipment due to its strength, corrosion resistance, and high temperature performance.
