Stainless Steel 304LN Pipes bring higher strength than 304L to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 304LN?
Grade 304LN stainless steel belongs to the Austenitic family. It contains 18% Cr, 8% Ni, low carbon, nitrogen. This composition gives the material its higher strength than 304L.
GXH Steels manufactures Stainless Steel 304LN Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing without nitrogen, Stainless Steel 304L Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 304LN Pipes apart:
- Corrosion Resistance – Excellent at low temperatures.
- Temperature Performance – Rated for service -196°C to 870°C.
- Material Composition – Contains 18% Cr, 8% Ni, low carbon, nitrogen for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring better corrosion resistance may also benefit from Grade 316LN Pipes.
