Stainless Steel 304N Pipes bring improved yield strength to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 304N?
Grade 304N stainless steel belongs to the Austenitic family. It contains 18% Cr, 8% Ni, nitrogen added. This composition gives the material its improved yield strength.
GXH Steels manufactures Stainless Steel 304N Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing standard strength, Stainless Steel 304 Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 304N Pipes apart:
- Corrosion Resistance – Slightly better than 304 in chlorides.
- Temperature Performance – Rated for service up to 870°C continuous.
- Material Composition – Contains 18% Cr, 8% Ni, nitrogen added for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring low-carbon variant may also benefit from Grade 304LN Pipes.
