Stainless Steel 314 Pipes bring extreme high-temperature scaling resistance to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 314?
Grade 314 stainless steel belongs to the Austenitic family. It contains 25% Cr, 20% Ni, 2% Si. This composition gives the material its extreme high-temperature scaling resistance.
GXH Steels manufactures Stainless Steel 314 Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing comparable heat resistance, Stainless Steel 310 Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 314 Pipes apart:
- Corrosion Resistance – Exceptional at extreme temperatures.
- Temperature Performance – Rated for service up to 1150°C continuous.
- Material Composition – Contains 25% Cr, 20% Ni, 2% Si for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring higher nickel may also benefit from Grade 330 Pipes.
