Prodec

Stainless steels for superior machinability

Browse Prodec range specifications Visit Stainless Steel Finder

Stainless steel grades optimized for improved machinability with longer tool life and enhanced quality.

Prodec range for superior machinability 

The Prodec range comprises stainless steel grades that are optimized for consistently superior machinability, enabling faster machining speed, longer tool life, and enhanced quality.

Extensive technical knowledge and our end-to-end production chain enables us to optimize the material's machinability properties through all steps of the process.

Unlike typical grades optimized for machinability, Prodec products have similar corrosion resistance to conventionally produced stainless steel grades.
