STANAL 400™ is a solid-phase metallic diffusion treatment performed at 400 °C that improves the galling resistance of stainless steel components without affecting their corrosion resistance.
Main characteristics:
- Greater surface hardness
- Improves wear and galling resistance
- Preserves excellent intrinsic corrosion protection
- Provides a reliable base for self-lubricating coatings
Applicable materials:
- Austenitic stainless steels
- Martensitic stainless steels
- Structurally hardened stainless steels
- Refractory steels
- Steel alloys
Representative applications:
Electrical connectors – Ball joints for handling hot gases in jet engines – Hydraulic connections – Stainless steel bolts for the nuclear sector – Various components for nuclear valves – Hinge pins for submarine doors – Fastening bolts for steam turbine blades
