Stainless Steel 420 Pipes bring hardest common martensitic grade to your projects. GXH Steels supplies these pipes for demanding industrial applications where standard grades fall short.
What Is Stainless Steel 420?
Grade 420 stainless steel belongs to the Martensitic family. It contains 13% Cr, higher carbon. This composition gives the material its hardest common martensitic grade.
GXH Steels manufactures Stainless Steel 420 Pipes to meet ASTM and international standards. Each pipe goes through quality checks before shipping.
For applications needing lower hardness, Stainless Steel 410 Pipes provide an excellent choice.
Key Features
Here’s what sets Stainless Steel 420 Pipes apart:
- Corrosion Resistance – Good when properly hardened.
- Temperature Performance – Rated for service up to 650°C.
- Material Composition – Contains 13% Cr, higher carbon for balanced properties.
- Quality Assurance – Every batch includes mill test certificates and documentation.
Projects requiring better machinability may also benefit from Grade 416 Pipes.
