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 0.25 inches, a wall thickness of 0.016 inches, and an inner diameter of 0.218 inches. It is made from 304 stainless steel, known for its strength and corrosion resistance, especially in high-temperature environments.

No, while 304 stainless steel offers excellent corrosion resistance in most environments, it is not recommended for marine environments. For marine use, 316 stainless steel is a better choice.

Yes, custom cut lengths are available from the warehouse. The maximum length offered is 240 inches, and various standard cut lengths are in stock and ready to ship.

Yes, MTRs are available for this product, providing certified documentation of its material properties and compliance.

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