Stainless Steel 409L Pipes bring improved weldability over 409 to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 409L?
Grade 409L stainless steel belongs to the Ferritic family. It contains 11% Cr, Ti, low carbon. This composition gives the material its improved weldability over 409.
GXH Steels manufactures Stainless Steel 409L Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing standard carbon, Stainless Steel 409 Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 409L Pipes apart:
- Corrosion Resistance – Better weld-zone properties.
- Temperature Performance – Rated for service up to 815°C continuous.
- Material Composition – Contains 11% Cr, Ti, low carbon for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring superior corrosion resistance may also benefit from Grade 304 Pipes.
