Prodec® for improved machinability
Marcegaglia Stainless Sheffield has developed a highly improved machinable bar carrying name Prodec. It stands for grades optimized for consistently superior machinability, enabling faster machining speed, longer tool life and enhanced quality. Prodec is melted in melt shop in UK giving 100% European origin for the bars.
• Faster machining
• Longer tool life
• Superior quality – tolerance and surface
• European origin
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.
