Welding and Fabrication

When welding is required, 304L Stainless Steel Square Tube (.03 max carbon content) is recommended. This grade can be readily welded using all common methods, making it ideal for:

• Fabrication projects
• Tooling applications
• Custom manufacturing
• Structural installations

The low carbon content in 304L stainless steel square tube specifically prevents carbide precipitation during welding, ensuring optimal performance in welded applications.
