Stainless Steel 302 Pipes bring general-purpose austenitic grade to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 302?
Grade 302 stainless steel belongs to the Austenitic family. It contains 18% Cr, 9% Ni. This composition gives the material its general-purpose austenitic grade.
GXH Steels manufactures Stainless Steel 302 Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing slightly higher carbon, Stainless Steel 304 Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 302 Pipes apart:
- Corrosion Resistance – Similar to 304 in most environments.
- Temperature Performance – Rated for service up to 870°C continuous.
- Material Composition – Contains 18% Cr, 9% Ni for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring more work hardening may also benefit from Grade 301 Pipes.
