Stainless Steel 301LN Pipes bring higher strength through nitrogen to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 301LN?
Grade 301LN stainless steel belongs to the Austenitic family. It contains 17% Cr, 7% Ni, nitrogen added. This composition gives the material its higher strength through nitrogen.
GXH Steels manufactures Stainless Steel 301LN Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing added nitrogen, Stainless Steel 301L Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 301LN Pipes apart:
- Corrosion Resistance – Better than 301l in chloride environments.
- Temperature Performance – Rated for service up to 870°C intermittent.
- Material Composition – Contains 17% Cr, 7% Ni, nitrogen added for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring comparable strength may also benefit from Grade 304LN Pipes.
