Stainless Steel 422 Pipes bring high-temperature strength martensitic to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 422?
Grade 422 stainless steel belongs to the Martensitic family. It contains 12% Cr, Mo, W, V. This composition gives the material its high-temperature strength martensitic.
GXH Steels manufactures Stainless Steel 422 Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing lower temperature, Stainless Steel 410 Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 422 Pipes apart:
- Corrosion Resistance – Good for dry elevated temperature.
- Temperature Performance – Rated for service up to 650°C continuous.
- Material Composition – Contains 12% Cr, Mo, W, V for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring turbine applications may also benefit from Grade 403 Pipes.
