Stainless Steel 304 Pipes bring most widely used stainless grade to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 304?
Grade 304 stainless steel belongs to the Austenitic family. It contains 18% Cr, 8% Ni. This composition gives the material its most widely used stainless grade.
GXH Steels manufactures Stainless Steel 304 Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing better weldability, Stainless Steel 304L Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 304 Pipes apart:
- Corrosion Resistance – Excellent in most atmospheric and water environments.
- Temperature Performance – Rated for service up to 870°C continuous.
- Material Composition – Contains 18% Cr, 8% Ni for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring superior corrosion resistance may also benefit from Grade 316 Pipes.
