Corrosion and toughness
PEA+ steel for extrusion tooling
PEA+ combines a refined precipitation-hardening system with a fine, polishable matrix. It targets a balanced combination of strength, toughness and corrosion resistance for precision dies, polished flow channels and demanding melt-contact tooling.
Where this grade fits
Precision dies, polished flow channels and melt-contact tooling where corrosion, toughness and polishability guide the material choice.

Specify the component and its working conditions
Send the drawing, polymer or contact medium, working temperature, loading, wear or corrosion issue, finish and cleaning method. Patt can review the steel, machining and surface-treatment route together.
