Stainless Steel 316H Pipes bring improved creep strength to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 316H?
Grade 316H stainless steel belongs to the Austenitic family. It contains 17% Cr, 12% Ni, 2.5% Mo, higher carbon. This composition gives the material its improved creep strength.
GXH Steels manufactures Stainless Steel 316H Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing standard temperature use, Stainless Steel 316 Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 316H Pipes apart:
- Corrosion Resistance – Excellent at high temperatures.
- Temperature Performance – Rated for service up to 870°C continuous service.
- Material Composition – Contains 17% Cr, 12% Ni, 2.5% Mo, higher carbon for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring welded applications may also benefit from Grade 316L Pipes.
