Stainless Round Tube 304 Welded 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.
Welded tubing is slightly weaker but more affordable than seamless.

Yes, this stainless steel round tube is available for custom cutting at the warehouse, with maximum lengths up to 144 inches. You can select from various standard cut lengths or request a custom size to fit your project needs.

The 304 alloy offers excellent strength and corrosion resistance for most applications, but it is not recommended for marine environments. For marine use, 316 stainless steel is preferred due to its superior corrosion resistance in such conditions.

This tube has an ultimate tensile strength of 85 ksi, yield strength of 35 ksi, and elongation of 55%, providing a good balance of strength and ductility. It also has a machinability rating of 40 and a density of 8 g/cm³.

Yes, MTRs are available for this product, ensuring traceability and compliance with quality standards.

This product complies with RoHS and REACH regulations, making it suitable for applications requiring these environmental and safety standards.
