Stainless Steel 403 Pipes bring turbine-grade martensitic to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 403?
Grade 403 stainless steel belongs to the Martensitic family. It contains 12% Cr. This composition gives the material its turbine-grade martensitic.
GXH Steels manufactures Stainless Steel 403 Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing higher carbon, Stainless Steel 410 Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 403 Pipes apart:
- Corrosion Resistance – Moderate, needs clean dry environment.
- Temperature Performance – Rated for service up to 650°C.
- Material Composition – Contains 12% Cr for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring ferritic alternative may also benefit from Grade 405 Pipes.
